What is the McRoberts maneuver?

The McRoberts maneuver involves flexing the mother's legs tightly to her abdomen. This technique is utilized during episodes of shoulder dystocia, a situation where the shoulder of the baby becomes lodged behind the mother's pelvic bone during delivery. By flexing the legs, the pelvis is effectively widened, which can help create additional space for the baby’s shoulder to clear the pubic symphysis and facilitate delivery.

This maneuver can significantly alter the angle of the pelvis and reduce the potential impacts of the dystocia, making it a crucial intervention in emergency obstetric scenarios. The effectiveness of this maneuver is also supported by the physiological changes in pelvic alignment it promotes, which can provide more room for the baby’s shoulders to navigate through the birth canal.
