34-year-old male with recurrent dislocations with shoulder pain for years. Evaluate for labral tear. Several sequences are limited by patient motion artifact.ROTATOR CUFF: There is increased signal intensity along the undersurface of the distal supraspinatus tendon, just proximal to its insertion on the greater tuberosity, indicating focal tendinosis or undersurface tearing with a small erosion/cyst in the underlying humeral head. This involves less than 50% of the tendon width and measures approximately 5 mm in the longitudinal dimension. We see no full-thickness tear. The infraspinatus muscle and tendon appear intact. The subscapularis and teres minor muscles and tendons appear intact.SUPRASPINATUS OUTLET: There may be minimal osteoarthritis of the acromioclavicular joint which otherwise appears normal. There is a trace amount of fluid within the subacromial-subdeltoid bursa, but no gadolinium.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is a bucket-handle type tear of the superior labrum with additional full-thickness tearing that extends into the anterior labrum and partial-thickness detachment (Perthes-type lesion) of the anteroinferior labrum. There is full-thickness articular cartilage loss along the torn anterior labrum. The posterior labrum appears intact. The glenohumeral joint alignment is within normal limits.BICEPS TENDON: The tendon of the long head of the biceps appears intact. There is a small focus of low signal intensity within the biceps tendon sheath which could represent a small cartilage fragment, but this is equivocal.
1. Labral tear as described above with adjacent degeneration of the articular cartilage of the glenoid.2. Focal tendinosis and/or tearing of the undersurface fibers of the distal supraspinatus tendon.3. Equivocal loose cartilage fragment within the tendon sheath of the long head of the biceps tendon.
