Left Brachial Plexus Stretch Injury
This exhibit depicts the condition of an infant brachial plexus after a shoulder dystocia injury. Shoulder dystocia is an obstetric emergency in which the fetal anterior shoulder is trapped behind the mother’s pelvis during vaginal birth. This causes stretching of the C5-6 nerve roots and superior trunk. Pre-operatively, scar tissue has trapped the brachial plexus, and an extraforaminal C5-6 neuroma has developed. This is surgically repaired by removing the scar tissue and partially excising the neuroma. Nerve grafts are then harvested from the leg and used to restore nerve conduction. A graft is placed from C5 to the suprascapular nerve, and from C6 to the superior trunk.
