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.

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.

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

Variations in Fetal Position and Presentation |

During pregnancy, the fetus can be positioned in many different ways inside the mother's uterus. The fetus may be head up or down or facing the mother's back or front. At first, the fetus can move around easily or shift position as the mother moves. Toward the end of the pregnancy the fetus is larger, has less room to move, and stays in one position. How the fetus is positioned has an important effect on delivery and, for certain positions, a cesarean delivery is necessary. There are medical terms that describe precisely how the fetus is positioned, and identifying the fetal position helps doctors to anticipate potential difficulties during labor and delivery.

Presentation refers to the part of the fetus’s body that leads the way out through the birth canal (called the presenting part). Usually, the head leads the way, but sometimes the buttocks (breech presentation), shoulder, or face leads the way.

Position refers to whether the fetus is facing backward (occiput anterior) or forward (occiput posterior). The occiput is a bone at the back of the baby's head. Therefore, facing backward is called occiput anterior (facing the mother’s back and facing down when the mother lies on her back). Facing forward is called occiput posterior (facing toward the mother's pubic bone and facing up when the mother lies on her back).

Lie refers to the angle of the fetus in relation to the mother and the uterus. Up-and-down (with the baby's spine parallel to mother's spine, called longitudinal) is normal, but sometimes the lie is sideways (transverse) or at an angle (oblique).

For these aspects of fetal positioning, the combination that is the most common, safest, and easiest for the mother to deliver is the following:

Head first (called vertex or cephalic presentation)

Facing backward (occiput anterior position)

Spine parallel to mother's spine (longitudinal lie)

Neck bent forward with chin tucked

Arms folded across the chest

If the fetus is in a different position, lie, or presentation, labor may be more difficult, and a normal vaginal delivery may not be possible.

Variations in fetal presentation, position, or lie may occur when

The fetus is too large for the mother's pelvis (fetopelvic disproportion).

The uterus is abnormally shaped or contains growths such as fibroids .

The fetus has a birth defect .

There is more than one fetus (multiple gestation).

Position and Presentation of the Fetus

Variations in fetal position and presentation.

Some variations in position and presentation that make delivery difficult occur frequently.

Occiput posterior position

In occiput posterior position (sometimes called sunny-side up), the fetus is head first (vertex presentation) but is facing forward (toward the mother's pubic bone—that is, facing up when the mother lies on her back). This is a very common position that is not abnormal, but it makes delivery more difficult than when the fetus is in the occiput anterior position (facing toward the mother's spine—that is facing down when the mother lies on her back).

When a fetus faces up, the neck is often straightened rather than bent,which requires more room for the head to pass through the birth canal. Delivery assisted by a vacuum device or forceps or cesarean delivery may be necessary.

Breech presentation

In breech presentation, the baby's buttocks or sometimes the feet are positioned to deliver first (before the head).

When delivered vaginally, babies that present buttocks first are more at risk of injury or even death than those that present head first.

The reason for the risks to babies in breech presentation is that the baby's hips and buttocks are not as wide as the head. Therefore, when the hips and buttocks pass through the cervix first, the passageway may not be wide enough for the head to pass through. In addition, when the head follows the buttocks, the neck may be bent slightly backwards. The neck being bent backward increases the width required for delivery as compared to when the head is angled forward with the chin tucked, which is the position that is easiest for delivery. Thus, the baby’s body may be delivered and then the head may get caught and not be able to pass through the birth canal. When the baby’s head is caught, this puts pressure on the umbilical cord in the birth canal, so that very little oxygen can reach the baby. Brain damage due to lack of oxygen is more common among breech babies than among those presenting head first.

In a first delivery, these problems may occur more frequently because a woman’s tissues have not been stretched by previous deliveries. Because of risk of injury or even death to the baby, cesarean delivery is preferred when the fetus is in breech presentation, unless the doctor is very experienced with and skilled at delivering breech babies or there is not an adequate facility or equipment to safely perform a cesarean delivery.

Breech presentation is more likely to occur in the following circumstances:

Labor starts too soon (preterm labor).

The uterus is abnormally shaped or contains abnormal growths such as fibroids .

