Prognostic value of triple phase bone scanning for reflex sympathetic dystrophy in hemiplegia.
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.
