Shoulder duplication in constriction band syndrome: a case report

A 2.5 year old girl is presented with both hands constriction bands leading to distal amputations and the rare deformity of shoulder duplication in the right side accompanying constriction skin marking over the affected shoulder. The cephalomedial scapula articulated with the clavicle and the caudolateral scapula articulated with humeral head. The most important physical finding which could explain the pathophysiology of this rare anomaly, was constriction band marking over the right shoulder. Shoulder range of motion was limited but still functional and no surgical intervention was required for the scapular duplication.
