The shoulder is not a ball in socket joint; it is a ball on a saucer joint. This gives it incredible range of motion but it also makes it prone to instability. It is reliant on the muscles and ligaments for its stability and proper function.
Most shoulder problems are biomechanical problems that result when the muscles and ligaments aren’t working well together. These problems usually respond well to a proper rehabilitation program.
Other common problems of the shoulder result from irritation and inflammation from overuse and wear and tear. These problems can be resolved with medications, injections, and a proper exercise program.
Traumatic injuries of the shoulder such as fractures and dislocations are obviously more severe problems that often require surgery for repair and recovery.
