Abstract
PURPOSE: To evaluate safety and efficacy of fluoroscopy-guided percutaneous vertebroplasty (PVP) for painful osteoblastic spinal metastases. MATERIALS AND METHODS: PVP was performed in 39 consecutive patients (median age, 60.1 y ± 9.5) with 51 osteoblastic metastatic spinal lesions; 14 patients had pathologic fractures. The patients were followed for 3-30 months (average, 14.5 mo ± 7.4). Visual analog scale (VAS), Oswestry Disability Index (ODI), and Karnofsky performance scale (KPS) were used to evaluate pain, quality of life, and performance status before the procedure and at 3 days and 1, 3, 6, 12, and 18 months after the procedure. RESULTS: Technical success was achieved in all patients. Minimal follow-up time was 3 months. Mean VAS scores declined significantly from 7.4 ± 1.1 before the procedure to 2.5 ± 0.9 by day 3 after the procedure and were 2.1 ± 1.1 at 1 month, 2.0 ± 1.1 at 3 months, 1.9 ± 1.1 at 6 months, 1.8 ± 0.9 at 12 months, and 1.7 ± 0.7 at 18 months after the procedure (P < .001). ODI and KPS scores also changed after the procedure, with significant differences between baseline scores and at each follow-up examination (P < .001). Extraosseous cement leakage occurred in 15 cases without causing any clinical complications. CONCLUSIONS: PVP is a safe and effective treatment for painful osteoblastic spinal metastases. It can relieve pain, reduce disability, and improve function.
