The aim of this study was to estimate a prevalence of vertebral body compression fractures (VCFs) on previously
percutaneous vertebroplasty (PVP) and Kyphoplasty and to evaluated risk factors related to new VCFS and to prevention of new VCFs. A retrospective study was conducted. PVPs were carried out between Feb. 2001 and Oct. 2005 for 103 patients (134 levels) with symptomatic osteoporotic vertebral fractures that had not responded to conservative therapy. The symptomatic levels were identified by correlating the clinical symptom with MRI findings. Risk factors were age, sex, levels, amount and variety of cement, approach, preoperative T-score and kyphoplasty. We concluded that a number of level (p = 0.02), approach method (p = 0.034), BMD (p = 0.004) and the amount of cement (p = 0.001) were significants in cross-sectional analysis. Therefore, it was needed to prevent of refracture, as long as even distribution of injected bone cement amount in vertebroplasty or kyphoplasty, essentially.
