Surgical treatment of ulnar neuropathy.

Ulnar neuropathy is a well recognized clinical entity caused by a variety of pathological lesions around the elbow. The characteristic features include paresthesia and numbness in the little finger and medial half of the fourth digit, weakness of the small muscles of the hand innervated by the ulnar nerve, and a positive Tinel's sign. The diagnosis is confirmed by electrophysiological studies. Current methods of treatment are anterior transposition, neurolysis and medial epicondylectomy of the humerus. Forty-four patients with ulnar neuropathy are described in the present report. Most were males with a median age of 45. The left side was involved more frequently. Results of subcutaneous anterior transposition and medial epicondylectomy are presented along with a review of the literature.
