What to know if your baby is breech

Find out what breech position means, how to turn a breech baby, and what having a breech baby means for your labor and delivery.

What does it mean when a baby is breech?

Signs of a breech baby, why are some babies breech, how to turn a breech baby: is it possible, will i need a c-section if my baby is breech, how to turn a breech baby naturally.

Breech is a term used to describe your baby's position in the womb. Breech position means your baby is bottom-down instead of head-down.

Babies are often active in early pregnancy, moving into different positions. But by around 8 months, there's not much room in the uterus. Most babies maximize their cramped quarters by settling in head down, in what's known as a cephalic or vertex presentation. But if you have a breech baby, it means they're poised to come out buttocks and/or feet first. At 28 weeks or less, about a quarter of babies are breech, and at 32 weeks, 7 percent are breech. By the end of pregnancy, only 3 to 4 percent of babies are in breech position. At term, a baby in breech position is unlikely to turn on their own.

There are several types of breech presentations:

• Frank breech (bottom first with feet up near the head)
• Complete breech (bottom first with legs crossed)
• Incomplete or footling breech (one or both feet are poised to come out first)

(In rare cases, a baby will be sideways in the uterus with their shoulder, back, or arm presenting first – this is called a transverse lie.)

See what these breech presentations look like .

If your baby is in breech position, you may feel them kicking in your lower belly. Or you may feel pressure under your ribcage, from their head.

By the beginning of your third trimester , your practitioner may be able to tell what position your baby is in by feeling your abdomen and locating the baby's head, back, and bottom.

If your baby's position isn't clear during an abdominal exam at 36 weeks, your caregiver may do an internal exam to try to feel what part of the baby is in your pelvis. In some cases, they may use ultrasound to confirm the baby's position.

We don't usually know why some babies are breech – in most cases it seems to be chance. While sometimes a baby with certain birth defects may not turn to a head-down position, most babies in breech position are perfectly fine. Here are some things that might increase the risk of a breech presentation:

• You're carrying multiples
• You've been pregnant before
• You've had a breech presentation before
• There's too much amniotic fluid or not enough amniotic fluid
• You have placenta previa (the placenta is covering all of part of the opening of the uterus)
• Your baby is preterm
• Your uterus is shaped abnormally or has growths, such as fibroids
• The umbilical cord is short
• You were a breech delivery, or your sibling or parent was a breech delivery
• Advanced maternal age (especially age 45 and older)
• Your baby is a low weight at delivery
• You're having a girl

There is a procedure for turning a breech baby. It's called an external cephalic version (ECV). An ob/gyn turns your baby by applying pressure to your abdomen and manually manipulating the baby into a head-down position. Some women find it very uncomfortable or even painful.

An EVC has about a 58 percent success rate, and it's more likely to work if this isn't your first baby. It's not for everyone – you can't have the procedure if you're carrying multiples or if you have too little amniotic fluid or placental abruption , for example. Your provider also won't attempt to turn your breech baby if your baby has any health problems.

The procedure is done after 36 weeks and in the hospital, where your baby can be monitored and where you'll be near a delivery room should any complications arise.

It depends, and it's something you'll want to talk with your caregiver about ahead of time. Discuss your preferences, the advantages and risks of each option ( vaginal and cesarean delivery of a breech presentation), and their experience. The biggest risk of a breech delivery is when the body delivers but the head stays entrapped within the cervix.

In the United States, most breech babies are delivered via cesarean. You may wind up having a vaginal breech delivery if your labor is so rapid that you arrive at the hospital just about to deliver. Another scenario is if you have a twin pregnancy where the first baby is in the head-first position and the second baby is not. A baby who delivers head-first will make room for the breech baby.

However, the vast majority of babies who remain breech arrive by c-section. If a c-section is planned, it will usually be scheduled at 39 weeks. To make sure your baby hasn't changed position in the meantime, you'll have an ultrasound at the hospital to confirm their position just before the surgery.

If you go into labor or your water will break s before your planned c-section, be sure to call your provider right away and head for the hospital.

In rare circumstances, if you're at low risk of complications and your caregiver is experienced delivering breech babies vaginally, you may choose to have what is called a "trial of vaginal birth." This means that you can attempt to deliver vaginally but should be prepared to have a cesarean delivery if labor isn't progressing well. You and your baby will be closely monitored during labor.

In addition to ECV, there are some alternative, natural ways to try to turn your baby. There's no proof that any of them work – or that all of them are safe. Consult your practitioner before trying them.

There's no conclusive proof that the mother's position has any effect on the baby's position, but the idea is to employ gravity to help your baby somersault into a head-down position. A few tips:

• Get into one of the following positions twice a day, starting at around 32 weeks.
• Be sure to do these moves on an empty stomach, lest your lunch comes back up.
• Make sure there's someone around to help you get up if you start feeling lightheaded.
• If you find these positions uncomfortable, stop doing them.

Position 1: Lie flat on your back and raise your pelvis so that it's 9 to 12 inches off the floor. Support your hips with a pillow and stay in this position for five to 15 minutes. Position 2: Kneel down, with your forearms on the floor in front of you, so that your bottom sticks up in the air. Stay in this position for five to 15 minutes. Sleeping position

Many women wonder if there are sleeping positions to turn a breech baby. But the positions you use to try to coax your baby head down for a short time shouldn't be used while you're sleeping. (It's not safe to sleep flat on your back in late pregnancy, for example, because the weight of your baby may compress the blood vessels that provide oxygen and nutrients to them.)

The best position for sleeping during pregnancy is on your side. Placing a pillow between your legs in this position may help open your pelvis, giving your baby room to move more easily. Support your back with plenty of pillows, too. Again, there's no proof that this works, but since it's the best sleeping position for you and your baby, you may as well give it a try.

Moxibustion

This ancient Chinese technique burns herbs to stimulate key acupressure points. To help turn a breech baby, an acupuncturist or other practitioner burns mugwort near the acupressure point of your pinky toes. According to Chinese medicine, this should stimulate your baby's activity enough that they may change position on their own. Some studies show that moxibustion in combination with acupuncture and/or positioning methods may be of some benefit. Others show moxibustion to provide no help in coaxing a baby into cephalic position. If you've discussed it with your caregiver and want to give it a try, contact your state acupuncture or Chinese medicine association and ask for the names of licensed practitioners.

One small study found that women who are regularly hypnotized into a state of deep relaxation at 37 to 40 weeks are more likely to have their baby turn than other women. If you're willing to try this technique, look for a licensed hypnotherapist with experience working with pregnant women.

Chiropractic care

There's a technique – called The Webster Breech Technique – that aims to reduce stress on the pelvis by relaxing the uterus and surrounding ligaments. The idea is that a breech baby can turn more naturally in a relaxed uterus, but research is limited as to the risks and benefits of this technique. If you're interested, talk with your provider about working with a chiropractor who's experienced with the technique.

This is a safe – and again, unproven – method based on the fact that your baby can hear sounds outside the womb. Simply play music close to the lower part of your abdomen (some women use headphones) to encourage your baby to move in the direction of the sound.

INTRODUCTION

This topic will provide an overview of major issues related to breech presentation, including choosing the best route for delivery. Techniques for breech delivery, with a focus on the technique for vaginal breech delivery, are discussed separately. (See "Delivery of the singleton fetus in breech presentation" .)

TYPES OF BREECH PRESENTATION

● Frank breech – Both hips are flexed and both knees are extended so that the feet are adjacent to the head ( figure 1 ); accounts for 50 to 70 percent of breech fetuses at term.

● Complete breech – Both hips and both knees are flexed ( figure 2 ); accounts for 5 to 10 percent of breech fetuses at term.

Fetal Presentation, Position, and Lie (Including Breech Presentation)

• Key Points |

Abnormal fetal lie or presentation may occur due to fetal size, fetal anomalies, uterine structural abnormalities, multiple gestation, or other factors. Diagnosis is by examination or ultrasonography. Management is with physical maneuvers to reposition the fetus, operative vaginal delivery , or cesarean delivery .

Terms that describe the fetus in relation to the uterus, cervix, and maternal pelvis are

Fetal presentation: Fetal part that overlies the maternal pelvic inlet; vertex (cephalic), face, brow, breech, shoulder, funic (umbilical cord), or compound (more than one part, eg, shoulder and hand)

Fetal position: Relation of the presenting part to an anatomic axis; for transverse presentation, occiput anterior, occiput posterior, occiput transverse

Fetal lie: Relation of the fetus to the long axis of the uterus; longitudinal, oblique, or transverse

Normal fetal lie is longitudinal, normal presentation is vertex, and occiput anterior is the most common position.

Abnormal fetal lie, presentation, or position may occur with

Fetopelvic disproportion (fetus too large for the pelvic inlet)

Fetal congenital anomalies

Uterine structural abnormalities (eg, fibroids, synechiae)

Multiple gestation

Several common types of abnormal lie or presentation are discussed here.

Transverse lie

Fetal position is transverse, with the fetal long axis oblique or perpendicular rather than parallel to the maternal long axis. Transverse lie is often accompanied by shoulder presentation, which requires cesarean delivery.

Breech presentation

There are several types of breech presentation.

Frank breech: The fetal hips are flexed, and the knees extended (pike position).

Complete breech: The fetus seems to be sitting with hips and knees flexed.

Single or double footling presentation: One or both legs are completely extended and present before the buttocks.

Types of breech presentations

Breech presentation makes delivery difficult ,primarily because the presenting part is a poor dilating wedge. Having a poor dilating wedge can lead to incomplete cervical dilation, because the presenting part is narrower than the head that follows. The head, which is the part with the largest diameter, can then be trapped during delivery.

Additionally, the trapped fetal head can compress the umbilical cord if the fetal umbilicus is visible at the introitus, particularly in primiparas whose pelvic tissues have not been dilated by previous deliveries. Umbilical cord compression may cause fetal hypoxemia.

Predisposing factors for breech presentation include

Preterm labor

Uterine abnormalities

Fetal anomalies

If delivery is vaginal, breech presentation may increase risk of

Umbilical cord prolapse

Birth trauma

Perinatal death

Face or brow presentation

In face presentation, the head is hyperextended, and position is designated by the position of the chin (mentum). When the chin is posterior, the head is less likely to rotate and less likely to deliver vaginally, necessitating cesarean delivery.

Brow presentation usually converts spontaneously to vertex or face presentation.

Occiput posterior position

The most common abnormal position is occiput posterior.

The fetal neck is usually somewhat deflexed; thus, a larger diameter of the head must pass through the pelvis.

Progress may arrest in the second phase of labor. Operative vaginal delivery or cesarean delivery is often required.

Position and Presentation of the Fetus

If a fetus is in the occiput posterior position, operative vaginal delivery or cesarean delivery is often required.

In breech presentation, the presenting part is a poor dilating wedge, which can cause the head to be trapped during delivery, often compressing the umbilical cord.

For breech presentation, usually do cesarean delivery at 39 weeks or during labor, but external cephalic version is sometimes successful before labor, usually at 37 or 38 weeks.

What Is Breech?

When a fetus is delivered buttocks or feet first

• Types of Presentation

Risk Factors

Complications.

Breech concerns the position of the fetus before labor . Typically, the fetus comes out headfirst, but in a breech delivery, the buttocks or feet come out first. This type of delivery is risky for both the pregnant person and the fetus.

This article discusses the different types of breech presentations, risk factors that might make a breech presentation more likely, treatment options, and complications associated with a breech delivery.

Verywell / Jessica Olah

Types of Breech Presentation

During the last few weeks of pregnancy, a fetus usually rotates so that the head is positioned downward to come out of the vagina first. This is called the vertex position.

In a breech presentation, the fetus does not turn to lie in the correct position. Instead, the fetus’s buttocks or feet are positioned to come out of the vagina first.

At 28 weeks of gestation, approximately 20% of fetuses are in a breech position. However, the majority of these rotate to the proper vertex position. At full term, around 3%–4% of births are breech.

