title: Direct muscle neurotization recovers gastrocnemius muscle function.
abstract: This case report describes a devastating injury in which a distal motor nerve had been avulsed from the muscle belly and was not available for reconstruction. This otherwise irreparable posterior tibial nerve injury was successfully treated by direct neurotization of the muscle belly. The patient did have one small, intact, muscular branch to the medial gastrocnemius muscle; however, electrodiagnostic and clinical examination and recovery pattern suggested the neurotization procedure was responsible for the functional recovery. In the rare situation where no distal nerve is available, and tendon transfers or arthrodesis are inappropriate, direct muscle neurotization can be considered as a salvage technique.
