In the dynamic field of obstetrics, a myriad of positions and complications can make the birthing process a complex journey.
Picture this: a persistent occipitotransverse position, an intriguing term that describes a baby’s head facing the wrong way in the birth canal.
How can modern obstetrics navigate such challenges?
Join us as we delve into the world of innovative techniques such as internal rotation, vacuum extraction, forceps, and even caesarean section to overcome these obstacles and ensure the safe delivery of precious bundles of joy.
persistent occipitotransverse position
Persistent occipitotransverse position refers to a malpresentation where the baby’s head is positioned sideways in the mother’s pelvis, with the occiput (back of the head) facing one of the mother’s hips.
This position can lead to complications during labor and delivery, such as prolonged labor, obstructed labor, and increased risk of trauma to the genital tract.
Factors that can contribute to this position include defects in the powers (such as uterine inertia), defects in the passages (such as contracted pelvis), and defects in the passenger (such as preterm fetus or multiple pregnancies).
The diagnosis of occipitotransverse position can be made through ultrasonography and lateral view x-ray.
Normal mechanism of labor involves the baby’s head engaging in the pelvis in an occipito-anterior position and rotating to occipito-posterior position during delivery.
However, in occipitotransverse position, the baby’s head fails to rotate and can become stuck.
Factors favoring long anterior rotation, such as a well-flexed head, good uterine contractions, roomy pelvis, and good pelvic floor, can help in resolving this position.
However, if there is failure of long anterior rotation due to factors like uterine inertia, contracted pelvis, or lax/rigid pelvic floor, management methods may be required.
Various methods can be employed to manage a persistent occipitotransverse position.
These include internal rotation, direct occipito-posterior management, deep transverse arrest management, vacuum extraction, manual rotation, forceps (such as Kielland’s or Barton’s forceps), Scanzoni double application, caesarean section, and craniotomy.
The choice of method will depend on the specific circumstances and preferences of both the healthcare provider and the mother.
In modern obstetrics, preferred methods usually aim to maximize safety and minimize complications, such as vacuum extraction or caesarean section.
Close monitoring of the progress of labor and fetal wellbeing is crucial throughout the management process.

Pro Tips:
1. The occipitotransverse position, also known as the persistent posterior position, occurs when the baby’s head is facing forward, putting pressure on the mother’s sacrum during childbirth.
2. This position is relatively rare, occurring in only about 6% of pregnancies.
3. Occipitotransverse position may result in a longer and more difficult labor due to the baby’s position and the increased pressure on the mother’s lower back.
4. Babies in this position often require more manual intervention or assistance during delivery, such as forceps or vacuum extraction.
5. To help encourage babies in the occipitotransverse position to rotate to the desired anterior position, certain exercises, positions, and techniques, such as pelvic tilts or spinning babies exercises, can be helpful.
Persistent Occipitotransverse Position
Persistent occipitotransverse position, also known as posterior occiput transverse (POT) position, is a malpresentation that occurs in obstetrics. In this condition, the fetal occiput (back of the head) is positioned towards the mother’s side, either left or right, instead of towards the front or back.
This abnormal positioning can make the process of labor more difficult and increase the risk of complications for both the mother and the baby. In a persistent occipitotransverse position, the baby’s head is not engaged in the birth canal, leading to delays in descent and prolonged labor.
- Implications of persistent occipitotransverse position:
- Difficulties during labor
- Increased risk of complications for both mother and baby
It is important to note that this condition poses challenges and may require additional medical intervention to ensure a safe delivery.
Malpresentations And Malpositions In Obstetrics
Malpresentations and malpositions are abnormal fetal positions during labor and delivery. The most common presentation is vertex, where the baby’s head is down and facing the mother’s back. However, there are other malpresentations that can occur:
- Occipitoposterior (OP) presentation: In this position, the baby’s head is facing the mother’s abdomen instead of her back.
- Breech presentation: The baby’s buttocks or feet are positioned to come out first instead of the head.
- Shoulder presentation: The baby is sideways, with one or both shoulders positioned to come out first.
- Face presentation: The baby’s face is positioned to come out first instead of the head.