The different types of breech presentations include:

• Complete : The fetus’s knees are bent, and the buttocks are presenting first.
• Frank : The fetus’s legs are stretched upward toward the head, and the buttocks are presenting first.
• Footling : The fetus’s foot is showing first.

Signs of Breech

There are no specific symptoms associated with a breech presentation.

Diagnosing breech before the last few weeks of pregnancy is not helpful, since the fetus is likely to turn to the proper vertex position before 35 weeks gestation.

A healthcare provider may be able to tell which direction the fetus is facing by touching a pregnant person’s abdomen. However, an ultrasound examination is the best way to determine how the fetus is lying in the uterus.

Most breech presentations are not related to any specific risk factor. However, certain circumstances can increase the risk for breech presentation.

These can include:

• Previous pregnancies
• Multiple fetuses in the uterus
• An abnormally shaped uterus
• Uterine fibroids , which are noncancerous growths of the uterus that usually appear during the childbearing years
• Placenta previa, a condition in which the placenta covers the opening to the uterus
• Preterm labor or prematurity of the fetus
• Too much or too little amniotic fluid (the liquid that surrounds the fetus during pregnancy)
• Fetal congenital abnormalities

Most fetuses that are breech are born by cesarean delivery (cesarean section or C-section), a surgical procedure in which the baby is born through an incision in the pregnant person’s abdomen.

In rare instances, a healthcare provider may plan a vaginal birth of a breech fetus. However, there are more risks associated with this type of delivery than there are with cesarean delivery. 

Before cesarean delivery, a healthcare provider might utilize the external cephalic version (ECV) procedure to turn the fetus so that the head is down and in the vertex position. This procedure involves pushing on the pregnant person’s belly to turn the fetus while viewing the maneuvers on an ultrasound. This can be an uncomfortable procedure, and it is usually done around 37 weeks gestation.

ECV reduces the risks associated with having a cesarean delivery. It is successful approximately 40%–60% of the time. The procedure cannot be done once a pregnant person is in active labor.

Complications related to ECV are low and include the placenta tearing away from the uterine lining, changes in the fetus’s heart rate, and preterm labor.

ECV is usually not recommended if the:

• Pregnant person is carrying more than one fetus
• Placenta is in the wrong place
• Healthcare provider has concerns about the health of the fetus
• Pregnant person has specific abnormalities of the reproductive system

Recommendations for Previous C-Sections

The American College of Obstetricians and Gynecologists (ACOG) says that ECV can be considered if a person has had a previous cesarean delivery.

During a breech delivery, the umbilical cord might come out first and be pinched by the exiting fetus. This is called cord prolapse and puts the fetus at risk for decreased oxygen and blood flow. There’s also a risk that the fetus’s head or shoulders will get stuck inside the mother’s pelvis, leading to suffocation.

Complications associated with cesarean delivery include infection, bleeding, injury to other internal organs, and problems with future pregnancies.

A healthcare provider needs to weigh the risks and benefits of ECV, delivering a breech fetus vaginally, and cesarean delivery.

In a breech delivery, the fetus comes out buttocks or feet first rather than headfirst (vertex), the preferred and usual method. This type of delivery can be more dangerous than a vertex delivery and lead to complications. If your baby is in breech, your healthcare provider will likely recommend a C-section.

A Word From Verywell

Knowing that your baby is in the wrong position and that you may be facing a breech delivery can be extremely stressful. However, most fetuses turn to have their head down before a person goes into labor. It is not a cause for concern if your fetus is breech before 36 weeks. It is common for the fetus to move around in many different positions before that time.

At the end of your pregnancy, if your fetus is in a breech position, your healthcare provider can perform maneuvers to turn the fetus around. If these maneuvers are unsuccessful or not appropriate for your situation, cesarean delivery is most often recommended. Discussing all of these options in advance can help you feel prepared should you be faced with a breech delivery.

• Pregnancy Classes

Breech Births

In the last weeks of pregnancy, a baby usually moves so his or her head is positioned to come out of the vagina first during birth. This is called a vertex presentation. A breech presentation occurs when the baby’s buttocks, feet, or both are positioned to come out first during birth. This happens in 3–4% of full-term births.

What are the different types of breech birth presentations?

• Complete breech: Here, the buttocks are pointing downward with the legs folded at the knees and feet near the buttocks.
• Frank breech: In this position, the baby’s buttocks are aimed at the birth canal with its legs sticking straight up in front of his or her body and the feet near the head.
• Footling breech: In this position, one or both of the baby’s feet point downward and will deliver before the rest of the body.

What causes a breech presentation?

The causes of breech presentations are not fully understood. However, the data show that breech birth is more common when:

• You have been pregnant before
• In pregnancies of multiples
• When there is a history of premature delivery
• When the uterus has too much or too little amniotic fluid
• When there is an abnormally shaped uterus or a uterus with abnormal growths, such as fibroids
• The placenta covers all or part of the opening of the uterus placenta previa

How is a breech presentation diagnosed?

A few weeks prior to the due date, the health care provider will place her hands on the mother’s lower abdomen to locate the baby’s head, back, and buttocks. If it appears that the baby might be in a breech position, they can use ultrasound or pelvic exam to confirm the position. Special x-rays can also be used to determine the baby’s position and the size of the pelvis to determine if a vaginal delivery of a breech baby can be safely attempted.

Can a breech presentation mean something is wrong?

Even though most breech babies are born healthy, there is a slightly elevated risk for certain problems. Birth defects are slightly more common in breech babies and the defect might be the reason that the baby failed to move into the right position prior to delivery.

Can a breech presentation be changed?

It is preferable to try to turn a breech baby between the 32nd and 37th weeks of pregnancy . The methods of turning a baby will vary and the success rate for each method can also vary. It is best to discuss the options with the health care provider to see which method she recommends.

Medical Techniques

External Cephalic Version (EVC)  is a non-surgical technique to move the baby in the uterus. In this procedure, a medication is given to help relax the uterus. There might also be the use of an ultrasound to determine the position of the baby, the location of the placenta and the amount of amniotic fluid in the uterus.

Gentle pushing on the lower abdomen can turn the baby into the head-down position. Throughout the external version the baby’s heartbeat will be closely monitored so that if a problem develops, the health care provider will immediately stop the procedure. ECV usually is done near a delivery room so if a problem occurs, a cesarean delivery can be performed quickly. The external version has a high success rate and can be considered if you have had a previous cesarean delivery.

ECV will not be tried if:

• You are carrying more than one fetus
• There are concerns about the health of the fetus
• You have certain abnormalities of the reproductive system
• The placenta is in the wrong place
• The placenta has come away from the wall of the uterus ( placental abruption )

Complications of EVC include:

• Prelabor rupture of membranes
• Changes in the fetus’s heart rate
• Placental abruption
• Preterm labor

Vaginal delivery versus cesarean for breech birth?

Most health care providers do not believe in attempting a vaginal delivery for a breech position. However, some will delay making a final decision until the woman is in labor. The following conditions are considered necessary in order to attempt a vaginal birth:

• The baby is full-term and in the frank breech presentation
• The baby does not show signs of distress while its heart rate is closely monitored.
• The process of labor is smooth and steady with the cervix widening as the baby descends.
• The health care provider estimates that the baby is not too big or the mother’s pelvis too narrow for the baby to pass safely through the birth canal.
• Anesthesia is available and a cesarean delivery possible on short notice

What are the risks and complications of a vaginal delivery?

In a breech birth, the baby’s head is the last part of its body to emerge making it more difficult to ease it through the birth canal. Sometimes forceps are used to guide the baby’s head out of the birth canal. Another potential problem is cord prolapse . In this situation the umbilical cord is squeezed as the baby moves toward the birth canal, thus slowing the baby’s supply of oxygen and blood. In a vaginal breech delivery, electronic fetal monitoring will be used to monitor the baby’s heartbeat throughout the course of labor. Cesarean delivery may be an option if signs develop that the baby may be in distress.

When is a cesarean delivery used with a breech presentation?

Most health care providers recommend a cesarean delivery for all babies in a breech position, especially babies that are premature. Since premature babies are small and more fragile, and because the head of a premature baby is relatively larger in proportion to its body, the baby is unlikely to stretch the cervix as much as a full-term baby. This means that there might be less room for the head to emerge.

• When is Breech an Issue?

The later in pregnancy a baby is   breech , the more difficult it is for the baby to flip head down. The baby’s size grows in relation to the uterus and there is a smaller percentage of amniotic fluid for the baby to move freely. The more complicated past births were due to fetal position, the earlier I suggest starting to get your muscles unwound and your pelvis aligned. If a previous baby remained either   breech   or   posterior   until birth, I suggest bodywork throughout the pregnancy.

In time, the breech baby’s head becomes heavy enough (between 5-7 months) for gravity to bring the head down in a symmetrical womb. The baby will move head down if there is room or if there is tone in the support to the uterus to direct the baby head down.

Common issues with breech:

• Health of the baby overall
• Safety of the birth
• Safety for the mother facing surgical birth
• Emotions of the birthing parent(s)

When should I be concerned about a breech position?

During the month before 30 weeks, about 15% of babies are breech. Since breech baby’s spine is vertical, the womb is “stretched” upwards. We expect babies to turn head down by 28-32 weeks.

Breech may not be an issue until 32-34 weeks. If you know your womb has an unusual limitation in shape or size, such as a   bicornate uterus then begin body balancing before pregnancy and once 15 weeks in pregnancy. In this case, the baby needs to be head down much earlier so that the uterus still has the room for baby to turn. Every unique womb is unique so these dates are theoretical, not absolute.

The timeline for breech

This is a timeline of what to do and when to do it in order to help a breech baby move head down:

• Before 24-26 weeks, most babies lie diagonally or sideways in the   Transverse Lie position .
• Between 24-29 weeks, most babies turn vertical and some will be breech.
• By 30-32 weeks, most babies flip head down and bottom-up.
• By 34 weeks pregnant, the provider expects the baby to be head down.
• Between 36-37 weeks, a provider may suggest an   external cephalic version .
• Full term is from 37-42 weeks gestation, and about 3-4% of term babies are breech.

The medical model of care addresses the breech position between 36-37 weeks, when baby’s survival outside the womb won’t include special nursery care to breathe or suck. Physicians Oxorn and Foote, however, recommend helping babies turn head down at 34 weeks. Some home birth midwives suggest interacting with a baby at 30-34 weeks to encourage a head-down position (vertex).

Women who have had difficult previous births due to posterior,   asynclitism , or a labor that didn’t progress, may want to begin bodywork and the   Forward-leaning Inversion as soon as the second trimester of pregnancy (after morning sickness is gone and extra things like fetal positioning activities can be thought about).

Here is a general guideline for the average pregnancy:

10-24 weeks gestation

This is the time when fetal position is generally determined, even though the baby’s final position isn’t typically set before 34 weeks gestation. How can this be? The body has a habit, so to speak, of how the soft tissues, ligaments, muscles, and alignment of the pelvis and whole body is set. The baby simply follows this basic pattern. By adding body balancing now, the baby has an increased chance of ideal positioning for labor at 34 weeks and beyond.

24-30 weeks

Routine   good posture   with walking and exercise will help most babies be head down as the third trimester gets underway. A 30-second inversion is good practice for everyone. Unless you have a medical reason not to, please consider the Forward-leaning Inversion. If you have a history of car accidents, falls, uncomfortable pregnancies, hormonal imbalance, or a previous breech or posterior baby, then begin the inversion and body work before or during early pregnancy.

30-34 weeks

After 30 weeks, you can start following our   6-day program for Helping Your Breech Baby   Turn . By 32-34 weeks,   chiropractic adjustments   are suggested. We recommend consulting with one of our   Spinning Babies ® Aware Practitioners . The best time to flip a breech is now.

Oxorn and Foote recommend external version at 34 weeks, but most doctors want to wait for the baby’s lungs and suck reflex to be more developed in case the maneuver goes wrong and starts labor or pulls the placenta off the uterine wall. There is often enough amniotic fluid for an easy flip before 35 weeks.

