Limited range of motion ROTATOR CUFF: There is a complete tear of the supraspinatus tendon with approximately 3 cm of retraction. The tear extends posteriorly to involve the majority of the infraspinatus tendon which is similarly retracted. There is mild to moderate fatty atrophy of the supraspinatus muscle with moderate to severe fatty atrophy of the infraspinatus muscle. The teres minor tendon and muscle are normal. There is thickening and increased signal of the subscapularis tendon reflecting moderate tendinosis. A more focal area of increased signal intensity is seen at the insertion indicating partial undersurface tearing. There is minimal fatty atrophy of the subscapularis muscle.SUPRASPINATUS OUTLET: There is moderate osteoarthritis of the acromioclavicular joint. A small amount of subacromial subdeltoid fluid is noted, associated with the full-thickness tears described above.GLENOHUMERAL JOINT AND GLENOID LABRUM: The humeral head is high riding and there is minimal posterior translation of the humeral head with respect to the glenoid. Osteoarthritis affects the glenohumeral joint with small articular cartilage defects present. There is attenuation of the labrum reflecting degeneration and degenerative tearing. There is a small joint effusion with scattered foci of intermediate signal intensity likely reflecting mild synovitis.BICEPS TENDON: There is increased signal intensity and thickening of the long head of the biceps tendon along its transition from the rotator interval to the intertubercular groove which reflects tendinosis.
Large rotator cuff tear with additional findings described above.
