ObjectiveTo explore the cause, clinical treatment and prevention of secondary adjacent vertebral fractures after percutaneous kyphoplasty(PKP) for the treatment of osteoporotic vertebral compression fractures(OVCFs).Methods A retrospective analysis from February 2012 to February 2014 were applied on the 32 cases of reoperation of PKP performed for 32 patients who developed the secondary adjacent vertebral fractures after initial PKP for the treatment of OVCFsdue to the.Results All patients were successfully completed of surgery and toletated the procedure well with immediate relief of their back pain in 2d hours. No complications occurred. The mean VAS score decreased from preoperative(7.00±0.76)to postoperative scores(2.80±0.52);The mean Oswestry scores decreased from 47.15±1.63 preoperatively to 25.55±1.85 postoperatively. there were signifi cant differences between preoperation and postoperation(P<0.05).Conclusion PKPtechnology holds the treatment of osteoporotic vertebral compression fractures(OVCFs)with postoperative incidence of adjacent vertebral fractures,and shows a trend of increasing gradually,again with the clinical curative effect of treatment of PKPholds the same satisfactory effect.%目的：探讨椎体后凸成形术（PKP）骨质疏松性椎体压缩性骨折（OVCFs）术后继发邻椎骨折的原因、临床疗效及预防措施。方法回顾性分析2012年2月至2014年2月OVCFs32例行PKP治疗后继发邻椎骨折的患者进行再次PKP治疗的临床资料。结果32例患者均顺利完成手术，术后2d内疼痛均缓解，未发现并发症。疼痛视觉模拟评分（VAS）由术前（7.00±0.76）分减至术后（2.80±0.52）分；Oswestry评分由术前平均（47.15±1.63）分减至术后（25.55±1.85）分；差异均有统计学意义（P<0.05）。结论 PKP术治疗骨质疏松性椎体压缩性骨折（OVCFs）术后伴随一定的邻椎骨折发生率，并呈逐渐升高趋势，再次用PKP术治疗同样取得满意的临床疗效。
