摘要
[目的]探讨经伤椎椎弓根螺钉短节段固定技术对亚急性期胸腰椎骨折的复位和固定效果。[方法]对本院2009年4月~2012年3月,27例亚急性(14d^21 d,平均17.9 d)胸腰段单节段骨折采用后路伤椎置钉短节段固定技术治疗,比较术前、术后3 d,术后3、12个月伤椎前缘高度比(FVHR)、矢状面Cobb角矫正情况,以及术前,术后3、12个月Oswestry功能障碍指数(Oswestry disability index,ODI)、疼痛视觉模拟评分(visual analogue scale,VAS)改善情况,并观察内固定有无松动断裂。[结果]27例均获得随访,随访时间12个月。FVHR术前(41.2±15.6)%,术后3 d(90.3±4.8)%,3个月(87.4±4.1)%,12个月(87.1±5.9)%;矢状面Cobb角术前(30.1±7.7)°,术后3 d(5.2±3.2)°,3个月(5.1±2.9)°,12个月(7.4±5.5)°;功能障碍指数(ODI)术前(53.2±9.7)%,术后3个月(24±7.7)%,12个月(10.5±5.4)%;VAS评分术前(5.4±0.9)分,术后3个月(2.1±0.7)分,12个月(1.6±0.8)分;无内固定松动及断裂。[结论]经后路伤椎椎弓根螺钉短节段固定治疗亚急性胸腰椎骨折可达到有效复位、良好固定的效果,是治疗亚急性胸腰椎骨折的有效方法。
[Objective]To investigate the reduction and fixation effect of the injured vertebra transpedicular short-segment fixation technique in the treatment of subacute thoracolumbar fractures.[Method]From April 2009 to March 2012,27 patients with subacute（14 d to 21 d,average,17.9 d） thoracolumbar single segmental fracture were treated by employing the injured vertebra transpedicular short-segment fixation technique,observation were conducted to investigate the anterior vertebral height ratio（FVHR） and Cobb angle within 3 days,3 months and 12 months after the operation,improved result in Oswestry disability index（ODI）,visual analogue scale（VAS） 3 months and 12 months after the operation,and whether the internal fixation was loosen or broken.[Result]All 27 patients were successfully followed up for an average time of 23.2 months（range,12 to 48 months）,with preoperative FVHR of（41.2 ± 15.6） %,and（90.3 ± 4.8） %,（87.4 ± 4.1） %,（87.1 ± 5.9） % within 3 days,3 months and 12 months respectively.The average preoperative Cobb angle were 30.1° ± 7.7°,and 5.2° ± 3.2°,5.1° ± 2.9°,7.4° ± 5.5° within 3 days,3 months and 12 months respectively.The average ODI was（53.2 ± 9.7） % before operation and（24 ± 7.7） %,（10.5 ± 5.4） % at 3 months and 12 months after operation respectively.The average VAS score was 5.4 ± 0.9 before operation and 2.1 ± 0.7,1.6 ± 0.8 at 3 months and 12 months after operation respectively.Looseness or breakage of internal fixation were observed.[Conclusion]The injured vertebra transpedicular short-segment fixation technique,which has been proved to be effective,could optimize reduction and fixation result in the treatment of subacute thoracolumbar fractures.
