Results of anterior transposition of the ulnar nerve for ulnar neuritis.

A clinical and electrophysiological followup study was done on 23 patients with ulnar neuritis treated by surgical transposition of the nerve at the elbow. Pain was relieved in all those affected and other sensory symptoms showed some degree of improvement in most. Weakness tended to persist, but recovery of full use of the hand followed operation in 74%. Muscle wasting was the least likely to improve. The chance of recovery after operation was greatly reduced in patients in whom preoperative symptoms had been present for more than one year.
