Chronic posterior dislocation of shoulder

We concluded that chronic PDS could have fractures of tuberosities and/or proximal metaphysis in addition to bone loss in humeral head. The treatment is guided by all three factors-amount of bone loss in humeral head, malunion of GT and proximal humeral metaphysis. The proposed classification can help in choosing the optimum treatment out of joint salvage procedure, anatomic shoulder replacement and reverse shoulder arthroplasty.
