Hints & Solutions
(b) Glenoid cavity is found in pectoral girdle. A tear of the rim below the middle of the glenoid socket that also involves the inferior glenohumeral ligament is called a Bankart lesion. Tears of the glenoid rim often occur with other shoulder injuries, such as a dislocated shoulder (full or partial dislocation). Trauma may cause a fracture of the humerus (ball) or the glenoid (socket) of the shoulder joint. The majority of these injuries can be treated without surgery with a good, long-term result. Some fractures are better treated with surgery because they may carry a high risk of arthritis if left alone.