Toward the end of pregnancy, your baby will start to get into position for delivery, with their head pointed down toward the vagina. This is otherwise known as vertex presentation. However, some babies turn inside the womb so that their feet or buttocks are poised to be delivered first, which is commonly referred to as breech presentation, or a breech baby.

As you near the end of your pregnancy journey, an OB-GYN or health care provider will check your baby's positioning. You might find yourself wondering: What causes breech presentation? Are there risks involved? And how are breech babies delivered? We turned to experts and research to answer some of the most common questions surrounding breech presentation, along with what causes this positioning in the first place.

During your pregnancy, your baby constantly moves around the uterus. Indeed, most babies do somersaults up until the 36th week of pregnancy , when they pick their final position in the womb, says Laura Riley , MD, an OB-GYN in New York City. Approximately 3-4% of babies end up “upside-down” in breech presentation, with their feet or buttocks near the cervix.

Breech presentation is typically diagnosed during a visit to an OB-GYN, midwife, or health care provider. Your physician can feel the position of your baby's head through your abdominal wall—or they can conduct a vaginal exam if your cervix is open. A suspected breech presentation should ultimately be confirmed via an ultrasound, after which you and your provider would have a discussion about delivery options, potential issues, and risks.

There are three types of breech babies: frank, footling, and complete. Learn about the differences between these breech presentations.

Frank Breech

With frank breech presentation, your baby’s bottom faces the cervix and their legs are straight up. This is the most common type of breech presentation.

Footling Breech

Like its name suggests, a footling breech is when one (single footling) or both (double footling) of the baby's feet are in the birth canal, where they’re positioned to be delivered first .

Complete Breech

In a complete breech presentation, baby’s bottom faces the cervix. Their legs are bent at the knees, and their feet are near their bottom. A complete breech is the least common type of breech presentation.

Review question

What is the most effective way of managing a longitudinal lie fetal malpresentation (breech presentation) in late pregnancy?

Introduction

Breech presentation of the fetus in late pregnancy may result in prolonged or obstructed labour with resulting risks to both woman and fetus. Interventions to correct breech presentation (to cephalic) before labour and birth are important for the woman’s and the baby’s health. The aim of this review is to determine the most effective way of managing a breech presentation in late pregnancy.

The committee’s discussion of the evidence

Interpreting the evidence, the outcomes that matter most.

Provision of antenatal care is important for the health and wellbeing of both mother and baby with the aim of avoiding adverse pregnancy outcomes and enhancing maternal satisfaction and wellbeing. Breech presentation in labour may be associated with adverse outcomes for the fetus, which has contributed to an increased likelihood of caesarean birth. The committee therefore agreed that cephalic presentation in labour and method of birth were critical outcomes for the woman, and admission to SCBU/NICU, fetal death after 36 +0 weeks gestation, and infant death up to 4 weeks chronological age were critical outcomes for the baby. Apgar score <7 at 5 minutes and birth before 39 +0 weeks of gestation were important outcomes for the baby.

The quality of the evidence

The quality of the evidence for interventions for managing a longitudinal lie fetal malpresentation (that is breech presentation) in late pregnancy ranged from very low to high, with most of the evidence being of a very low or low quality.

This was predominately due to serious overall risk of bias in some outcomes; imprecision around the effect estimate in some outcomes; indirect population in some outcomes; and the presence of serious heterogeneity in some outcomes, which was unresolved by subgroup analysis. The majority of included studies had a small sample size, which contributed to imprecision around the effect estimate.

No evidence was identified to inform the outcomes of infant death up to 4 weeks chronological age and birth before 39 +0 weeks of gestation.

There was no publication bias identified in the evidence. However, the committee noted the influence pharmacological developers may have in these trials as funders, and took this into account in their decision making.

Benefits and harms

The committee discussed that in the case of breech presentation, a discussion with the woman about the different options and their potential benefits, harms and implications is needed to ensure an informed decision. The committee discussed that some women may prefer a breech vaginal birth or choose an elective caesarean birth, and that her preferences should be supported, in line with shared decision making.