Dad’s the hero in this “over the top” support to help his mate do a Breech Tilt in the comfort of a bed!

• Breech Tilt:   Follow the FLI with the   Breech Tilt   for 10-20 minutes. This allows you to tuck your chin while upside down on a similar slanted surface. Use an ironing board against the couch, for instance.
• Open-knee Chest:   Open-knee Chest  has been studied and shown to help breeches flip. I like inversion positions that allow the mother to tuck her own chin. Myofascial workers tell me this relaxes her pelvis, whereas extending the chin tightens the pelvis.
• Professional bodywork:  Acupuncture and Moxibustion both have good statistics for flipping breeches. Find out if there’s a   Spinning Babies ® Aware Practitioner   in your area.
• Therapeutic massage:   There are muscle/fascia attachments at the base of the skull, respiratory diaphragm, inguinal ligament, and even the hip sockets! We are whole organisms, not machines with reproductive parts.
• Chiropractic or Osteopathic: Spinal adjustmentsof the neck do improve pelvic alignment, especially if accompanied by fascial release. Not all chiropractors are trained in soft tissue body work, however. And not all soft tissue work is equal. This is why we promote our Aware Practitioner Workshops for bodyworkers.

Should manual external cephalic version be done earlier?

A few midwives recommend version (manually turning the breech baby to head down) at 30 –31 weeks. Anne Frye, author of Holistic Midwifery, reported a very low incidence of breech at term when her midwifery group manually rotated babies during this gestational age.

Attempting to turn the baby now is over a month before the medical model of turning breeches. Utmost gentleness must be the protective factor. If forcing a baby to turn harms the baby or placenta, the baby is too young to be cared for outside of the Neonatal Intensive Care Unit.

Midwives who turn babies now believe there is less chance of hurting a baby and proceed very carefully, stopping at once if there is resistance. Typically, there is less resistance from the uterus because there is more fluid and the baby is still very small.

Body work is suggested before attempting this, especially for first-time moms or women who had a difficult time with their first birth. There are risks to a manual version, so the baby should be monitored closely in between each 10-30 degrees of rotation.

35-36 weeks

If your baby is breech during this time your doctor or midwife will begin to talk about how to help the baby flip head down, and possibly about scheduling a manual version for 36-37 weeks. Getting body work and having   acupuncture or homeopathy   may help soften the ligaments and a tense uterus to either help the baby flip spontaneously or to allow more success in an attempt at a version.

Moxibustion has its highest success rate this week.

36-37 weeks.

During this time, you can continue with the suggestions in the   “Professional Help”   page. Also, an obstetrician may suggest manually flipping the baby to a head down position at this time. A few midwives will also offer this, perhaps even earlier, at 30-34 weeks.

NOTE: Don’t let someone manually flip your baby without using careful monitoring of the baby’s heartbeat. Accidents can occur, even when there is good intention. The baby must be listened to and the version stopped immediately if the heart rate drops.

External cephalic version near the end of pregnancy

You may also agree to go through with a cephalic version at this time. The baby is in the womb with the cord and placenta and there is a small risk in turning the baby manually. This maneuver should be done with monitoring by experienced professionals, in a setting ready for a cesarean if needed.

There is about a 40-50% chance this will be successful. Sometimes the baby moves easily and sometimes the procedure is painful. I believe it’s important who performs it, and that ligament tightness would make this more uncomfortable. I suggest getting chiropractic, myofascial, acupuncture, homeopathy, or moxibustion (or all of these) before and after the version.

Doing the Three Sisters of Balance SM (or following the Turning Your Breech Baby guidelines) daily beforehand and just before the procedure would be relaxing and helpful. More birth professionals are using our approach in the hours or the week before the procedure and report that fewer procedures are necessary and those that are seem to be easier than average to do when the baby is able to be turned.

38-40 weeks

Sometimes a woman and her caregiver don’t know the baby is breech until this point or until labor. Rarely does a baby flip to breech this late in pregnancy but they can. Parents and providers may learn that baby is breech during a routine bio-physical ultrasound exam during this time or later in pregnancy.

An external cephalic version may yet be successful, depending on the fluid level and the flexibility of the uterus, the baby’s head position and location, a uterine septum, where the placenta is, etc.

It is still possible that the baby flips doing body balancing activities or even labor itself (contractions might be the very action that turns baby in about 1% of breeches). You may find turning easier if you keep doing the activities listed above.

40-41 weeks

Though many breeches are born about 37-39 weeks gestation, some will happily go to 41 or 42 weeks. For a head down baby, 41 weeks and 1 to 3 days is a common time for labor to begin on its own. SStarting labor at this gestation can certainly be normal for a healthy breechling, too.

If the pregnant person has a tendency to be somewhat overweight or lower energy, which can indicate low thyroid function, a longer pregnancy may be more likely. This tendency deserves looking after. Well-nourished and peppy women may also go a full pregnancy length, of course.

Going into labor and then having a planned cesarean is recommend by Dr. Michel Odent in his book, Cesarean. Going into labor spontaneously is safer for the breech vaginal birth, as well. Women who are trying to flip their baby often find it necessary to slow down the efforts and come to terms with a breech birth.

When facing a cesarean, it can be nurturing to you and your baby to plan a cesarean with skin-to-skin, delayed cord clamping, and breastfeeding on the operating room table or in the recovery room. Give yourself some time and compassion to feel your feelings and explore your options to adapt to the options you have available to you.

Postdates (after your due date) with a breech

With a breech, going all the way to 42 weeks may or may not be more of an issue. Some providers will have to end any plans for a vaginal birth by now. Midwifery statutes often limit midwifery care out of the hospital to 37-42 weeks (or 36-43, depending on where you live).

After 42 weeks, the baby’s skull bones are setting up more firmly and a vaginal birth is less favorable. I’ve been to a few breech births after 42 weeks gestation and everything went very well. But, I do sometimes wonder why labor isn’t starting and if metabolism is a reason, especially when there’s been regular bodywork for weeks.

For a person carrying a breech baby who does show signs of low thyroid function or otherwise a “sloshy” metabolism, I am inclined to transfer care to a kind hospital provider at 41.5 weeks. Intelligent and experienced monitoring may rule out issues that arise post dates that may complicate labor. With slow metabolism postdates issues with breech position may need extra attention before 42 weeks.

Continue body balancing and daily stretching but stop inversions for three days. Walk with a stride. See more at https://www.spinningbabies.com/pregnancy-birth/baby-position/breech/when-baby-flips-head-down/

If Baby Does Not Turn

Not every breech baby will turn on their own. Not every attempt at an External Cephalic Version works (It’s often 50-50). Adding body balancing has abundant anecdotal reporting to show success. But this balancing should be individualized if the pregnant person has followed general guidelines closely for 1-2 weeks without success.

Be compassionate to you and your baby. You are both doing the best you can with the resources you have.

Choose your path. Sometimes it may feel like you don’t have a choice. Consider why it feels that way. Perhaps your choice is safety over manner of birth? That’s totally valid. Just because a vaginal birth might be available to some doesn’t mean it is your first choice, too.

Sometimes babies choose, too. The labor goes too fast to do surgery for the birth. Or, the baby doesn’t come into the pelvis and surgical birth is necessary. (Remember reaching in and pulling out the baby is not reasonable if a cesarean is available in the region unless this is a second twin (subsequent triplet) or travel is impossible due to weather, war, or whatever reason. Life is real. Babies don’t follow a script. Be real with your own experience.

Inducing a breech

Inducing a breech is not recommended in out of hospital settings. Even in the hospital, the risk rises. In some areas where breech is common, Pitocin/Syntocin inductions are done with outcomes that are good enough to keep the options open. Induction by herbs is also considered out of scope for breech.

We need to respect the breech and not stress the baby, especially in settings where we don’t have the rescue setup to solve any potential problems.  Try body balancing and see if labor begins on its own. That would be a non-invasive, non-manipulating approach.

The Breech Turned During Labor

It is a rare possibility that the baby flips to head down during labor. I once assisted a midwife who’s laboring mother’s water had released. Her labor was mild and not picking up, so after 24 hours we transferred and found that the baby had flipped. The doctor thought we’d misdiagnosed, but the mother’s abdomen was so thin we could feel the baby’s knuckles and elbow and found the baby in the opposite direction after entering the hospital!

Another mother had Dynamic Body Balancing in early labor with one of Dr. Carol Phillips students who was also a midwife. Her breech baby turned head down during transition phase of labor!

Laboring With a Breech Before The Cesarean

If the plan is to have a cesarean once labor begins, call the hospital and alert them of labor immediately. Go to the hospital right away. Breech births can go quite quickly and you want to be where people are ready to help you. If you plan to have a vaginal birth, don’t delay in getting to your birth location or getting your birth team to you.

While it can be totally normal to have a 24-hour or longer breech birth, many breech labors are quite short. Because the softer bottom is first, it may take you by surprise that you are progressing with such little pain (though some breech births are as painful as head down births). Just don’t base your decision to get to the hospital on your pain level!

A cesarean can be more complicated if the baby is wedged low in the pelvis. That is why there is a recommendation to have the cesarean in early labor. But cesareans are done everyday with head down babies low in the pelvis. Sometimes it’s how it is.

Starting labor in and of itself doesn’t make the surgery more dangerous. Rushing around and doing things in a hurry might. Alert your hospital before labor and again once you start labor. Be firm that you know what you are about and that they need to get the Operating Room ready while you are on your way.

Mostly, a leisurely transition into the hospital can be sustained with a sense of humor and practicality. There can be a sense of calm while you and the staff take the steps to welcome your baby. This is your birth. Be present with how your experience unfolds.

After the birth

While the concern about breech position is during the birthing, when the baby is breech for most of the third trimester, their skull bones become shaped by the inside of the upper womb (the fundus). This isn’t typically an issue but can be noticed.

Craniosacral therapy   can gently (and without using force) reshape the baby’s head, ideally during the month or two after birth. Surgery on baby’s skull is seldom necessary after 3-6 sessions with a Craniosacral therapist. For most breech babies, this issue is not present. I list is here because I have heard some assumptions that can be dispelled.

A question about breech

Email from Wed, Feb 11, 2009:

…I’m 30 weeks and the baby is what I’d describe as   oblique   breech – his head is on my right side next to my belly button, his hips/butt are in my pelvis on the lower left side (my left) and his feet are in front of his face. I think he’s facing forward – towards my belly button. I’ve known this for weeks just because his big head is so hard I always bump that spot on accident. …. my first son was 9 lbs and born posterior, so I’m really hoping this baby is in the ideal position for delivery… so both of these things make me nervous that he won’t move. He has been in this position for a few weeks now. … Anyway, just wondering if I should worry and what, if anything, I can do to help him move now. My Midwife suggested a Chiropractor that can do some adjustments. I’d like to do the couch inversion too. Would it help for me to walk more? Also, should I sleep more on one side than the other? Thanks for your help! Great site!

Gail’s reply:

Hi…. now is a good time to take action, not so much that your baby is breech, but because your first baby was   OP . You see, a pelvic misalignment and/or round ligament spasms (they often go together) can result in either a breech or a   posterior fetal position . So, a breech will often flip to a posterior position and may stay that way unless you resolve the underlying issue. Maternal positioning is often not enough by itself to correct a posterior fetal position when there is a history of previous posterior or breech babies. While certainly most breech babies flip head down, it’s beneficial to help correct the symmetry of your   uterine ligaments   now, while the baby is still small enough to have plenty of room to flip head down once the reason for the previous posterior position is remedied. See some things a Chiropractor can do for breech and posterior by reading   Professional Help .

Breech Position: What It Means if Your Baby Is Breech

Medical review policy, latest update:.

Medically reviewed for accuracy.

What does it mean if a baby is breech?

What are the different types of breech positions, what causes a baby to be breech, recommended reading, how can you tell if your baby is in a breech position, what does it mean to turn a breech baby, how can you turn a breech baby, how does labor usually start with a breech baby.

