Background: Supracondylar process or spur is a hook shaped projection from the anteromedial surface of the lower part of humerus. Its pointed apex is connected to medial epicondyle by a fibrous band known as Struther’s ligament (in approximately 1% individuals) which completes a foramen through which median nerve and brachial artery is transmitted.Materials and method: 200 dried humeri were studied in the Department of Anatomy, Ballari Medical College and Research Centre, Ballari. Bones were examined for supracondylar process. The measurements were recorded and photographs were taken.Results: Out of 200 dried humeri examined three humeri were found to have supracondylar process. The incidence calculated was 1.5%.Conclusions: The supracondylar process is often mistaken for pathological conditions like osteochondroma or myositis ossificans. Even though it is usually clinically silent, sometimes it becomes symptomatic due to compression of median nerve and claudication of brachial artery. There may be pain in medial epicondyle, tingling sensation over area supplied by median nerve. Ulnar artery is rarely involved in case of high division of brachial artery. |
