摘　　要：目的研究骨水泥体积分数对单节段骨质疏松性胸腰椎体压缩骨折(OVCF)行经皮椎体成形术(PKP)患者邻近椎体骨折的影响。方法选取2010年3月至2013年9月收治的单节段OVCF并行PKP的患者180例,根据患者术后椎体新发骨折情况分为相邻椎体骨折(AVF)组(32例)、非AVF组(40例)和非骨折组(108例)。基于X线片的价值,计算骨水泥体积分数,比较3组患者注射骨水泥体积、骨水泥体积分数及骨水泥渗透率及手术前后Cobb角和视觉模拟评分(VAS)。结果 AVF组患者注射骨水泥体积及骨水泥体积分数均显著大于非AVF组和非骨折组(P<0.05);AVF组、非AVF组及非骨折组患者骨水泥渗透率分别为34.38%、20.05%和19.67%,AVF组患者骨水泥渗透率显著高于其他2组(P<0.05);3组患者术后Cobb角及VAS评分均显著低于术前(P<0.05)。结论单节段OVCF行PKP患者中邻近椎体骨折发生率及骨水泥渗透率随骨水泥分数的增加而增加,临床应用时应密切注意。Objective To study the effect of bone cement volume fraction on adjacent vertebral body fracture of single segment of osteoporotic thoracolumbar vertebral compression fracture（ OVCF） by percutaneous kyphoplasty（ PKP）. Methods A total of 180 cases of OVCF patients who underwent PKP surgery were selected from March 2010 to September 2013,which were divided into adjacent vertebral fracture（ AVF） group（ 32 cases）,non-AVF group（ 40 cases） and non-fractures group（ 108 cases） according to the patients with new vertebral body fracture. Bone cement was calculated based on the value of Xray film. The injection bone cement volume,bone cement volume fraction and bone cement permeability of the three groups were compared. The changes of Cobb angle and visual analogue scale（ VAS） of the three groups before and after treatment were analyzed. Results The injection bone cement volume and bone cement volume fraction volume of AVF group were significantly greater than those of the other two groups（ P〈0. 05）. The bone cement permeability of AVF group,non-AVF group and non-fracture group were 34. 38%,20. 05% and 19. 67%,respectively. The bone cement permeability of AVF group was significantly higher than that of the other two groups（ P〈0. 05）. The Cobb angle and VAS score of the three groups after treatment were significantly lower than those before treatment（ P〈0. 05）. Conclusion The incidence of AVF in patients with single segmental OVCF and bone cement permeability increases with the bone cement volume fraction increases,which should be pay attention in clinical application.
