Safety and efficacy of vaginal delivery after successful external cephalic version for singleton breech pregnancy: a retrospective cohort study
This retrospective cohort study demonstrates that external cephalic version is a safe and effective intervention for singleton term breech pregnancies, with successful procedures leading to vaginal delivery outcomes comparable to spontaneous cephalic births and showing particular efficacy in multiparous women.

At the end of a pregnancy, most babies settle into a head-down position, ready to emerge through the birth canal. This is the natural and safest way for a baby to be born. However, in a small number of pregnancies, the baby remains in a breech position, with the buttocks or feet pointing downward instead of the head. For decades, the standard medical response to a breech baby at term has been to schedule a cesarean section, a surgical delivery, to avoid the risks associated with a vaginal breech birth. While this approach protects the baby from certain immediate dangers, it also means more mothers undergo major surgery, which carries its own risks of bleeding, infection, and complications in future pregnancies.
Doctors have long had a tool to try and change this situation before labor begins. Called external cephalic version, the procedure involves a doctor applying gentle, firm pressure on the mother's abdomen to manually turn the baby from a breech position to a head-down position. It is a non-invasive technique, but it has not been used everywhere because of lingering worries. Some medical teams fear the procedure might cause the placenta to separate too early or distress the baby, while others wonder if a baby turned this way will still have a smooth labor later on. The question remains: is this manual turn safe enough to try, and if it works, does the baby born afterward face the same risks as a baby who was head-down from the start?
Researchers at the Zhangzhou Affiliated Hospital of Fujian Medical University set out to answer these questions by looking back at their own recent experiences. They studied a group of women who had this procedure performed between June 2024 and April 2026. The team focused on 50 women whose babies were successfully turned to a head-down position and who went on to have a vaginal delivery. To see how these outcomes compared to the norm, they matched them with another group of 50 women who had always been in a head-down position and delivered vaginally without any intervention. The researchers carefully tracked everything from the length of labor to the health of the newborns, looking for any signs that the manual turning had caused harm or made the birth more difficult.
The results of their review were reassuring. The procedure worked in more than seven out of ten attempts, turning the breech babies to a head-down position. Among the women whose babies were successfully turned, nearly nine out of ten went on to have a vaginal delivery. The researchers found no significant difference between the two groups in how long labor lasted, how much blood the mothers lost, or the health of the babies after birth. Every baby in both groups had a strong heart rate and a healthy score immediately after being born, and none required special care in the neonatal intensive care unit due to the turning procedure. The only serious complications, such as a rare separation of the placenta, occurred in the small group of women for whom the procedure did not work, not in those who successfully turned their babies and delivered vaginally.
The study also highlighted that the procedure seemed particularly effective for women who had given birth before. In this group, every single woman whose baby was turned successfully went on to have a vaginal delivery. For first-time mothers, the success rate was slightly lower, but still substantial, with about two-thirds achieving a vaginal birth. The researchers noted that in the few cases where a baby turned back to a breech position after the procedure, a second attempt was successful, and those women also had safe vaginal deliveries. This suggests that even if a baby moves back, it does not necessarily mean a surgical delivery is the only option.
These findings suggest that when performed by experienced doctors in a hospital setting prepared for emergencies, turning a breech baby manually is a safe and effective way to increase the chances of a vaginal birth. The study indicates that a baby turned this way does not face higher risks than a baby who was naturally head-down. The authors conclude that with careful selection of patients and proper monitoring, this technique can help more mothers avoid unnecessary surgery. They emphasize that the procedure holds special value for women who have had previous births, where the likelihood of a successful vaginal delivery is extremely high. The work supports the idea that this established method should be offered more widely, provided that medical teams are trained to perform it skillfully and that mothers are well-informed about the process.
