Recurrent Shoulder Dislocation MRI



Evidence of deformed humeral head with defect measuring depth of around 5mm in the posterosuperior aspect of the humeral head likely consistent with hill sach's deformity.This type of injury is caused by impaction of the humerus against the anterior rim of the glenoid cavity. 
 Evidence of the cranial migration of the deformed humeral head reducing the acromiohumeral space and showing some impingement of the myotendinous junction of the supraspinatus tendon. There is evidence of detached & displaced anterior labrum from the glenoid rim  along with stripping of the scapular periosteum medially which likely indicates associated bankart's lesion, possibly perthes variant.
There is increased fluid in the glenihumeral joint along with fluid along the biceps tendon. Small osteocartilagenous defect is also noted in the anteromedial  humeral head which may indicate associated bony defect due to humeral avulsion of glenohumeral ligament (HAGL) which may further contribute to shoulder instability.

Shoulder Joint : Most common joint to undergo dislocation / traumatic dislocation / recurrent dislocation.

And Most common is the Anterior Dislocation - PreCoracoid = SubCoracoid.


Recurrent dislocation is not associated with Rotator Cuff Tear. (MCQ)
