Prompt and appropriate treatment of a dislocated shoulder — when the head of the upper arm bone is completely knocked out of the shoulder socket — can minimize risk for future dislocations as well as the effects of related bone, muscle and nerve injuries, according to a literature review.
The shoulder has the greatest range of motion of any joint in the human body and is the most common site for a full or partial dislocation. Shoulder dislocations are classified as “traumatic” or “atraumatic.” Up to 96 percent of dislocations are traumatic, occurring most often during contact sports or when someone falls onto an outstretched hand. Atraumatic dislocations — when the shoulder starts to slip part way out without trauma — can cause limited shoulder movement in multiple directions.
