Abstract
Introduction: Supracondylar spur is a bony projection about 2-20 mm in length, occasionally projects from the anteromedial surface of the shaft of humerus about 5 cm proximal to the medial epicondyle. It represents an embryonic vestigial remnant in climbing animals and felines. It may be joined to the medial epicondyle by a fibrous band called ligament of struthers, which may ossify. It is usually asymptomatic but can present with the symptoms like median nerve and brachial artery compression when associated with struthers ligament. Materials and Methods: 127 dried humeri were studied from the department of anatomy, RIMS, Ranchi. Bones were examined for supracondylar spur, its dimensions were recorded with vernier caliper and photographs taken. Result: Out of 127 dried humeri only one humerus with supracondylar spur of length 2.4 cm was found on the anteromedial surface of left humerus at a distance of 5.6 cm from the tip of medial epicondyle. The incidence calculated in our study was 0.78%. Conclusion: Its incidence reported in past varies from 0.1% to 2.7% in different races. Our study revealed its low incidence in Jharkhand population.