The committee discussed that external cephalic version is standard practice for managing breech presentation in uncomplicated singleton pregnancies at or after 36+0 weeks. The committee discussed that there could be variation in the success rates of ECV based on the experience of the healthcare professional providing the ECV. There was some evidence supporting the use of ECV for managing a breech presentation in late pregnancy. The evidence showed ECV had a clinically important benefit in terms of cephalic presentations in labour and cephalic vaginal deliveries, when compared to no intervention. The committee noted that the evidence suggested that ECV was not harmful to the baby, although the effect estimate was imprecise relating to the relative rarity of the fetal death as an outcome.

Cephalic (head-down) vaginal birth is preferred by many women and the evidence suggests that external cephalic version is an effective way to achieve this. The evidence suggested ECV increased the chance for a cephalic vaginal birth and the committee agreed that it was important to explain this to the woman during her consultation.

The committee discussed the optimum timing for ECV. Timing of ECV must take into account the likelihood of the baby turning naturally before a woman commences labour and the possibility of the baby turning back to a breech presentation after ECV if it is done too early. The committee noted that in their experience, current practice was to perform ECV at 37 gestational weeks. The majority of the evidence demonstrating a benefit of ECV in this review involved ECV performed around 37 gestational weeks, although the review did not look for studies directly comparing different timings of ECV and their relative success rates.

The evidence in this review excluded women with previous complicated pregnancies, such as those with previous caesarean section or uterine surgery. The committee discussed that a previous caesarean section indicates a complicated pregnancy and that this population of women are not the focus of this guideline, which concentrates on women with uncomplicated pregnancies.

The committee’s recommendations align with other NICE guidance and cross references to the NICE guideline on caesarean birth and the section on breech presenting in labour in the NICE guideline on intrapartum care for women with existing medical conditions or obstetric complications and their babies were made.

ECV combined with pharmacological agents

There were some small studies comparing a variety of pharmacological agents (including β2 agonists, Ca 2+ channel blockers, µ-receptor agonists and nitric oxide donors) given alongside ECV. Overall the evidence typically showed no clinically important benefit of adding any pharmacological agent to ECV except in comparisons with a control arm with no ECV where it was not possible to isolate the effect of the ECV versus the pharmacological agent. The evidence tended toward benefit most for β2 agonists and µ-receptor agonists however there was no consistent or high quality evidence of benefit even for these agents. The committee agreed that although these pharmacological agents are used in practice, there was insufficient evidence to make a recommendation supporting or refuting their use or on which pharmacological agent should be used.

The committee discussed that the evidence suggesting µ-receptor agonist, remifentanil, had a clinically important benefit in terms reducing breech vaginal births after unsuccessful ECV was biologically implausible. The committee noted that this pharmacological agent has strong sedative effects, depending on the dosage, and therefore studies comparing it to a placebo had possible design flaws as it would be obvious to all parties whether placebo or active drug had been received. The committee discussed that the risks associated with using remifentanil such as respiratory depression, likely outweigh any potential added benefit it may have on managing breech presentation.

There was some evidence comparing different anaesthetics together with ECV. Although there was little consistent evidence of benefit overall, one small study of low quality showed a combination of 2% lidocaine and epinephrine via epidural catheter (anaesthesia) with ECV showed a clinically important benefit in terms of cephalic presentations in labour and the method of birth. The committee discussed the evidence and agreed the use of anaesthesia via epidural catheter during ECV was uncommon practice in the UK and could be expensive, overall they agreed the strength of the evidence available was insufficient to support a change in practice.

Postural management

There was limited evidence on postural management as an intervention for managing breech presentation in late pregnancy, which showed no difference in effectiveness. Postural management was defined as ‘knee-chest position for 15 minutes, 3 times a day’. The committee agreed that in their experience women valued trying interventions at home first which might make postural management an attractive option for some women, however, there was no evidence that postural management was beneficial. The committee also noted that in their experience postural management can cause notable discomfort so it is not an intervention without disadvantages.

Cost effectiveness and resource use

A systematic review of the economic literature was conducted but no relevant studies were identified which were applicable to this review question.

The committee’s recommendations to offer external cephalic version reinforces current practice. The committee noted that, compared to no intervention, external cephalic version results in clinically important benefits and that there would also be overall downstream cost savings from lower adverse events. It was therefore the committee’s view that offering external cephalic version is cost effective and would not entail any resource impact.

