Long-term follow-up of percutaneous vertebroplasty in osteoporotic compression fracture: Minimum of 5 years follow-up

Abstract

Study Design: This was designed as a retrospective study. Purpose: We assessed the radiographic and clinical outcome of patients who underwent percutaneous vertebroplasty (PVP) in osteoporotic compression fractures with a minimum of 5 years follow-up. Overview of Literature: Percutaneous vertebroplasty is effective surgical method for treating osteoporotic compression fracture. Methods: Between January 2000 and August 2005, 159 patients were treated with PVP for osteoporotic compression fracture at our department; 43 patients died during follow-up, and 69 patients (121 vertebras) were available for follow-up for over 5 years. We analyzed the clinical and radiologic outcome including cement feature. Results: The mean follow-up period was 5.7 years. Clinical outcome by mean visual analogue scale (VAS) score revealed a decreased 4.9 points perioperatively. A decreased score was maintained over 5 years in 46% of patients. A new adjacent vertebral fracture was documented by 33 vertebral bodies in 22 patients. During the follow-up period,43 patients (38%) in 112 patients died. Anterior body heig ht in the last follow-up was improved about 0.3 mm compared with the preprocedural value, but was not statistically significant. Also, the focal kyphotic angle was reduced from 12.3° at the preprocedural state to 11.7° at the postprocedural state,but was not statistically significant (p > 0.05). Conclusions: PVP for osteoporotic compression fracture is an efficient procedure for pain relief by long term follow-up. The cement injected vertebrae showed stable radiologic progression without significant changes in vertebral heig ht or kyphotic angle. © 2012 by Korean Society of Spine Surgery.
