Painful Instability occurs when a shoulder is forced beyond the joint's normal range of motion causing the ball to move abnormally in the socket. Arthritis may be caused by long-term wear and tear, infections, injuries or a variety of other diseases. It is characterized by roughened joint surfaces with worn cartilage. Fragmentation of bone and cartilage is also known as loose bodies. The surgeon may often be able to correct the problem using this procedure by removing loose unwanted tissue from the joint, with less disturbance to the joint.
Recovery time is usually short.
It is often performed for athletes involved in throwing sports who suffer from recurrent dislocations and subluxations. It allows the patient to return to contact sports such as baseball, football, wrestling, and ice hockey because the muscles and tendons are returned to their anatomic locations. The surgery is commonly performed on older patients who complain of pain and weakness in the deltoid region that occurs with normal daily activities as well as work and sport. The pain is often worse at night. This surgery is sometimes performed for patients with arthritis in the shoulder joint because it provides pain relief, which is the major indication for the procedure.