If your cervix dilates too slowly, if your baby doesn’t move down the birth canal steadily or if other problems arise, you’ll likely have a C-section. Talk your options over with your practitioner now to be prepared. Remember that though you may feel disappointed things didn’t turn out exactly as you envisioned, these feelings will melt away once your bundle of joy safely enters the world.

What happens if your baby is breech?

Babies often twist and turn during pregnancy, but most will have moved into the head-down (also known as head-first) position by the time labour begins. However, that does not always happen, and a baby may be:

• bottom first or feet first (breech position)
• lying sideways (transverse position)

Bottom first or feet first (breech baby)

If your baby is lying bottom or feet first, they are in the breech position. If they're still breech at around 36 weeks' gestation, the obstetrician and midwife will discuss your options for a safe delivery.

Turning a breech baby

If your baby is in a breech position at 36 weeks, you'll usually be offered an external cephalic version (ECV). This is when a healthcare professional, such as an obstetrician, tries to turn the baby into a head-down position by applying pressure on your abdomen. It's a safe procedure, although it can be a bit uncomfortable.

Giving birth to a breech baby

If an ECV does not work, you'll need to discuss your options for a vaginal birth or  caesarean section  with your midwife and obstetrician.

If you plan a caesarean and then go into labour before the operation, your obstetrician will assess whether it's safe to proceed with the caesarean delivery. If the baby is close to being born, it may be safer for you to have a vaginal breech birth.

The Royal College of Obstetricians and Gynaecologists (RCOG) website has more information on what to expect if your baby is still breech at the end of pregnancy .

The RCOG advises against a vaginal breech delivery if:

• your baby's feet are below its bottom – known as a "footling breech"
• your baby is larger or smaller than average – your healthcare team will discuss this with you
• your baby is in a certain position – for example, their neck is very tilted back, which can make delivery of the head more difficult
• you have a low-lying placenta (placenta praevia)
• you have  pre-eclampsia

Lying sideways (transverse baby)

If your baby is lying sideways across the womb, they are in the transverse position. Although many babies lie sideways early on in pregnancy, most turn themselves into the head-down position by the final trimester.

Giving birth to a transverse baby

Depending on how many weeks pregnant you are when your baby is in a transverse position, you may be admitted to hospital. This is because of the very small risk of the umbilical cord coming out of your womb before your baby is born (cord prolapse). If this happens, it's a medical emergency and the baby must be delivered very quickly.

Sometimes, it's possible to manually turn the baby to a head-down position, and you may be offered this.

But, if your baby is still in the transverse position when you approach your due date or by the time labour begins, you'll most likely be advised to have a caesarean section.

Breech baby at the end of pregnancy

Published: July 2017

Please note that this information will be reviewed every 3 years after publication.

This patient information page provides advice if your baby is breech towards the end of pregnancy and the options available to you.

It may also be helpful if you are a partner, relative or friend of someone who is in this situation.

The information here aims to help you better understand your health and your options for treatment and care. Your healthcare team is there to support you in making decisions that are right for you. They can help by discussing your situation with you and answering your questions. 

This information is for you if your baby remains in the breech position after 36 weeks of pregnancy. Babies lying bottom first or feet first in the uterus (womb) instead of in the usual head-first position are called breech babies. 

This information includes:

• What breech is and why your baby may be breech
• The different types of breech
• The options if your baby is breech towards the end of your pregnancy
• What turning a breech baby in the uterus involves (external cephalic version or ECV)
• How safe ECV is for you and your baby
• Options for birth if your baby remains breech
• Other information and support available

Within this information, we may use the terms ‘woman’ and ‘women’. However, it is not only people who identify as women who may want to access this information. Your care should be personalised, inclusive and sensitive to your needs, whatever your gender identity.

A glossary of medical terms is available at  A-Z of medical terms .

• Breech is very common in early pregnancy, and by 36–37 weeks of pregnancy most babies will turn into the head-first position. If your baby remains breech, it does not usually mean that you or your baby have any problems.
• Turning your baby into the head-first position so that you can have a vaginal delivery is a safe option.
• The alternative to turning your baby into the head-first position is to have a planned caesarean section or a planned vaginal breech birth.

Babies lying bottom first or feet first in the uterus (womb) instead of in the usual head-first position are called breech babies. Breech is very common in early pregnancy, and by 36-37 weeks of pregnancy, most babies turn naturally into the head-first position.

Towards the end of pregnancy, only 3-4 in every 100 (3-4%) babies are in the breech position.

A breech baby may be lying in one of the following positions:

It may just be a matter of chance that your baby has not turned into the head-first position. However, there are certain factors that make it more difficult for your baby to turn during pregnancy and therefore more likely to stay in the breech position. These include:

• if this is your first pregnancy
• if your placenta is in a low-lying position (also known as placenta praevia); see the RCOG patient information  Placenta praevia, placenta accreta and vasa praevia
• if you have too much or too little fluid ( amniotic fluid ) around your baby
• if you are having more than one baby.

Very rarely, breech may be a sign of a problem with the baby. If this is the case, such problems may be picked up during the scan you are offered at around 20 weeks of pregnancy.

If your baby is breech at 36 weeks of pregnancy, your healthcare professional will discuss the following options with you:

• trying to turn your baby in the uterus into the head-first position by external cephalic version (ECV)
• planned caesarean section
• planned vaginal breech birth.

What does ECV involve?

ECV involves applying gentle but firm pressure on your abdomen to help your baby turn in the uterus to lie head-first.

Relaxing the muscle of your uterus with medication has been shown to improve the chances of turning your baby. This medication is given by injection before the ECV and is safe for both you and your baby. It may make you feel flushed and you may become aware of your heart beating faster than usual but this will only be for a short time.

Before the ECV you will have an ultrasound scan to confirm your baby is breech, and your pulse and blood pressure will be checked. After the ECV, the ultrasound scan will be repeated to see whether your baby has turned. Your baby’s heart rate will also be monitored before and after the procedure. You will be advised to contact the hospital if you have any bleeding, abdominal pain, contractions or reduced fetal movements after ECV.

ECV is usually performed after 36 or 37 weeks of pregnancy. However, it can be performed right up until the early stages of labour. You do not need to make any preparations for your ECV.

ECV can be uncomfortable and occasionally painful but your healthcare professional will stop if you are experiencing pain and the procedure will only last for a few minutes. If your healthcare professional is unsuccessful at their first attempt in turning your baby then, with your consent, they may try again on another day.

If your blood type is rhesus D negative, you will be advised to have an anti-D injection after the ECV and to have a blood test. See the NICE patient information  Routine antenatal anti-D prophylaxis for women who are rhesus D negative , which is available at:  www.nice.org.uk/guidance/ta156/informationforpublic .

Why turn my baby head-first?

If your ECV is successful and your baby is turned into the head-first position you are more likely to have a vaginal birth. Successful ECV lowers your chances of requiring a caesarean section and its associated risks.

Is ECV safe for me and my baby?

ECV is generally safe with a very low complication rate. Overall, there does not appear to be an increased risk to your baby from having ECV. After ECV has been performed, you will normally be able to go home on the same day.

When you do go into labour, your chances of needing an emergency caesarean section, forceps or vacuum (suction cup) birth is slightly higher than if your baby had always been in a head-down position.

Immediately after ECV, there is a 1 in 200 chance of you needing an emergency caesarean section because of bleeding from the placenta and/or changes in your baby’s heartbeat.

ECV should be carried out by a doctor or a midwife trained in ECV. It should be carried out in a hospital where you can have an emergency caesarean section if needed.

ECV can be carried out on most women, even if they have had one caesarean section before.

ECV should not be carried out if:

• you need a caesarean section for other reasons, such as placenta praevia; see the RCOG patient information  Placenta praevia, placenta accreta and vasa praevia
• you have had recent vaginal bleeding
• your baby’s heart rate tracing (also known as CTG) is abnormal
• your waters have broken
• you are pregnant with more than one baby; see the RCOG patient information  Multiple pregnancy: having more than one baby .

Is ECV always successful?

ECV is successful for about 50% of women. It is more likely to work if you have had a vaginal birth before. Your healthcare team should give you information about the chances of your baby turning based on their assessment of your pregnancy.

If your baby does not turn then your healthcare professional will discuss your options for birth (see below). It is possible to have another attempt at ECV on a different day.

If ECV is successful, there is still a small chance that your baby will turn back to the breech position. However, this happens to less than 5 in 100 (5%) women who have had a successful ECV.

There is no scientific evidence that lying down or sitting in a particular position can help your baby to turn. There is some evidence that the use of moxibustion (burning a Chinese herb called mugwort) at 33–35 weeks of pregnancy may help your baby to turn into the head-first position, possibly by encouraging your baby’s movements. This should be performed under the direction of a registered healthcare practitioner.

Depending on your situation, your choices are:

There are benefits and risks associated with both caesarean section and vaginal breech birth, and these should be discussed with you so that you can choose what is best for you and your baby.

Caesarean section

If your baby remains breech towards the end of pregnancy, you should be given the option of a caesarean section. Research has shown that planned caesarean section is safer for your baby than a vaginal breech birth. Caesarean section carries slightly more risk for you than a vaginal birth.

Caesarean section can increase your chances of problems in future pregnancies. These may include placental problems, difficulty with repeat caesarean section surgery and a small increase in stillbirth in subsequent pregnancies. See the RCOG patient information  Choosing to have a caesarean section .

If you choose to have a caesarean section but then go into labour before your planned operation, your healthcare professional will examine you to assess whether it is safe to go ahead. If the baby is close to being born, it may be safer for you to have a vaginal breech birth.

Vaginal breech birth

After discussion with your healthcare professional about you and your baby’s suitability for a breech delivery, you may choose to have a vaginal breech birth. If you choose this option, you will need to be cared for by a team trained in helping women to have breech babies vaginally. You should plan a hospital birth where you can have an emergency caesarean section if needed, as 4 in 10 (40%) women planning a vaginal breech birth do need a caesarean section. Induction of labour is not usually recommended.

While a successful vaginal birth carries the least risks for you, it carries a small increased risk of your baby dying around the time of delivery. A vaginal breech birth may also cause serious short-term complications for your baby. However, these complications do not seem to have any long-term effects on your baby. Your individual risks should be discussed with you by your healthcare team.

Before choosing a vaginal breech birth, it is advised that you and your baby are assessed by your healthcare professional. They may advise against a vaginal birth if:

• your baby is a footling breech (one or both of the baby’s feet are below its bottom)
• your baby is larger or smaller than average (your healthcare team will discuss this with you)
• your baby is in a certain position, for example, if its neck is very tilted back (hyper extended)
• you have a low-lying placenta (placenta praevia); see the RCOG patient information  Placenta Praevia, placenta accreta and vasa praevia
• you have pre-eclampsia or any other pregnancy problems; see the RCOG patient information  Pre-eclampsia .

With a breech baby you have the same choices for pain relief as with a baby who is in the head-first position. If you choose to have an epidural, there is an increased chance of a caesarean section. However, whatever you choose, a calm atmosphere with continuous support should be provided.

If you have a vaginal breech birth, your baby’s heart rate will usually be monitored continuously as this has been shown to improve your baby’s chance of a good outcome.

In some circumstances, for example, if there are concerns about your baby’s heart rate or if your labour is not progressing, you may need an emergency caesarean section during labour. A  paediatrician  (a doctor who specialises in the care of babies, children and teenagers) will attend the birth to check your baby is doing well.

If you go into labour before 37 weeks of pregnancy, the balance of the benefits and risks of having a caesarean section or vaginal birth changes and will be discussed with you.

If you are having twins and the first baby is breech, your healthcare professional will usually recommend a planned caesarean section.

If, however, the first baby is head-first, the position of the second baby is less important. This is because, after the birth of the first baby, the second baby has lots more room to move. It may turn naturally into a head-first position or a doctor may be able to help the baby to turn. See the RCOG patient information  Multiple pregnancy: having more than one baby .