Pregnancy week by week
Fetal presentation before birth

The way a baby is positioned in the uterus just before birth can have a big effect on labor and delivery. This positioning is called fetal presentation.

Babies twist, stretch and tumble quite a bit during pregnancy. Before labor starts, however, they usually come to rest in a way that allows them to be delivered through the birth canal headfirst. This position is called cephalic presentation. But there are other ways a baby may settle just before labor begins.

Following are some of the possible ways a baby may be positioned at the end of pregnancy.

Head down, face down

When a baby is head down, face down, the medical term for it is the cephalic occiput anterior position. This the most common position for a baby to be born in. With the face down and turned slightly to the side, the smallest part of the baby's head leads the way through the birth canal. It is the easiest way for a baby to be born.

Head down, face up

When a baby is head down, face up, the medical term for it is the cephalic occiput posterior position. In this position, it might be harder for a baby's head to go under the pubic bone during delivery. That can make labor take longer.

Most babies who begin labor in this position eventually turn to be face down. If that doesn't happen, and the second stage of labor is taking a long time, a member of the health care team may reach through the vagina to help the baby turn. This is called manual rotation.

In some cases, a baby can be born in the head-down, face-up position. Use of forceps or a vacuum device to help with delivery is more common when a baby is in this position than in the head-down, face-down position. In some cases, a C-section delivery may be needed.

Illustration of the head-down, face-up position

Frank breech

When a baby's feet or buttocks are in place to come out first during birth, it's called a breech presentation. This happens in about 3% to 4% of babies close to the time of birth. The baby shown below is in a frank breech presentation. That's when the knees aren't bent, and the feet are close to the baby's head. This is the most common type of breech presentation.

If you are more than 36 weeks into your pregnancy and your baby is in a frank breech presentation, your health care professional may try to move the baby into a head-down position. This is done using a procedure called external cephalic version. It involves one or two members of the health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

If the procedure isn't successful, or if the baby moves back into a breech position, talk with a member of your health care team about the choices you have for delivery. Most babies in a frank breech position are born by planned C-section.

Illustration of the frank breech position

Complete and incomplete breech

A complete breech presentation, as shown below, is when the baby has both knees bent and both legs pulled close to the body. In an incomplete breech, one or both of the legs are not pulled close to the body, and one or both of the feet or knees are below the baby's buttocks. If a baby is in either of these positions, you might feel kicking in the lower part of your belly.

If you are more than 36 weeks into your pregnancy and your baby is in a complete or incomplete breech presentation, your health care professional may try to move the baby into a head-down position. This is done using a procedure called external cephalic version. It involves one or two members of the health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

If the procedure isn't successful, or if the baby moves back into a breech position, talk with a member of your health care team about the choices you have for delivery. Many babies in a complete or incomplete breech position are born by planned C-section.

Illustration of a complete breech presentation

When a baby is sideways — lying horizontal across the uterus, rather than vertical — it's called a transverse lie. In this position, the baby's back might be:

Down, with the back facing the birth canal.
Sideways, with one shoulder pointing toward the birth canal.
Up, with the hands and feet facing the birth canal.

Although many babies are sideways early in pregnancy, few stay this way when labor begins.

If your baby is in a transverse lie during week 37 of your pregnancy, your health care professional may try to move the baby into a head-down position. This is done using a procedure called external cephalic version. External cephalic version involves one or two members of your health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

If the procedure isn't successful, or if the baby moves back into a transverse lie, talk with a member of your health care team about the choices you have for delivery. Many babies who are in a transverse lie are born by C-section.

If you're pregnant with twins and only the twin that's lower in the uterus is head down, as shown below, your health care provider may first deliver that baby vaginally.

Then, in some cases, your health care team may suggest delivering the second twin in the breech position. Or they may try to move the second twin into a head-down position. This is done using a procedure called external cephalic version. External cephalic version involves one or two members of the health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

Your health care team may suggest delivery by C-section for the second twin if:

An attempt to deliver the baby in the breech position is not successful.
You do not want to try to have the baby delivered vaginally in the breech position.
An attempt to move the baby into a head-down position is not successful.
You do not want to try to move the baby to a head-down position.

