AJNR Am J Neuroradiol 21:1807–1812, November/December 2000 Value of Bone Scan Imaging in Predicting Pain Relief from Percutaneous Vertebroplasty in Osteoporotic Vertebral Fractures

BACKGROUND AND PURPOSE: Patient selection for percutaneous vertebroplasty is often complicated by the presence of multiple fractures or non-localizing pain. Our purpose was to determine whether increased activity revealed by bone scan imaging is predictive of a positive clinical response to percutaneous vertebroplasty. METHODS: A retrospective chart review conducted at our institution yielded 28 vertebro-plasty treatment sessions that had been performed after obtaining bone scan imaging for pain-ful, osteoporotic compression fractures in 27 patients. Thirty-five compression fractures were treated during these 28 treatment sessions. In all cases, increased activity was revealed by bone scan imaging before treatment with vertebroplasty. Positive outcome was defined as subjective decrease in pain severity and/or increased level of patient mobility. RESULTS: Subjective pain relief was noted in 26 (93%) of 28 treatment sessions. In 14 (100%) of 14 cases with quantifiable pain levels, pain improved at least 3 points on a 10-point scale (range of improvement, 3–10 points; mean improvement, 7.4 points). Among the remain-ing 14 treatment sessions in which patients were unable or unwilling to quantify pain severity, the pain relief was described as complete or excellent pain relief in 11 (78%) of 14 cases.
