End-stage reflex sympathetic dystrophy.

Reflex sympathetic dystrophy is an automatic dysfunction that occasionally complicates healing after trauma or surgery. The syndrome is characterized by pain, swelling, stiffness, and discoloration often out of proportion to the original injury. Early diagnosis and appropriate treatment are the most important factors in the successful outcome of this disabling condition. A case of longstanding, previously untreated reflex sympathetic dystrophy secondary to a minor injury is presented.
