摘要
目的探讨经椎弓根撬拨复位、椎体打压植骨治疗胸腰段爆裂性骨折的临床疗效。方法 2006年2月～2011年2月采取经后路椎弓根螺钉内固定、经伤椎椎弓根撬拨复位、椎体打压植骨方法治疗胸腰段爆裂性骨折29例,其中男性18例,女性11例;年龄19～63岁,平均42岁。对手术前后伤椎前后缘高度比、伤椎楔变角、椎管容积率及脊髓损伤分级进行比较分析。结果术前伤椎前后缘高度比为0.48±0.05,术后为0.92±0.08;术前伤椎楔变角为23.32°±2.60°,术后为2.78°±1.42°;术前椎管容积率(45.10±1.60)%,术后(95.50±4.10)%。差异均具有统计学意义(P<0.01)。结论经椎弓根撬拨复位、椎体打压植骨治疗胸腰段爆裂骨折,有助于恢复椎体高度,重建脊柱稳定性。
Objective To investigate the clinical efficacy of transpedicular bone graft and reduction in treating thoracolumbar burst fractures. Methods Twenty：nine patients with thoracolumbar burst fractures from Feb. 2006 to Feb. 2011 were included in this study. There were 18 males and 11 females,aged from 19 to 63 years （ averaging 42 years）. All of them received transpedicular bone graft and reduction. The ratio of anterior/posterior height of compressed vertebral bodies, kyphotic angle, spinal canal capacity ratio and ASIA grade of neurologic function were evaluated preoperatively and postoperatively. Results The mean ratio of anterior/posterior height of compressed vertebral bodies was 0.48 ± 0.05, which was improved to 0.92 - 0.08 after surgery ; the mean preoperative kyphotie angle was 23.32° ±2.60° and decreased to 2.78° ± 1.42° after surgery; the mean preoperative spinal canal capacity ratio was （ 45.1 ± 1.6 ） %, which was restored to （ 95.5 ± 4.1 ） %. There were significant differences in these indices （ P 〈 0. 01 ）. Conclusion Combination of transpedicular bone graft and reduction is more helpful for patients with thoracolumbar burst fractures in restoring the spinal vertebral height and rebuilding the stability of the spine.
