骨水泥渗漏对经皮椎体后凸成形术效果的影响

Effects of polymtthyMethacrylate leakage on the efficacy of percutaneous kyphoplasty

目的探讨经皮椎体后凸成形术(PKP)中并发骨水泥渗漏患者的临床效果。方法78例椎体疾病患者的92个病椎,所有患者均于C臂机监视下进行PKP,术后行X线片检查了解骨折椎体复位情况、骨水泥分布情况,根据骨水泥渗漏情况将患者分为渗漏组及非渗漏组,观察并记录两组患者术前、术后3d和1、3个月的疼痛视觉模拟评分(VAS)。结果共有20例22个椎体出现骨水泥不同程度漏出,骨水泥渗漏率为23.91%。所有患者术后VAS均明显低于术前(P<0.01),渗漏组与非渗漏组各时点VAS差异无统计学意义。结论PKP对椎体骨折的镇痛效果明显。少量的骨水泥渗漏发生率较高,并不影响PKP的手术效果。

Objective To investigate the effects of polymtthy methacrylate （PMMA） leakage on the results of percutaneous kyphoplasty （PKP）. Methods PMMA was injected percutaneously in 78 cases （92 vertebraes） . The patients were assigned to leakage group and non[eakage group. VAS was recorded before operation,on the 3rd postoperative day and 1st , 3rd postoperative month. Results PMMA leakage was observed in 22 vertebraes of 20 cases with a leakage rate of 23.91%. VAS scores were lower after operation than those before （P〈0.01）. There was no significant difference in VAS scores between the two groups. Conclusion The PKP produces effective relief of back pain. A small amount of PMMA leakage does not affect the effectiveness of PKP.
