Median to radial nerve transfer to restore wrist and finger extension: technical nuances.

Abstract

Traditional methods for restoring finger and wrist extension following radial nerve palsy include interposition nerve grafting or tendon transfers. We have described the utilization of distal nerve transfers for the restoration of radial nerve function in the forearm. We review the neuroanatomy of the forearm and outline the steps required for the implementation of this transfer. We use a step-by-step procedural outline and detailed photographs, line drawings, and video to describe the procedure. This approach is technically feasible and is a reconstructive option for patients with this nerve deficit.
