Bony lesions after anterior shoulder dislocation

A woman in her 60s experienced severe right shoulder pain and restricted shoulder motion after she fell on her outstretched right hand. On clinical examination the right shoulder contour was flattened and the right arm was in a fixed, abducted, and externally rotated position. Sensation over the lower deltoid region and other distal neurovascular function was intact. Radiography showed anterior shoulder dislocation without obvious fracture to the humerus (fig 1). The patient had no history of shoulder injury before this incident. Closed reduction was performed by traction and counter-traction under analgesia and sedation. The pain subsequently improved and neurovascular function remained intact. Post-reduction radiography was performed (fig 2).
