The McRoberts maneuver is an obstetrical maneuver to manage shoulder dystocia.  The OB will take the mother's leg and flex them back towards her stomach and then abduct it away from her stomach.   The hope is to shrink the angle between the spinal column and the sacrum to make it easier for the child's shoulder to clear the birth canal.   Most doctors report that the McRoberts maneuver typically solves a shoulder dystocia complication.  Other methods are suprapubic pressure, the Woods screw maneuver, and delivery of the posterior arm.
