Recurrent Shoulder Dislocation-MRI

25 yr old male with recurrent dislocation of shoulder ( anterior and posterior)

FINDINGS--There is evidence of mild subluxation at the glenohumeral joint with cranial migration of humeral head. Also noted in fluid distension involving the joint capsule with joint capsule laxity.
There is evidence of altered signal intensity involving the anteroinferior glenoid labrum suggestive of avulsion tear. Altered marrow signal is noted in inferior glenoid rim. Posterior glenoid labral rim is rolled up. Fluid is noted along the biceps tendon. Rotator cuff muscles including subscapularis & infraspinatus appears lax & show mild reduction in bulk. No obvious rotator cuff tear is identified. Bony defect is noted in the posterosuperior aspect of humeral head. There is fluid is subcoracoid bursa. Acromial process seen normally with reduced acromio- humeral space. Acromio clavicular joint is normal.

IMPRESSION--Fluid distension in the joint capsule with anterior & posterior labral tear (bankart’s lesion) with cranial subluxation at glenohumeral joint with laxity in rotator cuff muscles with small defect in posterior humeral head (?hill sach’s lesion).
