Shoulder & Elbow


The shoulder is the most mobile joint in the human body, capable of a nearly 360 degree range of motion. However, the complex mechanics of the shoulder make it vulnerable to injury. According to the American Academy of Orthopaedic Surgeons, an estimated 4 million people seek medical assistance for shoulder and upper arm strains and sprains each year.

Shoulder injuries, which affect people of all ages, can be caused by sports activities that involve overhead motion like swimming, tennis, pitching and weightlifting. People who do repetitive overhead movements in everyday life like painting, construction, and gardening are also susceptible to shoulder conditions ranging from sprains, strains and arthritis to tendonitis, bursitis, frozen shoulder and torn rotator cuffs.

The shoulder joint is made up of the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper-arm bone). The shoulder joint, or glenohumeral joint, is a ball-and-socket joint that helps the shoulder move forward and backward and makes it possible for the arm to move in a circular motion and lift away from the body.


The elbow joint links the upper arm bone (humerus) and the two bones of the lower arm (ulna and radius). The elbow joint operates like a door swinging on a hinge and also performs twisting and rotating motions. The elbow is also made up of muscles, nerves and tendons that connect the tissues between muscles and bones.