If you would like further information on breech babies and breech birth, you should speak with your healthcare professional.

To determine if the common risks for breech presentation at term labor are also eligible in preterm labor.

A Finnish cross-sectional study included 737,788 singleton births (24–42 gestational weeks) during 2004–2014. A multivariable logistic regression analysis was used to calculate the risks of breech presentation.

The incidence of breech presentation at delivery decreased from 23.5% in pregnancy weeks 24–27 to 2.5% in term pregnancies. In gestational weeks 24–27, preterm premature rupture of membranes was associated with breech presentation. In 28–31 gestational weeks, breech presentation was associated with maternal pre-eclampsia/hypertension, preterm premature rupture of membranes, and fetal birth weight below the tenth percentile. In gestational weeks 32–36, the risks were advanced maternal age, nulliparity, previous cesarean section, preterm premature rupture of membranes, oligohydramnios, birth weight below the tenth percentile, female sex, and congenital anomaly. In term pregnancies, breech presentation was associated with advanced maternal age, nulliparity, maternal hypothyroidism, pre-gestational diabetes, placenta praevia, premature rupture of membranes, oligohydramnios, congenital anomaly, female sex, and birth weight below the tenth percentile.

Breech presentation in preterm labor is associated with obstetric risk factors compared to cephalic presentation. These risks decrease linearly with the gestational age. In moderate to late preterm delivery, breech presentation is a high-risk state and some obstetric risk factors are yet visible in early preterm delivery. Breech presentation in extremely preterm deliveries has, with the exception of preterm premature rupture of membranes, similar clinical risk profiles as in cephalic presentation.

Introduction

The prevalence of breech presentation at delivery decreases with increasing gestational age. At 28 pregnancy weeks, every fifth fetus lies in the breech presentation and in term pregnancies, less than 4% of all singleton fetuses are in breech presentation at delivery [ 1 , 2 ]. Most likely this is due to a lack of fetal movements [ 3 ] or an incomplete fetal rotation, since the possibility of a spontaneous rotation declines with increasing gestational age. Consequently, preterm labor itself is often associated with breech presentation at delivery, since the fetus was not yet able to rotate [ 4 – 9 ]. This fact makes preterm labor as one of the strongest risk factors for breech presentation.

Vaginal breech delivery in term pregnancies is not only associated with poorer perinatal outcomes compared to vaginal delivery with a fetus in cephalic presentation [ 6 , 10 , 11 ], but also it is debated whether the cause of breech presentation itself is a risk for adverse peri- and neonatal outcomes [ 3 , 12 , 13 ]. Several fetal and maternal features, such as fetal growth restriction, congenital anomaly, oligohydramnios, gestational diabetes, and previous cesarean section, are linked to a higher risk of breech presentation at term, and, furthermore, are associated with an increased risk for adverse perinatal outcomes [ 3 – 5 , 8 , 9 , 14 – 17 ].

The literature lacks studies on the risk factors of breech presentation in preterm pregnancies. It remains unclear whether breech presentation at preterm labor is only caused by the incomplete fetal rotation, or whether breech presentation in preterm labor is also associated with other obstetric risk factors. Most of the studies reviewing risk factors for breech presentation focus on term pregnancies. Our hypothesis is that breech presentation in preterm deliveries is, besides preterm pregnancy itself, associated with other risk factors similar to breech presentation at term. We aim to compare the risks of preterm breech presentation to those in cephalic presentation by gestational age. Such information would be valuable in the risk stratification of breech deliveries by gestational age.

Materials and methods

We conducted a retrospective population-based cross-sectional study. The population included all the singleton preterm and term births, from January 2004 to December 2014 in Finland. The data were collected from the national medical birth register and the hospital discharge register, maintained by the National Institute for Health and Welfare. All Finnish maternity hospitals are obligated to contribute clinical data on births from 22 weeks or birth weight of 500 g to the register. All newborn infants are examined by a pediatrician and given a personal identification number that can be traced in the case of perinatal mortality or morbidity. The hospital discharge register contains information on all surgical procedures and diagnoses (International Statistical Classification of Diseases and Related Health Problems 10th Revision, ICD-10) in all inpatient care and outpatient care in public hospitals.

Authorization to use the data was obtained from the National Institute for Health and Welfare as required by the national data protection law in Finland (reference number THL/652/5.05.00/2017).

The study population included all the women with a singleton fetus in breech presentation at the time of delivery. The control group included all the women with a singleton fetus in cephalic presentation at delivery. Other presentations were excluded from the study ( N  = 1671) (Fig.  1 ). Gestational age was determined according to early ultrasonographic measurement which is routinely performed in Finland and it encompasses over 95% of the mothers, or if not available, to the last menstrual period. We excluded neonates delivered before 24 weeks of gestation and birth weight of less than 500 g, because the lower viability may have influenced the mode of the delivery or the outcome. The study population was divided into four categories according to the World Health Organization (WHO) definitions of preterm and term deliveries. WHO defines preterm birth as a fetus born alive before 37 completed weeks of pregnancy. WHO recommends sub-categories of preterm birth, based on gestational age, as extremely preterm (less than 28 pregnancy weeks), very preterm (28–32 pregnancy weeks), and moderate to late preterm (32–37 pregnancy weeks).

Breech presentation for singleton pregnancies during the period of 2004–2014 in Finland

In our study, we assessed four factors that may be associated with breech presentation based on prior reports [ 3 – 5 , 14 , 17 – 20 ]. These factors were: maternal age below 25 and 35 years or more, smoking, pre-pregnancy body mass index (BMI) over 30, and in vitro fertilization. The following factors were also analyzed: nulliparity, more than three previous deliveries, and history of cesarean section. The obstetric risk factors including maternal hypo- or hyperthyroidism (ICD-10 E03, E05), gestational diabetes (ICD-10 O24.4) and other diabetes treated with insulin (ICD-10 O24.0), arterial hypertension or pre-eclampsia (ICD-10 O13, O14), and maternal care for (suspected) damage to fetus by alcohol or drugs (ICD-10 O35.4, O35.5) were assessed in the analysis. The variables that were also included in the analysis were: oligohydramnios (ICD-10 O41.0), placenta praevia (ICD-10 O44), placental abruption (ICD-10 O45), preterm premature rupture of membranes (PPROM) (ICD-10 O42), infant sex, fetal birth weight below the tenth percentile, fetuses with birth weight above the 97th percentile, and fetal congenital anomalies as defined in the register of congenital malformations.

The babies born in breech presentation from the four study groups were compared with the babies born in cephalic presentation with the equal gestational age, according to WHO classification. The calculations were performed using SPSS 19. Statistical differences in categorical variables were evaluated with the Chi-squared test or Fisher’s exact test when appropriate. We calculated odds ratios (ORs) with corresponding 95% confidence intervals (CIs) using binary logistic regression. Each study group was separately adjusted, according to gestational age at delivery, defined by WHO. The adjustment for the risk factors was done by multivariable logistic regression model for all variables. Differences were deemed to be statistically significant with P value < 0.05.

This analysis includes 737,788 singleton births, from these 20,086 were in breech presentation at the time of delivery. Out of all deliveries, 33,489 infants were born preterm. The prevalence of breech presentation at delivery decreased with the increase of the gestational age: 23.5% in extremely preterm delivery, 15.4% very preterm deliveries, and 6.7% in moderate to late preterm deliveries. At term, the prevalence of breech presentation at delivery was 2.5% (Fig.  1 ).

From all deliveries, 2056 fetuses were born extremely preterm (24 + 0 to 27 + 6 gestational weeks). The differences in the possible risk factors for breech presentation at delivery were higher odds of PPROM (aOR 1.39, 95% CI 1.08–1.79, P  = 0.010) and a lower risk of placental abruption (aOR 0.59, 95% CI 0.36–0.98, P  = 0.040). No statistically significant differences were observed for the other factors (Table ​ (Table1, 1 , Figs.  1 , ​ ,2, 2 , ​ ,3, 3 , ​ ,4 4 ).

The group of very preterm deliveries (28 + 0 to 31 + 6 gestational weeks) included 4582 singleton newborns. Breech presentation at delivery was associated with PPROM (aOR 1.61, 95% CI 1.32–1.96, P  < 0.001), oligohydramnios (aOR 1.65, 95% CI 1.03–2.64, P  = 0.038), fetal birth weight below the tenth percentile (aOR 1.57, 95% CI 1.19–2.08, P  = 0.002), and maternal pre-eclampsia and arterial hypertension (aOR 1.31, 95% CI 1.04–1.66, P  = 0.023). Details of risk factors in very preterm breech deliveries are described in Table ​ Table2. 2 . The risk of placenta praevia as well as having a birth weight above the 97th percentile was lower in pregnancies with fetuses in breech rather than in cephalic presentation (Table ​ (Table2, 2 , Figs. ​ Figs.2, 2 , ​ ,3, 3 , ​ ,4 4 ).

The moderate to late preterm delivery group (32 + 0 to 36 + 6 gestational weeks) included 26,851 deliveries. Breech presentation in moderate to late preterm deliveries was associated with older maternal age (maternal age 35 years or more aOR 1.24, 95% CI 1.10–1.39, P  < 0.001), nullipara (aOR 1.43, 95% CI 1.27–1.60, P  < 0.001), maternal BMI less than 25 (maternal BMI ≥ 25 aOR 0.75, 95% CI 0.62–0.91, P  = 0.004), previous cesarean section (aOR 1.31, 95% CI 1.12–1.53, P  < 0.001), female sex (aOR 1.22, 95% CI 1.11–1.34, P  < 0.001), congenital anomaly (aOR 1.37, 95% CI 1.22–1.55, P  < 0.001), fetal birth weight below the tenth percentile (aOR 1.31, 95% CI 1.10–1.56, P  = 0.003), oligohydramnios (aOR 3.60, 95% CI 2.63–4.92, P  < 0.001), and PPROM (aOR 1.58, 95% CI 1.41–1.78, P  < 0.001). Breech presentation decreased the odds of having a fetus with birth weight above the 97th percentile (aOR 0.60, 95% CI 0.42–0.85, P  = 0.004) (Table ​ (Table3, 3 , Figs. ​ Figs.2, 2 , ​ ,3, 3 , ​ ,4 4 ).

The term and post-term group included 704,299 deliveries, among them 17,044 fetuses in breech presentation. The factors associated with breech presentation amongst these were: maternal age of 35 years or more (aOR 1.24, 95% CI 1.19–1.29, P  < 0.001), nullipara (aOR 2.46, 95% CI 2.37–2.55, P  < 0.001), maternal BMI less than 25 (BMI ≥ 25 aOR 0.90, 95% CI 0.85–0.96, P  < 0.001), maternal hypothyroidism (aOR 1.53, 95% CI 1.28–1.82, P  < 0.001), pre-gestational diabetes treated with insulin (aOR 1.24, 95% CI 1.00–1.53, P  = 0.049), placenta praevia (aOR 1.45, 95% CI 1.11–1.91, P  = 0.007), premature rupture of membranes (PROM) (aOR 1.58, 95% CI 1.45–1.72, P  < 0.001), oligohydramnios (aOR 2.02, 95% CI 1.83–2.22, P  < 0.001), congenital anomaly (aOR 1.97, 95% CI 1.89–2.06, P  < 0.001), female sex (aOR 1.28, 95% CI 1.24–1.32, P  < 0.001), and birth weight below the tenth percentile (aOR 1.18, 95% CI 1.12–1.24, P  < 0.001) Table ​ Table4 4 includes details for risk factors of term and post-term group (Figs.  2 , ​ ,3, 3 , ​ ,4 4 ).

