The shoulder is the joint with the largest range of motion in the human body.  It is subject to a wide variety of pathologies, because its stabillity is essentially maintained by a complex matrix of ligaments, muscles, and tendons.  Shoulder pain can often be treated with a conservative approach unless the cartilage of the joint between the humerus (the upper arm bone) and the scapula (the shoulder blade) is completely worn, in which case a total shoulder replacement is needed.
