Patient with history of right shoulder dislocation x15, most recent 3 weeks ago, evaluate for labral tear. ROTATOR CUFF: There is focal tearing of the undersurface of the supraspinatus tendon at approximately 1.5 cm proximal to its insertion site. A thin linear collection of gadolinium extends distally within the substance of the tendon from this tear, suggesting a component of focal delamination. Overall this tearing affects less than 50% of the width of the tendon and we see no full thickness tearing of the tendon. The supraspinatus muscle is intact. There is also a small focal undersurface tear of the infraspinatus tendon immediately proximal to its insertion site, best seen on the sagittal oblique series 6. The infraspinatus muscle is intact. The teres minor tendon and muscle appear intact. The subscapularis tendon and muscle appear intact.SUPRASPINATUS OUTLET: The acromioclavicular joint appears normal and there is no fluid in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is normal. However, the majority of the anterior labrum is absent, including the anterior inferior labrum. The anterior inferior glenohumeral ligament is not visualized on the ABER sequences. Posterior labrum is intact. We suspect that there is tearing of the anterior superior labrum, but posteriorly the superior labrum appears intact. There is slight depression of the posterior aspect of the humeral head indicating a Hill-Sachs deformity.BICEPS TENDON: Tendon of the long head of the biceps appears normal.
Nonvisualization of the anterior labrum and Hill-Sachs deformity, compatible with stated history of recurrent shoulder dislocations.
