摘　　要：目的 :评价脊柱后路手术对胸腰椎骨折受侵犯椎管的复位与重建作用。方法 :对急性胸腰椎骨折或脱位患者86例早期行后路减压复位椎弓根钉棒系统内固定。结果 :术前椎管狭窄率 (42 6±4 7) % ,Cobb角 (17 8±2 8)°,术后分别降低到 (14 5±1 9) %和 (7 8±1 2)°。术前椎体前高为 (38±2 1) % ,术后提高到 (93±10 6) % ,两者比较有显著性差异P<0.001。75例神经功能改善 ,11例无改善 ,有效率87 2 %。结论 :胸腰椎骨折或脱位早期行后路手术椎弓根钉棒系统固定 ,具有矫正后凸畸形疗效满意 ,椎管重建效果可靠 ,截瘫恢复率高等优点 ,是较好的手术方法之一。Objective:To evaluate the reduction of spinal canal encroachment and subsequent remodeling by posterior operation in early stage of spinal trauma.Methods:Eighty_six patients with acute fracture of thoraˉcolumbar or interspinal dislocation were treated.The patients were treated by posterior pedicle instrument.Reˉsults:The straitness changed from(42.6±4.7)%preoperatively to(14.5±2.8)%postoperatively.The Cobb's angle changed from(17.8±2.8)°preoperatively to(7.8±1.2)°postoperat,vely the preoperative height of verteˉbral body was(38±2.1)%,and the postoperative height was(93±10.3)%.There was a significant difference(P<0.001).Neurological function in75patients was improved,and11patients remained stable.The effective rate was87.2%.Conclusion:Effective decompression and remodeling of the canal deformed in patients with aˉcute spine and spinal cord injury can be achieved by posterior pedicle instrument,and neurological function can be improved.
