The remaining rotator cuff tendons appear normal. There is mild fatty atrophy of the supraspinatus and infraspinatus muscles. The subscapularis and teres minor muscles appear normal. SUPRASPINATUS OUTLET: Moderate osteoarthritic changes affect the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: Mild to moderate osteoarthritic changes affect the glenohumeral joint, which is otherwise in anatomic alignment.
