Sudeck's Atrophy

Other Names : Reflex Sympathetic Dystrophy (RSD), Reflex Sympathetic Dystrophy Syndrome (RSDS), Complex Regional Pain Syndrome (CRPS) type I,
Reflex Sympathetic Dystrophy Syndrome (RSDS) is relatively common and has been reported to occur after 5% of all traumatic injuries. It may occur following fractures to the extremities, joint sprains or following surgery. It has also been reported following immobilisation and frostbite. It is thought to be caused by a dysfunction of the sympathetic nervous system, which is involved in the regulation of blood supply to the affected part. The condition is often not diagnosed until sometime after the initial symptoms begin.

Causes

• It may occur spontaneously (i.e. without any cause) -but more commonly it follows trauma (fractures, ligament and muscle strains, nerve or soft tissue injuries) which may seem trivial.
• It is believed to be due to prolonged immobilisation following the injury.
• It can also be associated with medical conditions - diabetes, stroke/heart attack, thyroid disease, cancer, infections.

Symptoms

The symptoms are variable and will present themselves differently from patient to patient. The main symptoms begin with a generalised burning pain; this is usually followed by changes in the condition of the skin, which may become shiny. In severe cases, the affected body part may swell and, due to sympathetic nervous system dysfunction, the body part may perspire more than usual. Because of the pain the patient may not want to move the injured part. This leads to muscle wastage and a viscious cycle where stiffness and pain become worse. If the condition persists there may be adverse changes to the condition of the underlying bone.
