Summary
A patient with a traumatic ulnar nerve interruption at the level of the elbow is presented; the motor function of the hand remained intact. Electromyographic studies demonstrated a functional median-to-ulnar motor nerve anastomosis in the forearm. The literature on this aberration of innervation is reviewed, and problems of diagnosis and the treatment are discussed.
