Shoulder Injuries

The shoulder joint is made up of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone). Injury to these bones and their surrounding ligaments and muscles is most often sustained during sports with repetitive overhead motions such as pitching in baseball or many swimming strokes.
Frozen shoulder occurs when joint inflammation causes the shoulder ligaments to swell and thicken, resulting in scar tissue that leaves less space for the ball of the shoulder joint to rotate in its socket.
