Intraoperatively proven anomalous Struthers' ligament diagnosed by MRI.
A case of median nerve entrapment at the elbow between the supracondylar process and an anomalous insertion of Struthers' ligament is presented. The diagnosis of anomalous insertion of the ligament was made by MRI and confirmed at operation. Struthers' ligament originated as usual from the supracondylar process but did not reach the medial epicondyle of the humerus, inserting instead in the brachial fascia above the epicondyle. The incomplete Struthers' ligament functioned, however, as a complete ligament. It produced symptoms identical to supracondylar process syndrome. Excision of the supracondylar process of the humerus and Struthers' ligament relieved symptoms in this athlete.