The main novel finding of our study was that the risk associations increase with each gestational age group after 28 weeks of gestation. With the exception of PPROM, the extremely preterm breech deliveries have similar clinical risk profiles as in cephalic presentation when matched for gestational age. However, as gestation proceeds, the risks start to cluster. In moderate to late preterm pregnancies as in term pregnancies, the breech presentation is a high-risk state being associated with several risk factors: PPROM, oligohydramnios, advanced maternal age, nulliparity, previous cesarean section, fetal birth weight below the tenth percentile, female sex, and fetal congenital anomalies. These are in line with the findings of previous studies [ 3 , 5 , 7 , 8 ], that associated breech presentation at term with obstetric risk factors. The prevalence of breech presentation was negatively correlated with the gestational age with a decline from 23.5% in extremely preterm pregnancies to 2.5% at term. The prevalence of breech presentation in preterm pregnancies observed in our trial is similar to that of comparable studies [ 1 , 2 ].

In extremely preterm deliveries, PPROM was the only risk factor for breech presentation and it stayed as a risk for breech presentation through the gestational weeks. This finding is comparable to the previous literature suggesting that PPROM occurs more often at earlier gestational age in pregnancies with the fetus in breech presentation compared with cephalic [ 21 , 22 ]. PPROM might prevent the fetus to change into cephalic presentation. Furthermore, Goodman and colleagues (2013) reported that in pregnancies with a fetus in a presentation other than cephalic had more complications such as oligohydramnios, infections, placental abruption, and even stillbirths. In our study, surprisingly, placental abruption seemed to have a negative correlation with breech presentation among extremely preterm deliveries. This inconsistency between our results and the literature might be due to the small number of cases. Many of the obstetric complications, for example gestational diabetes, late pre-eclampsia, and late intrauterine growth restriction develop during the second or the third trimester of the pregnancy which explains partially why the risk factors for breech presentation are rarer in extremely preterm deliveries.

In very preterm delivery, breech presentation was associated with PPROM, pre-eclampsia, and fetal birth weight below the tenth percentile. Fetal growth restriction is a known risk factor for breech presentation at term, since it is associated with reduced fetal movements due to diminished resources [ 23 – 25 ]. Furthermore, fetal growth restriction is known to be the single largest factor for stillbirth and neonatal mortality [ 26 – 30 ]. Maternal arterial hypertension disturbs placental function which might cause low birth weight [ 31 , 32 ]. Arterial hypertension and pre-eclampsia increased the risk for breech presentation in very preterm births, but not in earlier or later preterm pregnancies. This finding may be due to the bias that pre-eclampsia is a well-described risk factor for PPROM, fetal growth restriction, and preterm deliveries which are also independent markers for breech presentation itself [ 4 , 5 , 31 , 33 , 34 ]. The severity of early pre-eclampsia might affect the fetal wellbeing, reduce fetal movements and growth, which might reduce the spontaneous fetal rotation to the cephalic position [ 35 ]. In addition, the most severe cases might not reach older gestational age before the delivery.

The risk factor for breech presentation in moderate to late preterm breech delivery was PPROM, oligohydramnios, advanced maternal age, nulliparity, previous cesarean section, fetal birth weight below the tenth percentile, female sex, and fetal congenital anomalies. Oligohydramnios is a known significant risk factor for term breech pregnancies [ 25 ] and it is linked to the reduced fetal movements partly due to a restricted intrauterine space [ 24 , 35 ] and nuchal cords [ 35 ]. Additionally, oligohydramnios is associated with placental dysfunction, which might reduce fetal resources and thus has a progressive effect on the fetal movements and prevent the fetus from turning into cephalic presentation [ 3 , 4 , 18 ]. Fetal female sex in moderate to late preterm breech pregnancies remained as a risk factor, as identified previously for term pregnancies [ 3 – 5 ]. It has been debated whether this risk is due to a smaller fetal size or that female fetuses tend to move less [ 9 , 20 ]. The mothers of infants born in breech presentation in moderate to late preterm and term and post-term pregnancies seemed to be older and had an increased risk of having a fetus with a congenital anomaly. The advanced maternal age is associated with negative effects on vascular health, which may have an influence on the developing fetus and increase the incidence of congenital anomalies [ 19 , 34 , 36 ]. Furthermore, congenital anomalies may have a negative influence on fetal movements [ 19 , 35 ]. Whereas, the low birth weight was found as a risk for breech presentation, a birth weight above the 97th percentile was, coherently a protective factor for breech presentation in very to term and post-term pregnancies.

We found that in term pregnancies, breech presentation was associated with advanced maternal age, nulliparity, maternal hypothyroidism, pre-gestational diabetes, placenta praevia, PROM, oligohydramnios, fetal congenital anomaly, female sex of the fetus, and birth weight below the tenth percentile. A previous cesarean section is known to be positively related to the odds of having a fetus in breech presentation at term [ 5 , 14 ], and in our study, this risk factor started to show already in moderate to late preterm pregnancies. Instead of the scar being the cause of breech presentation, it is more likely that the women with a history of breech cesarean section have, during subsequent pregnancies, a fetus in breech presentation again or have a cesarean section for another reason [ 3 , 5 , 37 ]. Our data suggest that the advanced maternal age and nulliparity are the risks for breech presentation at term, but as well as in moderate to late preterm pregnancies. The tight wall of the abdomen and the uterus of nulliparous women might inhibit the fetus from rotating to cephalic presentation [ 9 ]. In a meta-analysis from 2017, older maternal age has been considered to increase the risk of placental dysfunction such as pre-eclampsia and preterm birth [ 36 ] that are also common risk factors for breech presentation [ 4 , 5 ]. Bearing the first child in older maternal age and giving birth by cesarean section may affect the decision not to have another child and might explain the higher rate of nulliparity among moderate to late preterm and term deliveries [ 1 ]. Our study found correlation between maternal hypothyroidism and breech presentation at term. Some studies have demonstrated an association between maternal thyroid hypofunction and adverse pregnancy outcomes such as pre-eclampsia and low birth weight which are, furthermore, risks for breech presentation and may explain partly the higher prevalence of maternal hypothyroidism in term breech deliveries [ 38 – 40 ]. However, the absence of screening of, for example, thyroid diseases may cause bias in the diagnoses.

Our study demonstrated that as gestation proceeds, more obstetric risk factors can be found associating with breech presentation. In the earlier gestation and excluding PPROM, breech deliveries did not differ in obstetric risk factors compared to cephalic. The risk factors in 32 weeks of gestational age are comparable to those in term pregnancy, and several of these factors, such as low birth weight, congenital anomalies and history of cesarean section, are associated with adverse fetal outcomes [ 1 , 4 , 5 , 8 , 14 , 17 ] and must be taken into account when treating breech pregnancies. Risk factors should be evaluated prior to offering a patient an external cephalic version, as the presence of some of these risks may increase the change of failed version or fetal intolerance of the procedure. This study had adequate power to show differences between the risk profiles of breech and cephalic presentations in different gestational phase. Further research, however, is needed for improving the identification of patients at risk for preterm breech labor and elucidating the optimal route for delivery in preterm breech pregnancies.

Our study is unique since it is the first study, to our knowledge, that compares the risks for breech presentation in preterm and term deliveries. The analysis is based on a large nationwide population, which is the major strength of our study. The study population included nearly 34,000 preterm births over 11 years in Finland and 737,788 deliveries overall. The medical treatment of pregnancies is homogenous, since there are no private hospitals treating deliveries. A further strength relates to the important information on the characteristics of the mother, for example smoking during pregnancy and pre-pregnancy body mass index. The retrospective approach is a limitation of the study, another one is the design as a record linkage study, due to which the variables were restricted to the data availability. Therefore, we were not able to assess, for example uterine anomalies or previous breech deliveries to the analysis.

Our results show that the factors associated with breech presentation in very late preterm breech deliveries resemble those in term pregnancies. However, breech presentation in extremely preterm breech birth has similar clinical risk profiles as in cephalic presentation.

Patient Instructions

Breech presentation refers to the baby presenting for delivery with the buttocks or feet first rather than head.

Associated with increased morbidity and mortality for the mother in terms of emergency cesarean section and placenta previa; and for the baby in terms of preterm birth, small fetal size, congenital anomalies, and perinatal mortality.

Incidence decreases as pregnancy progresses and by term occurs in 3% to 4% of singleton term pregnancies.

Treatment options include external cephalic version to increase the likelihood of vaginal birth or a planned cesarean section, the optimal gestation being 37 and 39 weeks, respectively.

Planned cesarean section is considered the safest form of delivery for infants with a persisting breech presentation at term.

Premature fetus.

Prematurity is consistently associated with breech presentation. [ 6 ] [ 9 ] This may be due to the smaller size of preterm infants, who are more likely to change their in utero position.

Increasing duration of pregnancy may allow breech-presenting fetuses time to grow, turn spontaneously or by external cephalic version, and remain cephalic-presenting.

Larger fetuses may be forced into a cephalic presentation in late pregnancy due to space or alignment constraints within the uterus.

Low birth-weight is a risk factor for breech presentation. [ 9 ] [ 11 ] [ 12 ] [ 13 ] [ 14 ] Term breech births are associated with a smaller fetal size for gestational age, highlighting the association with low birth-weight rather than prematurity. [ 6 ]

nulliparity

Women having a first birth have increased rates of breech presentation, probably due to the increased likelihood of smaller fetal size. [ 6 ] [ 9 ]

Relaxation of the uterine wall in multiparous women may reduce the odds of breech birth and contribute to a higher spontaneous or external cephalic version rate. [ 10 ]

fetal congenital anomalies

Congenital anomalies in the fetus may result in a small fetal size or inappropriate fetal growth. [ 9 ] [ 12 ] [ 14 ] [ 15 ]

Anencephaly, hydrocephaly, Down syndrome, and fetal neuromuscular dysfunction are associated with breech presentation, the latter due to its effect on the quality of fetal movements. [ 9 ] [ 14 ]

previous breech delivery

The risk of recurrent breech delivery is 8%, the risk increasing from 4% after one breech delivery to 28% after three. [ 16 ]

The effects of recurrence may be due to recurring specific causal factors, either genetic or environmental in origin.

uterine abnormalities

Women with uterine abnormalities have a high incidence of breech presentation. [ 14 ] [ 17 ] [ 18 ] [ 19 ]

female fetus

Fifty-four percent of breech-presenting fetuses are female. [ 14 ]

abnormal amniotic fluid volume

Both oligohydramnios and polyhydramnios are associated with breech presentation. [ 1 ] [ 12 ] [ 14 ]

Low amniotic fluid volume decreases the likelihood of a fetus turning to a cephalic position; an increased amniotic fluid volume may facilitate frequent change in position.

placental abnormalities

An association between placental implantation in the cornual-fundal region and breech presentation has been reported, although some studies have not found it a risk factor. [ 8 ] [ 20 ] [ 21 ] [ 22 ] [ 10 ] [ 14 ]

The association with placenta previa is also inconsistent. [ 8 ] [ 9 ] [ 22 ] Placenta previa is associated with preterm birth and may be an indirect risk factor.

Pelvic or vaginal examination reveals the buttocks and/or feet, felt as a yielding, irregular mass, as the presenting part. [ 26 ] In cephalic presentation, a hard, round, regular fetal head can be palpated. [ 26 ]

The Leopold maneuver on examination suggests breech position by palpation of the fetal head under the costal margin. [ 26 ]

The baby's heartbeat should be auscultated using a Pinard stethoscope or a hand-held Doppler to indicate the position of the fetus. The fetal heartbeat lies above the maternal umbilicus in breech presentation. [ 1 ]

Tenderness under one or other costal margin as a result of pressure by the harder fetal head.

Pain due to fetal kicks in the maternal pelvis or bladder.

breech position

Visualizes the fetus and reveals its position.

Used to confirm a clinically suspected breech presentation. [ 28 ]

Should be performed by practitioners with appropriate skills in obstetric ultrasound.

Establishes the type of breech presentation by imaging the fetal femurs and their relationship to the distal bones.

Transverse lie

Differentiating Signs/Symptoms

Fetus lies horizontally across the uterus with the shoulder as the presenting part.