Malpositions, on the other hand, refer to variations in the fetal head position within the birth canal. One example is the persistent occipitotransverse position, where the baby’s head is positioned horizontally instead of vertically.
Managing malpositions is crucial to ensure a safe outcome for both the mother and the baby. Careful attention and appropriate interventions are required to minimize potential complications.
Improvements:
- Added bullet points to list the different malpresentations.
- Clarified the definition of malpositions.
- Emphasized the importance of careful management for a safe outcome.
- Removed the mention of a blockquote, as it was not specified where it should be used.
Vertex Presentation
Vertex presentation is the ideal fetal position for a vaginal birth. In this presentation, the baby’s head is fully flexed, resting on the mother’s pubic bone, with the occiput facing towards her back. This position allows for the smooth progression of labor and descent through the birth canal. However, when the occiput is directed towards the mother’s side, as in the case of persistent occipitotransverse position, it can create challenges during labor.
Key points:
- Vertex presentation is the ideal position for a vaginal birth
- Baby’s head is fully flexed and rests on the mother’s pubic bone
- Occiput faces towards the mother’s back
- Smooth progression of labor and descent through the birth canal
- Challenges may arise when the occiput is directed towards the mother’s side
Note: Persistent occipitotransverse position can create challenges during labor.
Left Occipito-Anterior Position
The left occipito-anterior (LOA) position is widely regarded as the optimal position for delivery. In LOA, the baby’s head is flexed and facing towards the mother’s back, with the occiput positioned towards her left side. This position enables the baby to fit most effectively through the pelvis, thereby reducing the chances of prolonged labor and associated complications. However, when a persistent occipitotransverse position occurs, the baby’s head is turned towards the mother’s left side, posing additional challenges during labor.
- LOA position: baby’s head flexed and facing the mother’s back, occiput towards the left side.
- Optimal fit through the pelvis.
- Reduces the risk of prolonged labor and complications.
- Occipitotransverse position: baby’s head turned towards the mother’s left side.
- Labor becomes more challenging.
Persistence of occipitotransverse position can pose difficulties during delivery.
Right Occipito-Anterior Position
Similar to the LOA position, the right occipito-anterior (ROA) position is also considered favorable for vaginal delivery. In ROA, the baby’s head is flexed and facing towards the mother’s back, with the occiput positioned towards her right side. This position facilitates the rotation and descent of the head through the birth canal. Persistent occipitotransverse position, in contrast, indicates that the head is turned towards the mother’s right side, posing difficulties for labor progression.
- ROA position is favorable for vaginal delivery
- Baby’s head is flexed and facing the mother’s back
- Occiput positioned towards the mother’s right side
- ROA position facilitates rotation and descent of the head through the birth canal
- Persistent occipitotransverse position poses difficulties for labor progression
“ROA position is considered favorable for vaginal delivery. It facilitates the rotation and descent of the head through the birth canal.”
Defects In The Powers
The powers in obstetrics refer to the forces involved in labor and delivery. Defects in the powers can occur due to various factors, such as inadequate uterine contractions or weak maternal effort. These defects can result in a delay in the progress of labor, leading to complications.
In cases of persistent occipitotransverse position, the powers may need to be augmented through the use of synthetic oxytocin to establish regular and effective contractions and facilitate fetal descent.
Pendulous Abdomen
A pendulous abdomen is a condition where the pregnant uterus is positioned prominently forward and downward, exerting strain on the supporting ligaments. This can have an impact on the labor process, making it more difficult for the baby to engage and descend into the pelvis. In situations where there is a persistent occipitotransverse position, a pendulous abdomen can complicate things even further by hindering the rotational movements of the baby’s head.
Key points:
- Pendulous abdomen refers to an abdominal condition during pregnancy.
- The uterus is positioned prominently forward and downward, causing strain on ligaments.
- It can make it challenging for the baby to engage and descend into the pelvis during labor.
- In cases of persistent occipitotransverse position, the condition can complicate the rotation of the baby’s head.
A pendulous abdomen may pose additional challenges during labor, particularly when the baby’s head is in a persistent occipitotransverse position.
