Surgery on extremities with reflex sympathetic dystrophy.

Abstract

Surgery on extremities suffering from reflex sympathetic dystrophy (RSD) is generally avoided because it is presumed that RSD will recur or worsen. In order to study this problem we analyzed our patients. The affected limb of 47 patients suffering from RSD was operated on for various reasons. If possible, the operation was postponed until the signs and symptoms of RSD decreased at rest and perfusion of the affected limb was optimized; tourniquet haemostasis was avoided, and perioperative intravenous infusion of mannitol was administered. Recurrence of RSD was seen in 6 patients (13%). This recurrence was mild and temporary in 5 patients, but serious and permanent in 1 patient. Surgery on limbs suffering from RSD is not as dangerous as widely believed, but one should be aware of the risk of recurrence of RSD when surgery is being considered.
