Stabilized subcutaneous transposition of the ulnar nerve.

We treated 50 patients (average age 47.9 years) with a stabilized subcutaneous transposition of the ulnar nerve. The average follow-up period was 42.4 months. The indication was cubital tunnel syndrome in 19 patients and injuries around the elbow in 31 patients. Postoperatively, satisfactory results were obtained in all the patients, and there was no complication or aggravation of the preoperative symptoms. None of the patients experienced slipping back of the nerve to the cubital tunnel. In the 31 patients with injuries around the elbow, there was only one patient with transient aggravation of parasthaesiae in the ulnar nerve region. Stabilized subcutaneous transposition is a simple and less invasive procedure that can facilitate decompression and prevent slipping back of the nerve. This procedure also can be applied to patients with injuries around the elbow that require ulnar nerve transfer.