Defects In The Passages
Defects in the passages can contribute to difficulties in labor, especially in cases of malpresentations or malpositions. Contracted pelvis and uterine anomalies can impede the optimal alignment and descent of the baby, hindering the progress of labor.
In the case of persistent occipitotransverse position, the baby’s head may face additional challenges when passing through a narrowed pelvis or an abnormally shaped birth canal, which can further prolong labor.
Contracted Pelvis
A contracted pelvis refers to an abnormal narrowing of the maternal pelvis, which can impede the descent of the baby during labor. This condition can be a result of various factors, including anatomical abnormalities or pelvic growth disturbances.
One specific situation in which a contracted pelvis can pose additional challenges is when the baby is in a persistent occipitotransverse position. In such cases, the narrow pelvis can exacerbate the difficulties faced during labor, potentially requiring interventions like cesarean section or instrumental delivery.
To summarize the key points:
- A contracted pelvis is characterized by an abnormal narrowing of the maternal pelvis.
- It can impede the descent of the baby during labor.
- The condition can be caused by anatomical abnormalities or pelvic growth disturbances.
- When a baby is in a persistent occipitotransverse position, a contracted pelvis can further complicate labor.
- Interventions such as cesarean section or instrumental delivery may be necessary in these cases.
It is important to note that a contracted pelvis can significantly impact the birthing process and may require medical interventions to ensure a safe delivery.
Uterine Anomalies
Uterine anomalies, also known as congenital uterine abnormalities, are structural irregularities in the shape or size of the uterus. These anomalies can affect the position and descent of the baby during labor. In cases of persistent occipitotransverse position, certain uterine abnormalities, such as a bicornuate uterus or a septate uterus, can contribute to the malposition and make labor more complex. Proper diagnosis and monitoring are essential in managing such cases effectively.
Stay tuned for the next part of this comprehensive guide, where we will explore more aspects of persistent occipitotransverse position, including the mechanisms of labor and management strategies.
- Uterine anomalies, or congenital uterine abnormalities, refer to structural irregularities in the shape or size of the uterus.
- These anomalies can impact the position and descent of the baby during labor.
- Certain uterine abnormalities like a bicornuate uterus or a septate uterus can contribute to malposition and complicate labor.

You may need to know these questions about persistent occipitotransverse position
What is the most common cause of persistent Occipito-posterior position?
The most common cause of persistent Occipito-posterior position is a combination of the shape of the pelvis and maternal kyphosis. Anthropoid and android pelvises with narrow fore-pelvis can make it difficult for the baby’s head to rotate into the anterior position. Additionally, maternal kyphosis, which is the convexity of the foetal back fitting with the concavity of the lumbar kyphosis, can contribute to the persistence of occipito-posterior positioning. These factors can make it challenging for the baby’s head to align properly during labor and delivery.
What is persistent Occipito-posterior positions?
Persistent occipito-posterior positions, also known as occiput posterior position, refers to the positioning of the fetal head at the posterior position during the second stage of labor. This positioning occurs irrespective of the delivery method. The occurrence of delivery in the occiput posterior position ranges from 5% to 12%.
What is a persistent fetal position?
A persistent fetal position refers to a situation during labor and delivery where the baby is positioned in an occiput posterior position for an extended period. This position is associated with various complications and interventions. It can cause prolonged stages of labor, necessitating the use of oxytocin augmentation, epidural analgesia, and even assisted vaginal delivery. This position also increases the risk of perineal lacerations, cesarean delivery, excessive blood loss, and postpartum complications such as chorioamnionitis. Overall, managing and correcting persistent fetal positions during labor is crucial to ensure a successful delivery and minimize potential complications.
What does the term persistent Occipito-posterior position indicate about the occiput?
In cases of persistent occipitoposterior position, it suggests that the occiput, which is the back part of the baby’s head, does not rotate forwards as it normally would during labor. Instead, the sinciput, which is the front part of the baby’s head, reaches the pelvic floor first and rotates forwards. As a result, the occiput ends up in the hollow of the sacrum, and the baby is born facing the pubic bone, known as face to pubis. This specific positioning indicates a deviation from the typical rotation of the occiput during the birthing process.
