Cubital tunnel syndrome: anterior transposition with epicondylar osteotomy.

Abstract

In this article we reviewed nine consecutive patients operated on for cubital tunnel syndrome. They underwent a modification of the Learmonth procedure in which a medial epicondyle osteotomy was performed. The dissection was completed within intermuscular tissue planes to allow the ulnar nerve to be transposed submuscularly. The medial epicondyle was then replaced and secured using two 4.0 mm AO cancellous screws. This article describes an operative technique, which has not been definitively described previously. Eight of nine patients demonstrated both subjected and objective improvement postoperatively. Eight patients returned to work following surgery. We fell that medial epicondylar osteotomy and screw fixation has minimized operative bleeding, subsequent inflammation, and fibrosis. Immediate range of motion activities have been encouraged, and earlier complete rehabilitation demonstrated.
