Why is it important?
Introduction: In humans, a hook-like bony process called Supracondylar process is occasionally seen on the anteromedial surface of the humerus. It has also been referred as the supraepitrochlear, supracondyloid, epicondyloid, or supratrochlear spur. It is curved, directed downwards and forwards, and its pointed apex is sometimes connected to the medial border just above the medial epicondyle by fibrous band known as Struthers ligament. Supracondylar process represents the embryologic vestigial remnant of climbing animals and seen in many reptiles, most marsupials, cats, lemurs and American monkeys. Aim: To study the incidence of supracondylar process of humerus. Materials and Methods: 88 adult dry humeri were collected from the Department of Anatomy, Subbaiah Institute of Medical Sciences and were examined for any osseous projection from the distal part. Results: Out of 88 humeri, we found one humerus of left side with a bony projection from anteromedial surface of its distal shaft. The bone was then examined, studied, photographed and its dimensions were recorded using Vernier calipers. Conclusion: Knowledge of this variation is of great importance to anatomists and anthropologists because of the possible link to the origin and relation of human races and also to radiologists, orthopaedicians and surgeons due to its clinical implications.
