Surgical management of leprous ulnar neuritis.

An analysis of the results of neurolysis with careful anterior transposition of the ulnar nerve in 17 cases of severe leprous neuritis is described. Pain and paresthesia were relieved in all patients within 48 to 72 hours after the operation. Recoverable cases showed some evidence of sensory and motor recovery within three weeks to three months, and six months of the operation, respectively. The amount of recovery was directly related to the extent and stage of involvement of the nerve. Results of prophylactic anterior transposition on the ulnar nerve in two patients with recurrent dislocation were encouraging.
