Abstract
This study was performed to assess the feasibility; safety; and clinical outcome of percutaneous transpedicular polymethylmethacrylate vertebroplasty (PTPV) for the treatment of vertebral compression fractures causing refractory pain. The clinical and rediological data of 295 vertebrae in 218 patients; who underwent PTPV for vertebral compression fractures between August 2000 and June 2004; were retrospectively reviewed. Imaging and clinical features were analyzed; including the age; sex; bone marrow density (BMD) score; symptom duration; number of collapsed vertebra; compression grade of vertebra; leakage of bone cement; volume of injected bone cement; vertebroplasty complication; and clinical outcome. The mean age was 69.7 yaers (58-87 years). The average BMD score was-3.62; indicating severe osteoporosis. The mean duration of follow-up was 7.3 months (3-14 months). Symptoms were improved in 81.2%; worse in 0.9% and the same in 17.9%. Extrusion of polymethylmethacrylate cement beyond the confines of the vertebral body was observed in 34 cases (11.5%); but set in no serious complications. PTPV is safe and feasible treatment for patients with vertebral compression fractures and provides significant early relief in a high percentage of patients with refractory pain and prevents vertebral collapse.
