Two unique shoulder disorders. Adhesive capsulitis and reflex sympathetic dystrophy syndrome.

Adhesive capsulitis and reflex sympathetic dystrophy syndrome are unique, but not rare, shoulder disorders that occur most often in persons over 50 who have experienced recent trauma. Although the etiology and nature of the disorders are not fully understood, therapy is often effective when instituted early. Adhesive capsulitis is a self-limited disorder, and patients usually recover in time. Reflex sympathetic dystrophy syndrome, however, can cause serious impairment if not treated promptly. Early mobilization of persons at risk may help reduce the incidence of the disorders.
