Thirty-two patients with clinical signs and symptoms of the reflex sympathetic dystrophy syndrome (RSDS) of the lower extremities underwent Tc-99m MDP bone scintigraphy. Twenty-three patients had abnormal scan findings consistent with RSDS, while the scans of the remaining nine patients were normal. Of the 23 patients with abnormal scans, 19 demonstrated increased periarticular activity on early and delayed images, while 4 patients demonstrated decreased activity in the affected limb.
