Comparison of multi-level puncture versus single-level puncture percutaneous vertebroplasty for treatment of multiple-level osteoporotic vertebral body compression fractures in senile patients / 中华创伤骨科杂志

ABSTRACT

Objective To compare the curative effects of multi-level puncture versus single-level puncture percutaneous vertebroplasty(PVP) for treatment of multiple-level osteoporotic vertebral body compression fractures(OVCF) in senile patients.Methods From June 2008 through November 2014,89 senile patients with fresh multiple-level OVCF underwent PVP guided by C-arm fluoroscopy in prone position.Of them,51 received PVP in which the vertebrae of multiple levels were simultaneously punctured for bone cement injection while the other 38 received PVP in which the vertebrae of multiple levels were punctured one by one for bone cement injection.The 2 groups were compatible with no significant differences in preoperative demographic data (P ＞ 0.05).The 2 groups were compared in terms of visual analgesic scale (VAS),operation time for a single vertebra,fluoroscopy times for a single vertebra,bone cement injection amount for a single vertebra,and extraosseous cement leakage.Results PVP procedures were successful in both groups without serious complications.The VAS scores in both groups at 2 days post-operation were significantly lower than those at pre-operation(P ＜ 0.05).The operation time and fluoroscopy times for a single vertebra in the multi-level puncture PVP group were significantly less than those in the single-level puncture PVP group (P ＜ 0.05).There were no significant differences between the 2 groups in bone cement injection amount for a single vertebra or extraosseous cement leakage (P ＞ 0.05).Conclusions The curative effects of multi-level puncture and single-level PVP are satisfactory for senile OVCF,but multi-level puncture PVP may lead to less operation time and less X-ray exposure.
