Shoulder fractures can result from a fall on the shoulder, a motor vehicle accident, contact sports, etc.
The shoulder is a complex joint connecting the arm to the body. The shoulder bones include the humerus (upper arm bone), the scapula (shoulder blade) and the clavicle (collarbone).The upper end of the humerus has a ball-like shape that connects with the socket of the scapula, called the glenoid. Disruption of any of the parts of the shoulder can create difficulty with its function.
