Cubital tunnel syndrome. Treatment by medial epicondylectomy.

Thirty patients ranging in age from twenty-five to seventy-seven years old underwent medial epicondylectomy with anterior transposition of the ulnar nerve for the cubital tunnel syndrome. Presenting symptoms invariably included hypesthesia in the hand; other common complaints included dysesthesia and weakness of grip. The preoperative nerve-conduction velocity was slowed in all the patients studied. Postoperative responses in all patients included almost immediate relief of pain, no limitation of range of motion of the elbow, and a return to normal of nerve-condition velocity in all but two of the patients tested. The procedure is recommended for patients with cubital tunnel syndrome associated with abnormal nerve-conduction velocity.
