Posterior shoulder dislocation with reverse Hill Sachs defect and reverse Bankart lesion
Presentation
Pain post dislocation.
Patient Data











Reduced acute posterior shoulder dislocation with large reverse Hill–Sachs defect that involves approximately 40% of the articular surface of the humeral head. There’s also a posterior labral reverse Bankart lesion in the 6-9 o'clock position with joint effusion and small anterior instertional supraspinatus tendon tear. Intact posterior glenoid rim, intact lesser tubercle, and subscapularis tendon. Normal the long head of biceps tendon.
Case Discussion
Posterior shoulder dislocation can cause bipolar lesions with an anterior humeral head impression fracture, the “reverse Hill-Sachs defect”, and injuries of the posterior labrum and/or fractures of the posterior glenoid rim ("reverse Bankart lesion"). The reverse Hill-Sachs defect is a risk factor for re-dislocation.
