目的比较单纯 PKP 与体位复位联合 PKP 治疗老年骨质疏松性椎体压缩骨折的疗效。方法选取我院收治的78例（椎）骨质疏松性胸腰椎椎体压缩骨折，按照随机数字表法分为观察组和对照组，对照 组单纯采用 PKP，观察组采用体位复位联合 PKP。比较两组手术时间、骨水泥用量、术后疼痛缓解情况、术后椎体恢复高度、Cobb 角、骨水泥分布及骨渗漏情况。结果两组手术时间、骨水泥用量、术后骨渗漏情况差异无统计学意义（P ＞0.05）；两组术后3 d VAS 评分、椎体前缘高度、Cobb 角与术前比较，差异均有统计学意义（P ＜0.05）；观察组与对照组比较，术后3d VAS 评分降低，术后3 d、术后3个月椎体前缘高度增加，Cobb 角降低，差异均有统计学意义（P ＜0.05）。 结论 PKP 术前行体位复位可加有效的恢复椎体高度、纠正脊柱后凸畸形及改善术后疼痛，且不增加骨水泥泄露的发生率。%Objective To compare the effects of PKP combined with postural reduction and PKP treated on senile osteoporotic compression fractures. Methods 78 senile osteoporotic compression fractures were divided into observation group treated with PKP combined with postural reduction and control group treated with PKP. The time of surgery, the amount of bone cement, the pain relief effect, the centrum restores highly, the Cobb's angle, the distribution of bone cement and the condition of cement leakage were compared. Results The differences of time of surgery, amount of bone cement and the condition of cement leakage in two group were no statistical significance(P>0.05). The differences of the score of 3d VAS, the height of vertebral anterior edge and the Cobb's angle in two groups were statistical significance before and after operation(P<0.05). After operation, the score of 3d VAS in observation group were lower than control group's. 3 days and 3 months after operation, the centrum restores highly in observation group increased more than control group's. The Cobb's angle in observation group decreased more than control group's. The differences were statistical significance (P<0.05). Conclusion The treatment of PKP combined with postural reduction could improve the centrum restores highly, change the kyphosis and alleviating pain after surgery but it could not increase the occurrence rate of cement leakage.
