Use of the medial intermuscular septum as a fascial sling during anterior transposition of the ulnar nerve.

A new technique using the released medial intramuscular septum as a fascial or fasciodermal sling to prevent posterior subluxation of the ulnar nerve following subcutaneous transposition is described. The technique is simple and prevents subluxation, yet it still allows free excursion of the ulnar nerve and postoperative rehabilitation is begun immediately.