In some cases, your health care team may advise that you have both twins delivered by C-section. That might happen if the lower twin is not head down, the second twin has low or high birth weight as compared to the first twin, or if preterm labor starts.

Management of Breech Presentation (Green-top Guideline No. 20b)

Summary: The aim of this guideline is to aid decision making regarding the route of delivery and choice of various techniques used during delivery. It does not include antenatal or postnatal care. Information regarding external cephalic version is the topic of the separate Royal College of Obstetricians and Gynaecologists Green-top Guideline No. 20a, External Cephalic Version and Reducing the Incidence of Term Breech Presentation .

Breech presentation occurs in 3–4% of term deliveries and is more common in preterm deliveries and nulliparous women. Breech presentation is associated with uterine and congenital abnormalities, and has a significant recurrence risk. Term babies presenting by the breech have worse outcomes than cephalic presenting babies, irrespective of the mode of delivery.

A large reduction in the incidence of planned vaginal breech birth followed publication of the Term Breech Trial. Nevertheless, due to various circumstances vaginal breech births will continue. Lack of experience has led to a loss of skills essential for these deliveries. Conversely, caesarean section can has serious long-term consequences.

COVID disclaimer: This guideline was developed as part of the regular updates to programme of Green-top Guidelines, as outlined in our document Developing a Green-top Guideline: Guidance for developers , and prior to the emergence of COVID-19.

Version history: This is the fourth edition of this guideline.

There are three types of breech presentation: complete, incomplete, and frank.

Complete breech is when both of the baby's knees are bent and his feet and bottom are closest to the birth canal.

Incomplete breech is when one of the baby's knees is bent and his foot and bottom are closest to the birth canal.

Frank breech is when the baby's legs are folded flat up against his head and his bottom is closest to the birth canal.

There is also footling breech where one or both feet are presenting.

Breech presentation: diagnosis and management

Key messages.

All women with a breech presentation should be offered an external cephalic version (ECV) from 37 weeks, if there are no contraindications.
Elective caesarean section (ELCS) for a singleton breech at term has been shown to reduce perinatal and neonatal mortality rates.
Planning for vaginal breech birth requires careful assessment of suitability criteria, contraindications and the ability of the service to provide experienced personnel.

In June 2023, we commenced a project to review and update the Maternity and Neonatal eHandbook guidelines, with a view to targeting completion in 2024. Please be aware that pending this review, some of the current guidelines may be out of date. In the meantime, we recommend that you also refer to more contemporaneous evidence.

Breech and external cephalic version

Breech presentation is when the fetus is lying longitudinally and its buttocks, foot or feet are presenting instead of its head.

Figure 1. Breech presentations

Breech presentation occurs in three to four per cent of term deliveries and is more common in nulliparous women.
External cephalic version (ECV) from 37 weeks has been shown to decrease the incidence of breech presentation at term and the subsequent elective caesarean section (ELCS) rate.
Vaginal breech birth increases the risk of low Apgar scores and more serious short-term complications, but evidence has not shown an increase in long-term morbidity.
Emergency caesarean section (EMCS) is needed in approximately 40 per cent of women planning a vaginal breech birth.
0.5/1000 with ELCS for breech >39 weeks gestation
2.0/1000 planned vaginal breech birth >39/40
1.0/1000 with planned cephalic birth.
A reduction in planned vaginal breech birth followed publication of the Term Breech Trial (TBT) in 2001.
Acquisition of skills necessary to manage breech presentation (for example, ECV) is important to optimise outcomes.

Clinical suspicion of breech presentation

Abdominal palpation: if the presenting part is irregular and not ballotable or if the fetal head is ballotable at the fundus
Pelvic examination: head not felt in the pelvis
Cord prolapse
Very thick meconium after rupture of membranes
Fetal heart heard higher in the abdomen

In cases of extended breech, the breech may not be ballotable and the fetal heart may be heard in the same location as expected for a cephalic presentation.

If breech presentation is suspected, an ultrasound examination will confirm diagnosis.

Cord prolapse is an obstetric emergency. Urgent delivery is indicated after confirming gestation and fetal viability.

Diagnosis: preterm ≤36+6 weeks

Breech presentation is a normal finding in preterm pregnancy.
If diagnosed at the 35-36 week antenatal visit, refer the woman for ultrasound scan to enable assessment prior to ECV.
Mode of birth in a breech preterm delivery depends on the clinical circumstances.

