Presentation
Recurrent shoulder dislocations. Dislocated again and not reducible in ED.
Patient Data



The humeral head has dislocated anteriorly, and there is a large wedge-shaped defect in the superolateral humeral head.








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.
