24-year-old male status post anterior shoulder dislocation now with pain, evaluate for labral tear. ROTATOR CUFF: The rotator cuff is within normal limits. The acromioclavicular joint is normal and we see no fluid within the subacromial/subdeltoid bursa.SUPRASPINATUS OUTLET: No significant abnormality noted.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is within normal limits. There is slight deformity of the anterior inferior glenoid from the three o'clock to six o'clock position that we suspect represents a thin crescentic healing Bankhart fracture. There is deformity of the anterior inferior labrum along the suspected fracture that likely represent injury to the labrum; however, we see no fluid separating the labrum from the underlying bone, even on the ABER sequence. There is a small cleft in the articular cartilage of the anterior glenoid as well as a 7 mm linear focus of intermediate signal intensity along the surface of the anterior inferior glenoid which may represent a cartilage flap or fragment. Gadolinium partially separates the anterior superior labrum from the underlying bone and we are uncertain if this represents a tear or sublabral foramen. There is a full-thickness chondral defect along the posterior superior aspect of the humeral head. Small foci of intermediate signal intensity layering dependently in the glenohumeral joint likely represent cartilage fragments. BICEPS TENDON: The long head of the biceps is intact. There is a 5 mm focus of intermediate signal intensity in the biceps tendon sheath, likely representing an additional cartilage fragment.
Findings indicating prior anterior dislocation as detailed above, including deformity of the anterior inferior glenoid and labrum likely representing a healing Bankhart fracture with additional cartilage defects and fragments as described above.