Diagnosis: ≥37+0 weeks

determine type of breech presentation
determine extension/flexion of fetal head
locate position of placenta and exclude placenta praevia
exclude fetal congenital abnormality
calculate amniotic fluid index
estimate fetal weight.

Practice points

Offer ECV if there are no contraindications.
If ECV is declined or unsuccessful, provide counselling on risks and benefits of a planned vaginal birth versus an ELCS.
Inform the woman that there are fewer maternal complications with a successful vaginal birth, however the risk to the woman increases significantly if there is a need for an EMCS.
Inform the woman that caesarean section increases the risk of complication in future pregnancies, including the risk of a repeat caesarean section and the risk of invasive placentation.
If the woman chooses an ELCS, document consent and organise booking for 39 weeks gestation.

Information and decision making

Women with a breech presentation should have the opportunity to make informed decisions about their care and treatment, in partnership with the clinicians providing care.

Planning for birth requires careful assessment for risk of poor outcomes relating to planned vaginal breech birth. If any risk factors are identified, inform the woman that an ELCS is recommended due to increased perinatal risk.

Good communication between clinicians and women is essential. Treatment, care and information provided should:

take into account women's individual needs and preferences
be supported by evidence-based, written information tailored to the needs of the individual woman
be culturally appropriate
be accessible to women, their partners, support people and families
take into account any specific needs, such as physical or cognitive disabilities or limitations to their ability to understand spoken or written English.

Documentation

The following should be documented in the woman's hospital medical record and (where applicable) in her hand-held medical record:

discussion of risks and benefits of vaginal breech birth and ELCS
discussion of the woman's questions about planned vaginal breech birth and ELCS
discussion of ECV, if applicable
consultation, referral and escalation

External cephalic version (ECV)

ECV can be offered from 37 weeks gestation
The woman must provide written consent prior to the procedure
The success rate of ECV is 40-60 per cent
Approximately one in 200 ECV attempts will lead to EMCS
ECV should only be performed by a suitably trained, experienced clinician
continuous electronic fetal monitoring (EFM)
capability to perform an EMCS.

Contraindications

Table 1. Contraindications to ECV

Precautions

Hypertension
Oligohydramnios
Nuchal cord

Escalate care to a consultant obstetrician if considering ECV in these circumstances.

Perform a CTG prior to the procedure - continue until RANZCOG criteria for a normal antenatal CTG are met.
250 microg s/c, 30 minutes prior to the procedure.
Administer Anti-D immunoglobulin if the woman is rhesus negative.
Do not make more than four attempts at ECV, for a suggested maximum time of ten minutes in total.
Undertake CTG monitoring post-procedure until RANZCOG criteria for a normal antenatal CTG are met.

Emergency management

Urgent delivery is indicated in the event of the following complications:

abnormal CTG
vaginal bleeding
unexplained pain.

Initiate emergency response as per local guidelines.

Alternatives to ECV

There is a lack of evidence to support the use of moxibustion, acupuncture or postural techniques to achieve a vertex presentation after 35 weeks gestation.

Criteria for a planned vaginal breech birth

Documented evidence of counselling regarding mode of birth
Documentation of informed consent, including written consent from the woman
Estimated fetal weight of 2500-4000g
Flexed fetal head
Emergency theatre facilities available on site
Availability of suitably skilled healthcare professional
Frank or complete breech presentation
No previous caesarean section.
Cord presentation
Fetal growth restriction or macrosomia
Any presentation other than a frank or complete breech
Extension of the fetal head
Fetal anomaly incompatible with vaginal delivery
Clinically inadequate maternal pelvis
Previous caesarean section
Inability of the service to provide experienced personnel.

If an ELCS is booked

Confirm presentation by ultrasound scan when a woman presents for ELCS.
If fetal presentation is cephalic on admission for ELCS, plan ongoing management with the woman.

Intrapartum management

Fetal monitoring.

Advise the woman that continuous EFM may lead to improved neonatal outcomes.
Where continuous EFM is declined, perform intermittent EFM or intermittent auscultation, with conversion to EFM if an abnormality is detected.
A fetal scalp electrode can be applied to the breech.

