How the Shoulder Works

The shoulder is made up of three main bones: the collarbone (clavicle), the shoulder blade (scapula) and the upper arm bone (humerus). The purpose of the shoulder is to position the arm and hand in space. Although the shoulder is often referred to as a “ball and socket” joint, in reality, it more closely resembles a golf ball sitting on a tee wrapped in muscles and tendons (the rotator cuff). For this reason, the shoulder is the most mobile joint in the human body, allowing people to reach overhead, behind their back, across the body, and out to the side. This freedom of motion makes it possible to throw a ball, swing a golf club or tennis racket, get dressed, perform personal hygiene, or reach for something on a high shelf.

While the unique evolutionary shape of the shoulder allows for this broad range of motion, this often comes at a price of: instability, soft tissue injuries and fractures, or degenerative joint disease (i.e. arthritis).

At The Orthopaedic Institute (Formerly Palm Beach Hand to Shoulder), Dr. Veronica Diaz specializes in providing targeted care of the shoulder. Your consultation with her will involve establishing the cause of your symptoms or limitations. It will also include coming up with a tailored treatment plan that considers your activity demands and goals, the condition of your shoulder, and your general health status.
