Treating a Scar-Tethered Median Nerve Neuroma in Continuity With a Fly-Over Nerve Grafting Technique.

Peripheral nerve neuromas may present significant therapeutic challenges especially when neuromas in continuity are scar-tethered to adjacent vital structures. We report a case of a patient who presented with delayed neurotmesis of median and ulnar nerves in the arm while extensive scarring of the median nerve was found in close proximity to the repaired brachial artery. For the surgical restoration of the continuity of the median nerve, the scarred segment was left in situ to avoid reinjury of the brachial artery and a "fly-over" nerve grafting technique with sural nerve autografts was employed.
