Left shoulder pain acute, persistent pain and immobility for 4 weeks. Unable to externally rotate or laterally abduct above horizontal. Evaluate for rotator cuff tear. ROTATOR CUFF: There is a partial thickness tear of the distal fibers of the supraspinatus tendon. The supraspinatus muscle appears normal for age. The infraspinatus tendon is intact and the muscle is normal in appearance for age. The teres minor muscle/tendon are intact. There is thickening and increased signal intensity within the subscapularis tendon compatible with tendinosis. Additionally, there is a full thickness insertional tear of the subscapularis without tendon retraction. The subscapularis muscle appears normal for age.SUPRASPINATUS OUTLET: Moderate to severe osteoarthritis affects the acromioclavicular joint. There is a small amount of fluid within the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is thinning of the articular cartilage of the superior glenoid. The labrum is grossly intact.BICEPS TENDON: There is thickening and increased signal intensity within the proximal portion of the long head of the biceps tendon compatible with tendinosis. ADDITIONAL
