Stabilized subcutaneous ulnar nerve transposition with immediate range of motion. Long-term follow-up.

Background: Anterior transposition of the ulnar nerve at the elbow produces generally good results regardless of whether the nerve is transposed subcutaneously, intramuscularly, or submuscularly. The eventual recovery of nerve function is related less to the specific surgical technique than to the severity of the intrinsic nerve pathology. A primary variable in surgical management is the duration of postoperative elbow immobilization.