Similar predisposing factors such as placenta previa, abnormal amniotic fluid volume, and uterine anomalies, although more common in multiparity. [ 1 ] [ 2 ] [ 29 ]

Differentiating Tests

Clinical examination and fetal auscultation may be indicative.

Ultrasound confirms presentation.

Treatment Approach

Breech presentation <37 weeks' gestation.

The UK Royal College of Obstetricians and Gynaecologists (RCOG) recommends that corticosteroids should be offered to women between 24 and 34+6 weeks' gestation, in whom imminent preterm birth is anticipated. Corticosteroids should only be considered after discussion of risks/benefits at 35 to 36+6 weeks. Given within 7 days of preterm birth, corticosteroids may reduce perinatal and neonatal death and respiratory distress syndrome. [ 32 ] The American College of Obstetricians and Gynecologists (ACOG) recommends a single course of corticosteroids for pregnant women between 24 and 33+6 weeks' gestation who are at risk of preterm delivery within 7 days, including those with ruptured membranes and multiple gestations. It may also be considered for pregnant women starting at 23 weeks' gestation who are at risk of preterm delivery within 7 days. A single course of betamethasone is recommended for pregnant women between 34 and 36+6 weeks' gestation at risk of preterm birth within 7 days, and who have not received a previous course of prenatal corticosteroids. Regularly scheduled repeat courses or serial courses (more than two) are not currently recommended. A single repeat course of prenatal corticosteroids should be considered in women who are less than 34 weeks' gestation, who are at risk of preterm delivery within 7 days, and whose prior course of prenatal corticosteroids was administered more than 14 days previously. Rescue course corticosteroids could be provided as early as 7 days from the prior dose, if indicated by the clinical scenario. [ 33 ]

Magnesium sulfate given before anticipated early preterm birth reduces the risk of cerebral palsy in surviving infants. Physicians electing to use magnesium sulfate for fetal neuroprotection should develop specific guidelines regarding inclusion criteria, treatment regimens, and concurrent tocolysis. [ 34 ]

Breech presentation from 37 weeks' gestation, before labor

ECV is the initial treatment for a breech presentation at term when the patient is not in labor. It involves turning a fetus presenting by the breech to a cephalic (head-down) presentation to increase the likelihood of vaginal birth. [ 35 ] [ 36 ] Where available, it should be offered to all women in late pregnancy, by an experienced clinician, in hospitals with facilities for emergency delivery, and no contraindications to the procedure. [ 35 ] There is no upper time limit on the appropriate gestation for ECV, with success reported at 42 weeks.

There is no general consensus on contraindications to ECV. Contraindications include multiple pregnancy (except after delivery of a first twin), ruptured membranes, current or recent (<1 week) vaginal bleeding, rhesus isoimmunization, other indications for cesarean section (e.g., placenta previa or uterine malformation), or abnormal electronic fetal monitoring. [ 35 ] One systematic review of relative contraindications for ECV highlighted that most contraindications do not have clear empirical evidence. Exceptions include placental abruption, severe preeclampsia/HELLP syndrome, or signs of fetal distress (abnormal cardiotocography and/or Doppler flow). [ 36 ]

The procedure involves applying external pressure and firmly pushing or palpating the mother's abdomen to coerce the fetus to somersault (either forward or backward) into a cephalic position. [ 37 ]

The overall ECV success rate varies but, in a large series, 47% of women following an ECV attempt had a cephalic presentation at birth. [ 35 ] [ 38 ]  Various factors influence the success rate. One systematic review found ECV success rates to be 68% overall, with the rate significantly higher for women from African countries (89%) compared with women from non-African countries (62%), and higher among multiparous (78%) than nulliparous women (48%). [ 39 ] Overall, the ECV success rates for nulliparous and multiparous non-African women were 43% and 73%, respectively, while for nulliparous and multiparous African women rates were 79% and 91%, respectively. Another study reported no difference in success rate or rate of cesarean section among women with previous cesarean section undergoing ECV compared with women with previous vaginal birth. However, numbers were small and further studies in this regard are required. [ 40 ]

Women's preference for vaginal delivery is a major contributing factor in their decision for ECV. However, studies suggest women with a breech presentation at term may not receive complete and/or evidence-based information about the benefits and risks of ECV. [ 41 ] [ 42 ] Although up to 60% of women reported ECV to be painful, the majority highlighted the benefits outweigh the risks (71%) and would recommend ECV to their friends or be willing to repeat for themselves (84%). [ 41 ] [ 42 ]

Cardiotocography and ultrasound should be performed before and after the procedure. Tocolysis should be used to facilitate the maneuver, and Rho(D) immune globulin should be administered to women who are Rhesus negative. [ 35 ] Tocolytic agents include adrenergic beta-2 receptor stimulants such as albuterol, terbutaline, or ritodrine (widely used with ECV in some countries, but not yet available in the US). One Cochrane review of tocolytic beta stimulants demonstrates that these are less likely to be associated with failed ECV, and are effective in increasing cephalic presentation and reducing cesarean section. [ 43 ] There is no current evidence to recommend one beta-2 adrenergic receptor agonist over another. Until these data are available, adherence to a local protocol for tocolysis is recommended. The Food and Drug Administration has issued a warning against using injectable terbutaline beyond 48 to 72 hours, or acute or prolonged treatment with oral terbutaline, in pregnant women for the prevention or prolonged treatment of preterm labor, due to potential serious maternal cardiac adverse effects and death. [ 44 ] Whether this warning applies to the subcutaneous administration of terbutaline in ECV is still unclear; however, studies currently support this use. The European Medicines Agency (EMA) recommends that injectable beta agonists should be used for up to 48 hours between the 22nd and 37th week of pregnancy only. They should be used under specialist supervision with continuous monitoring of the mother and unborn baby owing to the risk of adverse cardiovascular effects in both the mother and baby. The EMA no longer recommends oral or rectal formulations for obstetric indications. [ 45 ]

If ECV is successful, pregnancy care should continue as usual for any cephalic presentation. One systematic review assessing the mode of delivery after a successful ECV found that these women were at increased risk for cesarean section and instrumental vaginal delivery compared with women with spontaneous cephalic pregnancies. However, they still had a lower rate of cesarean section following ECV (i.e., 47%) compared with the cesarean section rate for those with a persisting breech (i.e., 85%). With a number needed to treat of three, ECV is still considered to be an effective means of preventing the need for cesarean section. [ 46 ]

Planned cesarean section should be offered as the safest mode of delivery for the baby, even though it carries a small increase in serious immediate maternal complications compared with vaginal birth. [ 24 ] [ 25 ] [ 31 ] In the US, most unsuccessful ECV with persistent breech will be delivered via cesarean section.

A vaginal mode of delivery may be considered by some clinicians as an option, particularly when maternal request is provided, senior and experienced staff are available, there is no absolute contraindication to vaginal birth (e.g., placenta previa, compromised fetal condition), and with optimal fetal growth (estimated weight above the tenth centile and up to 3800 g). Other factors that make planned vaginal birth higher risk include hyperextended neck on ultrasound and footling presentation. [ 24 ]

Breech presentation from 37 weeks' gestation, during labor

The first option should be a planned cesarean section.

There is a small increase in the risk of serious immediate maternal complications compared with vaginal birth (RR 1.29, 95% CI 1.03 to 1.61), including pulmonary embolism, infection, bleeding, damage to the bladder and bowel, slower recovery from the delivery, longer hospitalization, and delayed bonding and breast-feeding. [ 23 ] [ 31 ] [ 47 ] [ 48 ] [ 49 ] [ 50 ] [ 51 ] [ 52 ] [ 53 ] [ 54 ] [ 55 ] [ 56 ] [ 57 ] [ 58 ] Consider using antimicrobial triclosan-coated sutures for wound closure to reduce the risk of surgical site infection. [ 59 ]

The long-term risks include potential compromise of future obstetric performance, increased risk of repeat cesarean section, infertility, uterine rupture, placenta accreta, placental abruption, and emergency hysterectomy. [ 60 ] [ 61 ] [ 62 ] [ 63 ]

Planned cesarean section is safer for babies, but is associated with increased neonatal respiratory distress. The risk is reduced when the section is performed at 39 weeks' gestation. [ 64 ] [ 65 ] [ 66 ] For women undergoing a planned cesarean section, RCOG recommends an informed discussion about the potential risks and benefits of a course of prenatal corticosteroids between 37 and 38+6 weeks' gestation. Although prenatal corticosteroids may reduce admission to the neonatal unit for respiratory morbidity, it is uncertain if there is any reduction in respiratory distress syndrome, transient tachypnea of the newborn, or neonatal unit admission overall. In addition, prenatal corticosteroids may result in harm to the neonate, including hypoglycemia and potential developmental delay. [ 32 ] ACOG does not recommend corticosteroids in women >37 weeks' gestation. [ 33 ]

Undiagnosed breech in labor generally results in cesarean section after the onset of labor, higher rates of emergency cesarean section associated with the least favorable maternal outcomes, a greater likelihood of cord prolapse, and other poor infant outcomes. [ 23 ] [ 67 ] [ 49 ] [ 68 ] [ 69 ] [ 70 ] [ 71 ]

This mode of delivery may be considered by some clinicians as an option for women who are in labor, particularly when delivery is imminent. Vaginal breech delivery may also be considered, where suitable, when delivery is not imminent, maternal request is provided, senior and experienced staff are available, there is no absolute contraindication to vaginal birth (e.g., placenta previa, compromised fetal condition), and with optimal fetal growth (estimated weight above the tenth centile and up to 3800 g). Other factors that make planned vaginal birth higher risk include hyperextended neck on ultrasound and footling presentation. [ 24 ]

Findings from one systematic review of 27 observational studies revealed that the absolute risks of perinatal mortality, fetal neurologic morbidity, birth trauma, 5-minute Apgar score <7, and neonatal asphyxia in the planned vaginal delivery group were low at 0.3%, 0.7%, 0.7%, 2.4%, and 3.3%, respectively. However, the relative risks of perinatal mortality and morbidity were 2- to 5-fold higher in the planned vaginal than in the planned cesarean delivery group. Authors recommend ongoing judicious decision-making for vaginal breech delivery for selected singleton, term breech babies. [ 72 ]

ECV may also be considered an option for women with breech presentation in early labor, when delivery is not imminent, provided that the membranes are intact.

A woman presenting with a breech presentation <37 weeks is an area of clinical controversy. Optimal mode of delivery for preterm breech has not been fully evaluated in clinical trials, and the relative risks for the preterm infant and mother remain unclear. In the absence of good evidence, if diagnosis of breech presentation prior to 37 weeks' gestation is made, prematurity and clinical circumstances should determine management and mode of delivery.

Primary Options

12 mg intramuscularly every 24 hours for 2 doses

6 mg intramuscularly every 12 hours for 4 doses

The UK Royal College of Obstetricians and Gynaecologists recommends that corticosteroids should be offered to women between 24 and 34+6 weeks' gestation, in whom imminent preterm birth is anticipated. Corticosteroids should only be considered after discussion of risks/benefits at 35 to 36+6 weeks. Given within 7 days of preterm birth, corticosteroids may reduce perinatal and neonatal death and respiratory distress syndrome. [ 32 ]

The American College of Obstetricians and Gynecologists recommends a single course of corticosteroids for pregnant women between 24 and 33+6 weeks' gestation who are at risk of preterm delivery within 7 days, including those with ruptured membranes and multiple gestations. It may also be considered for pregnant women starting at 23 weeks' gestation who are at risk of preterm delivery within 7 days. A single course of betamethasone is recommended for pregnant women between 34 and 36+6 weeks' gestation at risk of preterm birth within 7 days, and who have not received a previous course of prenatal corticosteroids. Regularly scheduled repeat courses or serial courses (more than two) are not currently recommended. A single repeat course of prenatal corticosteroids should be considered in women who are less than 34 weeks' gestation, who are at risk of preterm delivery within 7 days, and whose prior course of prenatal corticosteroids was administered more than 14 days previously. Rescue course corticosteroids could be provided as early as 7 days from the prior dose, if indicated by the clinical scenario. [ 33 ]

consult specialist for guidance on dose

external cephalic version (ECV)

There is no upper time limit on the appropriate gestation for ECV; it should be offered to all women in late pregnancy by an experienced clinician in hospitals with facilities for emergency delivery and no contraindications to the procedure. [ 35 ] [ 36 ]

ECV involves applying external pressure and firmly pushing or palpating the mother's abdomen to coerce the fetus to somersault (either forward or backward) into a cephalic position. [ 37 ]

There is no general consensus on contraindications to ECV. Contraindications include multiple pregnancy (except after delivery of a first twin), ruptured membranes, current or recent (<1 week) vaginal bleeding, rhesus isoimmunization, other indications for cesarean section (e.g., placenta previa or uterine malformation), or abnormal electronic fetal monitoring. [ 35 ]  One systematic review of relative contraindications for ECV highlighted that most contraindications do not have clear empirical evidence. Exceptions include placental abruption, severe preeclampsia/HELLP syndrome, or signs of fetal distress (abnormal cardiotocography and/or Doppler flow). [ 36 ]

Cardiotocography and ultrasound should be performed before and after the procedure.

