Description: Mechanism of anterior dislocations:
- combination of abduction, extension, and a posteriorly directed force applied to the arm;
- humeral head is driven anteriorly, tearing the shoulder capsule, detaching the labrum from the glenoid, and producing a compression frx of the humeral head;
- arm position during the traumatic episode leads to variations of anterior dislocation:
