The shoulder consists of three bones which come together to form the joint: the humerus (the arm bone), the clavicle or collarbone, and the scapula at the glenoid (the shoulder blade). When an individual sustains a shoulder fracture, any of these three bones may be damaged or injured.

The majority of people who suffer from a fractured shoulder are diagnosed with a fracture of the proximal humerus. A proximal humerus fracture is an injury to the top of the humerus, or arm bone, which forms the ball of the ball-and-socket shoulder joint. Determining the appropriate treatment for the type of injury depends on the specific injury.
