应用Fabric pod行椎体后凸成形术治疗骨质疏松性椎体骨折

目的:评估应用fabric pod行椎体后凸成形术治疗骨质疏松性椎体骨折的临床效果。方法:2007年12月～2010年4月应用fabric pod行椎体后凸成形术治疗骨质疏松性椎体骨折患者13例共15个椎体,男2例,女11例;年龄56～81岁,平均72.2岁;T9 1例,T11 2例,T12 5例,L1 5例,L2 2例;椎体后壁骨折2个椎体,其余椎体后壁完整。均无脊髓和神经受损的症状和体征,疼痛节段椎体MRI脂肪抑制序列均为高信号,VAS评分为8.9±1.4分,Oswestry功能障碍指数(ODI)为(86.1±9.7)%,伤椎椎体前缘高度为14.50±1.34mm,伤椎后凸Cobb角度为28.50°±1.85°。随访观察患者的VAS评分、ODI及影像学改变情况。结果:患者均安全耐受手术,手术时间每节段36～58min,平均45min。未出现骨水泥渗漏,无感染、血管栓塞、脊髓或神经损伤等并发症。术后患者疼痛均明显缓解,术后24h VAS为2.1±1.3分,ODI为(30.5±7.6)%,伤椎椎体前缘高度为23.20±1.12mm,伤椎后凸Cobb角度为11.30±1.40°,与术前比较均有差异性差异(P<0.05)。随访6~22个月,平均12个月,末次随访时VAS为2.2±1.5分,ODI为(32.7±8.4)%,伤椎椎体前缘高度为22.82±0.85mm,伤椎后凸Cobb角度为12.48°±0.70°,与术前比较均有显著性差异(P<0.05),与术后24h比较均无显著性差异(P>0.05)。结论:应用fabric pod行椎体后凸成形术治疗骨质疏松性椎体骨折可显著缓解疼痛、有效恢复骨折椎体的高度,避免骨水泥渗漏,近期疗效满意。

Fabric pod kyphoplasty for osteoporotic vertebral fractures

Objective:To evaluate the clinical and radiographical outcomes of fabric pod kyhoplasty for osteoporotic vertebral fractures(OVFs).Method:13 patients(11 females and 2 males) who sustained OVFs underwent fabric pod kyphoplasty between December 2007 and April 2010.The mean age was 72.2 years old(range,56-81 years).A total of 15 painful OVFs(1 T9,2 T11,5 T12,5 L1,2 L2) were enrolled in our study.Except ford 2 patients,all patients had an intact posterior vertebral wall,and MRI showed marrow edema on fat-satura...
