A<unk>  occurs when the humerus separates from the scapula at the glenohumeral joint.  As the most maneuverable joint in the human body, the shoulder is the joint most vulnerable to dislocation.  Approximately half of major joint dislocations seen in emergency departments are of the shoulder.  Partial dislocation of the shoulder is referred to as subluxation.
