Abstract
We report a case of right shoulder contracture with ectopic ossification of the coracoclavicular ligament after distal end fracture of the clavicle. This male patient had struck his right shoulder and fractured the distal end of the right clavicle. The fracture was treated conservatively, and the bone healed six weeks after injury. However, the patient returned four and a half months later with contracture of the right shoulder. As two months of rehabilitation facilitated no improvement, resection of the ossified coracoclavicular ligament and manipulation were performed. The range of motion of the right shoulder returned to almost normal, and this condition was retained at six months after surgery. Although a good short-term result was obtained by resection of the ossified coracoclavicular ligament in this case, further monitoring for re-ossification will be necessary.
