3d custom medical animation of the baby's shoulder becoming impacted on the mother's pubic symphysis during one contraction resulting in a stretching of the baby's brachial plexus nerves. A healthcare professional removes the nuchal cord, places the mother in McRobert's position, applies suprapubic pressure, attempts Wood's corkscrew maneuver, attempts a posterior shoulder and posterior arm delivery and then finally frees the shoulder with suprapubic pressure allowing the baby to be delivered with gentle axial traction.
