摘要
目的:探讨PVP/PKP术后非手术椎体再发骨折的发生率及相关危险因素。方法:回顾性分析2009年1月至2013年12月收治的胸腰段椎体的压缩性骨折首次行单节段椎体PVP/PKP治疗的患者452例,根据术后非手术椎体是否再发骨折分为骨折组(64例)和非骨折组(388例)。通过年龄、性别、骨水泥注入量、椎体局部后凸纠正角度、手术方式、手术椎体节段、有无骨水泥外渗、围手术期有无行抗骨质疏松治疗等因素的统计,探讨术后非手术椎体再发骨折的相关危险因素。结果:骨折组在骨水泥外渗发生率、围手术期抗骨质疏松药物使用率方面明显高于非骨折组(P<0.01),骨折组在术后伤椎局部后凸Cobb角纠正角度方面大于非骨折组(P<0.05)。结论:骨水泥外渗、伤椎局部后凸Cobb角纠正过度、围手术期未行抗骨质疏松治疗均明显提高PVP/PKP术后非手术椎体再发骨折的发生率。
Objective：To investigate the incidence and the relevant risk factors of non-surgical vertebral fractures following percutaneous vertebroplasty and kyphoplasty （PVP/PKP）. Methods： This study retrospective analyzed the 452 patients who were diagnosed with thoracolumbar vertebral compression fractures and underwent PVP/PKP for single level from Jan. 2009 to Dec. 2013. They were divided into two groups depending on whether there were non-surgical vertebral fractures after surgery. The possible correlative factors,including the patients＇ age, sex, bone cement injection volume, correction of vertebral Cobb＇s angle, surgical approach （PVP or PKP）, vertebral segments for operation, bone cement extravasa- tion,and antiosteoporotic medications during perioperation were analyzed. Results：The rate of bone cement extravasation and antiosteoporotic medications during perioperation in refracture group was higher than that in non-refracture group （P 〈0.01）. The correction of vertebral Cobb＇s angle in refracture group was greater than that in non-refracture group （P〈 0.05）. Conclusion：This study suggested that bone cement extravasation, excessive correction of the vertebral Cobb＇s angle and absence of antiosteoporotic medications during perioperation may significantly increase the incidence of non-surgical vertebral fractures following PVP/PKP.
