A) A small avulsion fracture of the acromion process
Anterior shoulder dislocations are by far the most common type. Reduction should be done as soon as possible as neurovascular injury increases with time dislocated. The most commonly affected nerve is the axillary nerve, which innervates the deltoid region. Impaction fractures caused by the impact of the humeral head against the glenoid fossa during the dislocation are common: impaction fracture of the glenoid rim is a bony Bankart lesion, and of the posterolateral humeral head is a Hill-Sachs lesion. Recurrent dislocation occurs in as high as 50% of patients, and is more common in younger patients < 25 years old.
