Figure 1. Patient 1 with intraoperative findings demonstrating a large proximal neuroma of the median nerve and an 8-cm nerve gap present upon resection of the allograft. The arrows demonstrate the location of the histological sections. Note the abundance of myelinated axons in the median nerve proximal to the coaptation site of the proximal median nerve and the allograft. Note the decrease of myelinated axons across the allograft, as myelinated axons are visible within the midgraft, but only a few myelinated axons present within the distal nerve.
