Prognostic value of triple phase bone scanning for reflex sympathetic dystrophy in hemiplegia.
    Archives of physical medicine and rehabilitation, 1993, Volume: 74, Issue:7

    Twenty-two patients with cerebral vascular accident (CVA), clinically confirmed by head computed tomography, were observed for symptoms of the reflex sympathetic dystrophy syndrome (RSDS). All patients received triple phase bone scans; 16 scans were positive for RSDS. Patients with negative scans had no symptoms of RSDS. Five patients with positive scans had RSDS symptoms at the time of bone scanning. Seven of 11 patients with positive scans but no symptoms of RSDS at the time of bone scan developed symptoms of RSDS within six months. We found a significant relationship between positive bone scans and the subsequent development of RSDS (p < 0.01). Considering only those patients who were asymptomatic for RSDS at the time of bone scanning, we found bone scanning to be a good predictor for the future development of clinical RSDS. We found the correlation between positive bone scans and the subsequent development of clinical RSDS in previously asymptomatic individuals to be statistically significant (p < 0.05). We conclude that bone scans may be a good predictor of patients at risk for developing clinical RSDS after CVA.

Three-phase bone studies in hemiplegia with reflex sympathetic dystrophy and the effect of disuse.
    Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1984, Volume: 25, Issue:4

    Eighty-five patients with cerebral vascular accidents were assessed with three-phase bone scintigraphy of the hands and with whole-body delayed bone imaging. Nine patients (10%) had normal three-phase bone images. Fifty-five patients (65%) showed decreased blood flow and blood-pool images of the hands and wrists with normal delayed bone scintigrams, indicating the effect of paralysis or disuse. Twenty-one patients (25%) had diffuse increased uptake with periarticular accentuation, felt to be bone-scintigraphic evidence of reflex sympathetic dystrophy of the hands and wrists; in two patients this occurred before its clinical appearance. Thirteen of the 21 reflex sympathetic dystrophy syndromes (RDS)-involved limbs (62%) had increased blood flow, whereas 8 (38%) had decreased flow. Gross limb blood flow appears to be related to the degree of muscle activity, but flow may be altered by the presence of sympathetic changes. A possible dissociation between whole-limb flow and bone blood flow in paralyzed limbs involved with RDS is discussed. The elbow was involved in only one case, and a true "shoulder-hand" distribution was seen in only 11 of 21 cases (52%). Five patients (6%) had leg involvement on whole-body imaging. Traumatic synovitis of the wrist, and trauma to subluxed shoulders, could be recognized on the delayed study.
