Reflex sympathetic dystrophy. Timely diagnosis and treatment can prevent severe contractures

Reflex sympathetic dystrophy is a clinical syndrome consisting of persistent burning pain and varying degrees of vasomotor and trophic changes in an extremity after trauma. Although several mechanisms have been proposed, none have been universally accepted. Historically, treatment has involved sympathetic blockade or sympathectomy to prevent the proposed sympathetic hyperactivity. However, only a limited number of controlled studies have been conducted, and results have been controversial. The cornerstone of treatment is physical therapy to prevent the severe contractures that can result.