If ECV is successful, pregnancy care should continue as usual for any cephalic presentation. A systematic review assessing the mode of delivery after a successful ECV found that these women were at increased risk for cesarean section and instrumental vaginal delivery compared with women with spontaneous cephalic pregnancies. However, they still had a lower rate of cesarean section following ECV (i.e., 47%) compared with the cesarean section rate for those with a persisting breech (i.e., 85%). With a number needed to treat of 3, ECV is still considered to be an effective means of preventing the need for cesarean section. [ 46 ]

tocolytic agents

see local specialist protocol for dosing guidelines

Tocolytic agents include adrenergic beta-2 receptor stimulants such as albuterol, terbutaline, or ritodrine (widely used with external cephalic version [ECV] in some countries, but not yet available in the US). They are used to delay or inhibit labor and increase the success rate of ECV. There is no current evidence to recommend one beta-2 adrenergic receptor agonist over another. Until these data are available, adherence to a local protocol for tocolysis is recommended.

The Food and Drug Administration has issued a warning against using injectable terbutaline beyond 48-72 hours, or acute or prolonged treatment with oral terbutaline, in pregnant women for the prevention or prolonged treatment of preterm labor, due to potential serious maternal cardiac adverse effects and death. [ 44 ] Whether this warning applies to the subcutaneous administration of terbutaline in ECV is still unclear; however, studies currently support this use. The European Medicines Agency (EMA) recommends that injectable beta agonists should be used for up to 48 hours between the 22nd and 37th week of pregnancy only. They should be used under specialist supervision with continuous monitoring of the mother and unborn baby owing to the risk of adverse cardiovascular effects in both the mother and baby. The EMA no longer recommends oral or rectal formulations for obstetric indications. [ 45 ]

A systematic review found there was no evidence to support the use of nifedipine for tocolysis. [ 73 ]

There is insufficient evidence to evaluate other interventions to help ECV, such as fetal acoustic stimulation in midline fetal spine positions, or epidural or spinal analgesia. [ 43 ]

Rho(D) immune globulin

300 micrograms intramuscularly as a single dose

Nonsensitized Rh-negative women should receive Rho(D) immune globulin. [ 35 ]

The indication for its administration is to prevent rhesus isoimmunization, which may affect subsequent pregnancy outcomes.

Rho(D) immune globulin needs to be given at the time of external cephalic version and should be given again postpartum to those women who give birth to an Rh-positive baby. [ 74 ]

It is best administered as soon as possible after the procedure, usually within 72 hours.

Dose depends on brand used. Dose given below pertains to most commonly used brands. Consult specialist for further guidance on dose.

elective cesarean section/vaginal breech delivery

Mode of delivery (cesarean section or vaginal breech delivery) should be based on the experience of the attending clinician, hospital policies, maternal request, and the presence or absence of complicating factors. In the US, most unsuccessful external cephalic version (ECV) with persistent breech will be delivered via cesarean section.

Cesarean section, at 39 weeks or greater, has been shown to significantly reduce perinatal mortality and neonatal morbidity compared with vaginal breech delivery (RR 0.33, 95% CI 0.19 to 0.56). [ 31 ] Although safer for these babies, there is a small increase in serious immediate maternal complications compared with vaginal birth (RR 1.29, 95% CI 1.03 to 1.61), as well as long-term risks for future pregnancies, including pulmonary embolism, bleeding, infection, damage to the bladder and bowel, slower recovery from the delivery, longer hospitalization, and delayed bonding and breast-feeding. [ 23 ] [ 31 ] [ 47 ] [ 48 ] [ 49 ] [ 50 ] [ 51 ] [ 52 ] [ 53 ] [ 54 ] [ 55 ] [ 56 ] [ 57 ] [ 58 ] Consider using antimicrobial triclosan-coated sutures for wound closure to reduce the risk of surgical site infection. [ 59 ]

Vaginal delivery may be considered by some clinicians as an option, particularly when maternal request is provided, when senior and experienced staff are available, when there is no absolute contraindication to vaginal birth (e.g., placenta previa, compromised fetal condition), and with optimal fetal growth (estimated weight above the tenth centile and up to 3800 g). Other factors that make planned vaginal birth higher risk include hyperextended neck on ultrasound and footling presentation. [ 24 ]

For women undergoing a planned cesarean section, the UK Royal College of Obstetricians and Gynaecologists recommends an informed discussion about the potential risks and benefits of a course of prenatal corticosteroids between 37 and 38+6 weeks' gestation. Although prenatal corticosteroids may reduce admission to the neonatal unit for respiratory morbidity, it is uncertain if there is any reduction in respiratory distress syndrome, transient tachypnea of the newborn, or neonatal unit admission overall. In addition, prenatal corticosteroids may result in harm to the neonate, including hypoglycemia and potential developmental delay. [ 32 ] The American College of Obstetricians and Gynecologists does not recommend corticosteroids in women >37 weeks' gestation. [ 33 ]

It is best administered as soon as possible after delivery, usually within 72 hours.

Administration of postpartum Rho (D) immune globulin should not be affected by previous routine prenatal prophylaxis or previous administration for a potentially sensitizing event. [ 74 ]

≥37 weeks' gestation in labor: no imminent delivery

planned cesarean section

For women with breech presentation in labor, planned cesarean section at 39 weeks or greater has been shown to significantly reduce perinatal mortality and neonatal morbidity compared with vaginal breech delivery (RR 0.33, 95% CI 0.19 to 0.56). [ 31 ]

Although safer for these babies, there is a small increase in serious immediate maternal complications compared with vaginal birth (RR 1.29, 95% CI 1.03 to 1.61), as well as long-term risks for future pregnancies, including pulmonary embolism, infection, bleeding, damage to the bladder and bowel, slower recovery from the delivery, longer hospitalization, and delayed bonding and breast-feeding. [ 23 ] [ 31 ] [ 47 ] [ 48 ] [ 49 ] [ 50 ] [ 51 ] [ 52 ] [ 53 ] [ 54 ] [ 55 ] [ 56 ] [ 57 ] [ 58 ]  Consider using antimicrobial triclosan-coated sutures for wound closure to reduce the risk of surgical site infection. [ 59 ]

Continuous cardiotocography monitoring should continue until delivery. [ 24 ] [ 25 ]

vaginal breech delivery

Mode of delivery (cesarean section or vaginal breech delivery) should be based on the experience of the attending clinician, hospital policies, maternal request, and the presence or absence of complicating factors.

This mode of delivery may be considered by some clinicians as an option, particularly when maternal request is provided, when senior and experienced staff are available, when there is no absolute contraindication to vaginal birth (e.g., placenta previa, compromised fetal condition), and with optimal fetal growth (estimated weight above the tenth centile and up to 3800 g). Other factors that make planned vaginal birth higher risk include hyperextended neck on ultrasound and footling presentation. [ 24 ]

For women with persisting breech presentation, planned cesarean section has, however, been shown to significantly reduce perinatal mortality and neonatal morbidity compared with vaginal breech delivery (RR 0.33, 95% CI 0.19 to 0.56). [ 31 ]

ECV may also be considered an option for women with breech presentation in early labor, provided that the membranes are intact.

There is no upper time limit on the appropriate gestation for ECV. [ 35 ]

Involves applying external pressure and firmly pushing or palpating the mother's abdomen to coerce the fetus to somersault (either forward or backward) into a cephalic position. [ 37 ]

Relative contraindications include placental abruption, severe preeclampsia/HELLP syndrome, and signs of fetal distress (abnormal cardiotocography and/or abnormal Doppler flow). [ 35 ] [ 36 ]

Rho(D) immune globulin needs to be given at the time of ECV and should be given again postpartum to those women who give birth to an Rh-positive baby. [ 74 ]

≥37 weeks' gestation in labor: imminent delivery

cesarean section

For women with persistent breech presentation, planned cesarean section has been shown to significantly reduce perinatal mortality and neonatal morbidity compared with vaginal breech delivery (RR 0.33, 95% CI 0.19 to 0.56). [ 31 ] Although safer for these babies, there is a small increase in serious immediate maternal complications compared with vaginal birth (RR 1.29, 95% CI 1.03 to 1.61), as well as long-term risks for future pregnancies, including pulmonary embolism, infection, bleeding, damage to the bladder and bowel, slower recovery from the delivery, longer hospitalization, and delayed bonding and breast-feeding. [ 23 ] [ 31 ] [ 47 ] [ 48 ] [ 49 ] [ 50 ] [ 51 ] [ 52 ] [ 53 ] [ 54 ] [ 55 ] [ 56 ] [ 57 ] [ 58 ]  Consider using antimicrobial triclosan-coated sutures for wound closure to reduce the risk of surgical site infection. [ 59 ]

This mode of delivery may be considered by some clinicians as an option, particularly when delivery is imminent, maternal request is provided, when senior and experienced staff are available, when there is no absolute contraindication to vaginal birth (e.g., placenta previa, compromised fetal condition), and with optimal fetal growth (estimated weight above the tenth centile and up to 3800 g). Other factors that make planned vaginal birth higher risk include hyperextended neck on ultrasound and footling presentation. [ 24 ]

It is best administered as soon as possible after the delivery, usually within 72 hours.

External cephalic version before term

Moxibustion, postural management, follow-up overview, perinatal complications.

Compared with cephalic presentation, persistent breech presentation has increased frequency of cord prolapse, abruptio placentae, prelabor rupture of membranes, perinatal mortality, fetal distress (heart rate <100 bpm), preterm delivery, lower fetal weight. [ 10 ] [ 11 ] [ 67 ]

complications of cesarean section

There is a small increase in the risk of serious immediate maternal complications compared with vaginal birth (RR 1.29, 95% CI 1.03 to 1.61), including pulmonary embolism, infection, bleeding, damage to the bladder and bowel, slower recovery from the delivery, longer hospitalization, and delayed bonding and breast-feeding. [ 23 ] [ 31 ] [ 47 ] [ 48 ] [ 49 ] [ 50 ] [ 51 ] [ 52 ] [ 53 ] [ 54 ] [ 55 ] [ 56 ] [ 57 ] [ 58 ]

The long-term risks include potential compromise of future obstetric performance, increased risk of repeat cesarean section, infertility, uterine rupture, placenta accreta, placental abruption, and emergency hysterectomy. [ 60 ] [ 61 ] [ 62 ] [ 63 ] The evidence suggests that using sutures, rather than staples, for wound closure after cesarean section reduces the incidence of wound dehiscence. [ 59 ]

Emergency cesarean section, compared with planned cesarean section, has demonstrated a higher risk of severe obstetric morbidity, intra-operative complications, postoperative complications, infection, blood loss >1500 mL, fever, pain, tiredness, and breast-feeding problems. [ 23 ] [ 48 ] [ 50 ] [ 70 ] [ 81 ]
