Background: Percutaneous vertebroplasty is effective surgical method for treating osteoporotic compression fracture. We assessed the radiographic and clinical outcome of patients who underwent percutaneous vertebroplasty (PVP) in osteoporotic compression fractures with a minimum of 7 years follow-up retrospectively.

Methods: Between January 2000 and August 2007, 253 patients were treated with PVP for osteoporotic compression fracture at our department; 81 patients died during follow-up and 101 patients (177 vertebras) were available for follow-up for over 7 years. We analysed the clinical and radiologic outcome including cement feature.

Results: The mean follow-up period was 7.9 years. Clinical outcome by mean visual analogue scale (VAS) score revealed a decreased 4.9 points perioperatively. A decreased score was maintained over 7 years in 46% of patients. A new adjacent vertebral fracture was documented by 55 vertebral bodies in 35 patients. During the follow-up period, 81 patients (44.5%) in 182 patients died. Anterior body height 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). Out of the 101 cases, the 89 cases for whom the cement was injected into the vertebral body were kept in a stable condition. Seven cases of radiolucent line with decreased bone density in the adjacent area of cement and 5 cases of cement cracks accompanied with vertebral collapse were observed.

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 height or kyphotic angle.
