Reset Neurectomy for Cutaneous Nerve Injuries

Diffuse cutaneous nerve injuries, often caused by a crush mechanism, are challenging for the nerve surgeon. Discrete nerve transections and focal neuromas are easier to identify and have a more distinct treatment algorithm. Following crush injury to a noncritical sensory nerve, a successful local anesthetic block proximal to the injury may help determine the possibility of surgical intervention. In these cases, we describe a technique of "reset neurectomy" whereby a neurectomy is performed proximal to the zone of injury, and immediate repair or reconstruction (with or without a nerve graft) is performed. This technique may be useful in cases of diffuse, nontransection nerve injuries in which neuropathic pain is the primary symptom.
