| 目的 探讨两节段骨质疏松性椎体压缩性骨折经皮椎体后凸成形术的实施方法，评价手术疗效。方法 对33例两节段椎体压缩性骨折患者的66个伤椎，实施经皮椎体后凸成形术，测量手术前后伤椎的椎体矢状面指数、后凸Cobb角，于术前、术后l周、术后1年，进行模拟视觉类比评分和功能障碍指数评分，评价疼痛缓解情况和脊柱功能恢复情况。结果 所有患者均获得随访，随访时间12-18个月(平均14.3个月)，骨水泥外渗3例4个椎体。术前、术后1周和术后1年，平均椎体矢状面指数分别为0.67±0.33、0.93±0.15和0.91±0.48，术后1周、术后1年与术前比较，有显著性差异(F值=83.62，P<0.01)；后凸Cobb角分别为(36.33±6.83)0、(7.33±6.37)0和(9.18±6.75)0，术后l周、术后1年与术前比较，具有显著性差异(F值=64.41，P<0.01)；模拟视觉类比评分分别为(9.09±0.83)分、(1.72±1.10)分和(1.90±0.94)分，术后1周、术后1年与术前比较，具有显著性差异(F值=207．89，P<0.01)；功能障碍指数评分分别为(81.27±4.12)分、(17.96±3.37)分和(20.41±4.03)分，术后1周、术后1年与术前比较，具有显著性差异(F值=297.23，P<0.01)。结论 经皮椎体后凸成形术治疗两节段骨质疏松性椎体压缩性骨折，伤椎高度恢复、后凸Cobb角的矫正、止痛效果和脊柱功能恢复情况均满意。 |

| Abstract：0bjective To explore and evaluate the surgical efficacy of pereutaneous kyphoplasty(PKP)on the treatment of two segment osteoporotic vertebral compression fractures(OVCFs)．Methods PKP was performed in 33 patients with two segment OVCFs．The vertebral saggital index(VSI)and Cobb,s angle of the fractured vertebrae were measured pre-operatively and post-operatively．Visual analogue scale(VAS)and Oswestry disability index(ODI)were calculated to evaluate the release of pain and the recovery of spinal function pre-operatively and on 1 week and 1 year postoperatively．Results All patients were followed-up for an average of 14.3 months(from 12 to 18 months)．Leakage of bone cement was found in 4 vertebrae of 3 patients．VSl was 0.67±0.33 pre-operatively，0.93±0.15 one week post-operatively，and 0.91±0.48 one year post-operatively，respectively．VSI in pre-operative group was significantly different compared to that in 1 week post-operative group and in 1 year post-operative group(F=83.62，P<0.01)．The Cobb,s angle was 36.33±6.83 degree pre-operatively，7.33±6.37 degree 1 week post-operatively，and 9.18±6.75 degree 1 year post-operatively，respectively．The Cobb,s angle in pre-operative group was significantly different compared to that in 1 week post-operative group and in 1 year post-operative group(F=64.41，P<0.01)．The VAS score was 9.09±0.83 pre-operatively，1.72±1.10 one week post-operatively，and 1.90±0.94 one year post-operatively。respectively．The VAS score in pre-operative group was significantly different compared to that in 1 week post-operative group and in 1 year post-operative group(F=207.89。P<0.01)．The ODI score was 81.27±4.12 preVoperatively，17.96±3.37 one week post-operatively。And 20.41士4.03 one year post-operatively．respectively．The ODI score in pre-operative group was significantly different compared to that in 1 week post-operative group an 1 year post-operative group(F=297.23，P<0．01)．Conclusion It is satisfied using PKP for the treatment of two-segment OVCFs，in terms of Teeovery of vertebral height，rehabilitation of Cobb,s angle，relief of the pain，and restoration of spinal function． |
