Description: This medical exhibit pictures a mid-line cut-away view of a normal vaginal delivery with a classic depiction of the birthing injury shoulder dystocia, with subsequent stretching and injury of the baby's brachial plexus. The baby's shoulder is partially trapped beneath the mother's pubic symphysis (pubic bone). As the deliverer exerts more pressure to extract the baby, the brachial plexus nerves stretch and are injured.
