Risk Factors for Subsequent Fracture after Osteoporotic Vertebral Compression Fracture

Abstract

Percutaneous vertebroplasty (PVP) is considered an effective treatment method for relieving the pain of osteoporotic vertebral compression fractures (VCFs). Although vertebroplasty is relatively safe and has a low complication rate, however, subsequent fracture after vertebroplasty is not uncommon. A possible increase in risk of new VCF after augmentation is of concern, especially in osteoporotic patients. Furthermore, there is no standard parameter for variables such as optimal cement volume, proper cement injection site, and optimal pattern of cement distribution. Factors that may induce subsequent fracture are also uncertain. The purpose of this study was to evaluate the incidence of and risk factors for subsequent fracture after vertebroplasty.
