This exhibit depicts traumatic left brachial plexus neuromas, scarring, and nerve graft repairs. Pre-operatively, neuromas are seen at C5-6 and C7-8. Severe scar tissue surrounds the brachial plexus and entraps the phrenic nerve that controls the diaphragm. Post-operatively, the scar tissue has been removed, and the C5-6 neuroma has been partially excised. C4 sensory nerves were harvested and used to create two nerve grafts. One graft was placed from C6 to the anterior division of the upper trunk, and the other was placed from C5 to the posterior division of the upper trunk.
