McRoberts maneuver

It is named after William A. McRoberts, Jr.[1] It is employed in case of shoulder dystocia during childbirth and involves hyperflexing the mother's legs tightly to her abdomen.

It is effective due to the increased mobility at the sacroiliac joint during pregnancy, allowing rotation of the pelvis and facilitating the release of the fetal shoulder.

Current guidelines strongly recommend against pulling on the infants head, as this could lead to brachial plexus injury.

Instead, support while keeping the neck straight is indicated.

[3] Note that suprapubic pressure and McRobert's maneuver together will resolve 90% of cases.
