Info

CT confirms anterior dislocation and large Hill-Sachs lesion with large piece of bone missing from superolateral humeral head, with anteroinferior glenoid margin "engaging" the Hill-Sachs defect. No bony Bankart lesion. Small osseous fragments which likely represent fragments of the humeral cortex. There is hematoma around the scapula.

Case Discussion

Recurrent anterior dislocations can lead to the formation of a large Hill-Sachs lesion, as seen here.
