Reason: recurrent shoulder dislocation History: recurrent shoulder dislocation. ROTATOR CUFF: The rotator cuff tendons and muscles appear normal.SUPRASPINATUS OUTLET: No fluid or gadolinium is present in the subacromial subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral joint alignment is within normal limits. There is a full-thickness defect of the articular cartilage involving the anterior inferior glenoid measuring approximately 5 mm in AP dimension and at least 1 cm in CC dimension. The adjacent anterior inferior labrum is attached to the glenoid without gadolinium interposition to indicate a tear. Although we see no gadolinium entering the posterior labrum, the posterior labrum is slightly deformed with prominent undercutting by intermediate signal which could represent a chronic tear. Furthermore, the adjacent inferior labrum (from the 5 to 7:00 positions) appears attenuated. What we presume to be the anterior band of the inferior glenohumeral ligament appears to attach somewhat more superomedial than usual, but this is of uncertain clinical significance.BICEPS TENDON: The tendon of the long head of the biceps appears normal. ADDITIONAL
Findings compatible with prior dislocation including a Hill-Sachs deformity and full-thickness articular cartilage loss along the anterior inferior glenoid. Although the anterior inferior labrum appears attached to the glenoid, slight deformity of the posterior labrum and attenuation of the inferior labrum may reflect labral tearing. Furthermore, the presumed anterior band of the inferior glenohumeral ligament appears to attach to the glenoid superomedial to usual, but the clinical significance of this is uncertain.
