经皮椎体成形术与经皮椎体后凸成形术治疗骨质疏松性椎体压缩骨折的疗效比较

目的：比较经皮椎体成形术（ PVP）和经皮椎体后凸成形术（ PKP）治疗骨质疏松性椎体压缩骨折的疗效。方法选择70例骨质疏松性椎体压缩骨折患者，采用随机数字表法分为观察组和对照组各35例，分别采用PKP和PVP治疗。观察并比较两组术后椎体压缩率、Cobb＇s角恢复情况、疼痛缓解及并发症发生情况。结果术后1个月，两组患者椎体压缩率、Cobb＇s角均较治疗前改善（对照组t＝2．39、2．21，观察组t＝3．52、2．89，均P＜0．05），且观察组改善幅度明显优于对照组（t＝2．34、2．14，均P＜0．05）。两组患者疼痛情况均较术前明显改善（t＝3．91、3．84，均P＜0．05），但两组改善幅度差异无统计学意义（t＝0．21，P＞0.05）；观察组术后发生并发症占5．7％（2/35），低于对照组的22．9％（8/35）（χ2＝4．20，P＜0．05）。结论采用PVP及PKP治疗骨质疏松性椎体压缩骨折均可显著缓解患者的疼痛，但PKP治疗更有利于椎体高度及Cobb＇s角的恢复，且并发症更少，安全性更佳。

Comparison of curative effect between percutaneous vertebroplasty and percutaneous kyphoplasty osteoporot-ic vertebral compression fractures

Objective To discuss the curative effect between percutaneous vertebroplasty （ PVP） and percu-taneous kyphoplasty （ PKP） to treat osteoporotic vertebral compression fractures .Methods 70 cases with osteoporotic vertebral compression fractures were selected and divided into the observation group and control group at random ,who were treated with PKP and PVP respectively .Postoperative vertebral compression rate ,Cobb＆#39;s angle recovery,relief of pain and occurrence rate of untoward effect of patients in the two groups were observed and compared .Results The vertebral compression rate and Cobb＆#39;s angle recovery of patients in the two groups one month after the operation were improved than before（t=2.39,2.21,3.52,2.89,all P〈0.05）,and the improvement rate in the observation group was much higher than that in the control group （t=2.34,2.14,all P〈0.05）.The relief of pain of patients in the two groups was greatly improved than before （t=3.91,3.84,all P〈0.01）.After comparing the improvement rates of relief of pain,no obvious statistical differences appeared （t=0.21,P〉0.05）.The postoperative complication occur-rence rate of patients in the observation group was much lower than that in control group （χ2 =4.20,P〈0.05）. Conclusion The application of PVP and PKP can obviously relieve the pain of patients with osteoporotic vertebral compression fractures ,but PKP treatment is more favorable for the recovery of vertebral height and Cobb ＆#39;s angle with little negative effect and high security .
