Though rare, shoulder dystocia complicates between 0.15 and 1.7% of vaginal deliveries. It is defined in one of two ways: more than 60 s from delivery of the head to the body or the need for additional obstetric maneuvers to deliver the shoulder of the fetus. Maneuvers commonly used include McRoberts, suprapubic pressure, Wood’s screw, and delivery of the posterior arm .
