ABSTRACT
Objective To investigate the influential factors for refracture of the adjacent vertebral body following percutaneous vertebroplasty (PVP) treatment of patients with osteoporotic vertebral compression fractures (OVCFs).Methods A retrospective analysis was conducted on OVCFs patients undergone mono-segmental PVP from July 2007 to March 2010.Patients' age,gender,bone density,bone cement infusion dosage,bone cement leakage and pre-and post-operative fracture reduction were documented.Kaplan-Meier remaining rate curve was used to predict the trend of time to refracture.The related factors for adjacent vertebral body refracture following PVP were analyzed.Results In all,216 patients (98 males and 118 females; age range of 55-76 years,average 65.4 years) were enrolled in this study.Follow-up lasted for 12-18 months.Ninety-two patients sustained refracture including 68 patients with refracture of the adjacent vertebral body.Refracture of the adjacent vertebral body presented time-concentrated tendency and 66% (45/68) occurred within 100 days followed by a notably lower incidence.Whereas the time to refracture of the non-adjacent vertebral body was not obviously centralized.Bone cement infusion dosage and vertebral body reset condition were strongly associated with the refracture incidence of the adjacent vertebral body,while opposite results were observed in regard of age,gender,bone density and bone cement leakage (or not).Conclusion PVP predisposes OVCFs patients to refracture of the adjacent vertebral body and its influential factors may be associated with bone cement infusion dosage and vertebral body reduction condition.