Position of the woman

The optimal maternal position for birth is upright.
Lithotomy may be appropriate, depending on the accoucheur's training and experience.

Pain relief

Epidural analgesia may increase the risk of intervention with a vaginal breech birth.
Epidural analgesia may impact on the woman's ability to push spontaneously in the second stage of labour.

Induction of labour (IOL)

See the IOL eHandbook page for more detail.

IOL may be offered if clinical circumstances are favourable and the woman wishes to have a vaginal birth.
Augmentation (in the absence of an epidural) should be avoided as adequate progress in the absence of augmentation may be the best indicator of feto-pelvic proportions.

The capacity to offer IOL will depend on clinician experience and availability and service capability.

First stage

Manage with the same principles as a cephalic presentation.
Labour should be expected to progress as for a cephalic presentation.
If progress in the first stage is slow, consider a caesarean section.
If an epidural is in situ and contractions are less than 4:10, consult with a senior obstetrician.
Avoid routine amniotomy to avoid the risk of cord prolapse or cord compression.

Second stage

Allow passive descent of the breech to the perineum prior to active pushing.
If breech is not visible within one hour of passive descent, a caesarean section is normally recommended.
Active second stage should be ½ hour for a multigravida and one hour for a primipara.
All midwives and obstetricians should be familiar with the techniques and manoeuvres required to assist a vaginal breech birth.
Ensure a consultant obstetrician is present for birth.
Ensure a senior paediatric clinician is present for birth.

VIDEO: Maternity Training International - Vaginal Breech Birth

Encouragement of maternal pushing (if at all) should not begin until the presenting part is visible.
A hands-off approach is recommended.
Significant cord compression is common once buttocks have passed the perineum.
Timely intervention is recommended if there is slow progress once the umbilicus has delivered.
Allow spontaneous birth of the trunk and limbs by maternal effort as breech extraction can cause extension of the arms and head.
Grasp the fetus around the bony pelvic girdle, not soft tissue, to avoid trauma.
Assist birth if there is a delay of more than five minutes from delivery of the buttocks to the head, or of more than three minutes from the umbilicus to the head.
Signs that delivery should be expedited also include lack of tone or colour or sign of poor fetal condition.
Ensure fetal back remains in the anterior position.
Routine episiotomy not recommended.
Lovset's manoeuvre for extended arms.
Reverse Lovset's manoeuvre may be used to reduce nuchal arms.
Supra-pubic pressure may aide flexion of the fetal head.
Maricueau-Smellie-Veit manoeuvre or forceps may be used to deliver the after coming head.

Undiagnosed breech in labour

This occurs in approximately 25 per cent of breech presentations.
Management depends on the stage of labour when presenting.
Assessment is required around increased complications, informed consent and suitability of skilled expertise.
Do not routinely offer caesarean section to women in active second stage.
If there is no senior obstetrician skilled in breech delivery, an EMCS is the preferred option.
If time permits, a detailed ultrasound scan to estimate position of fetal neck and legs and estimated fetal weight should be made and the woman counselled.

Entrapment of the fetal head

This is an extreme emergency

This complication is often due to poor selection for vaginal breech birth.

A vaginal examination (VE) should be performed to ensure that the cervix is fully dilated.
If a lip of cervix is still evident try to push the cervix over the fetal head.
If the fetal head has entered the pelvis, perform the Mauriceau-Smellie-Veit manoeuvre combined with suprapubic pressure from a second attendant in a direction that maintains flexion and descent of the fetal head.
Rotate fetal body to a lateral position and apply suprapubic pressure to flex the fetal head; if unsuccessful consider alternative manoeuvres.
Reassess cervical dilatation; if not fully dilated consider Duhrssen incision at 2, 10 and 6 o'clock.
A caesarean section may be performed if the baby is still alive.

Neonatal management

Paediatric review.
Routine observations as per your local guidelines, recorded on a track and trigger chart.
Observe for signs of jaundice.
Observe for signs of tissue or nerve damage.
Hip ultrasound scan to be performed at 6-12 weeks post birth to monitor for developmental dysplasia of the hip (DDH). See Neonatal eHandbook - Developmental dysplasia of the hip .
