[摘要] 目的 探讨AF内固定系统在胸腰椎骨折合并脊髓损伤中的应用。方法 对73例经影像学诊断的胸腰段骨折患者，给予AF系统固定或同时行椎板减压、植骨配合。结果 术后随访7～36个月，平均随访17个月。术后伤椎高度和Cobb角均有满意的恢复，Cobb角由术前的平均28.5°(11.5°～42°)，矫正到术后约4.5°(0°～11.5°)。骨折椎体高度完全恢复者33例，28例>90%，12例>80%。术后CT复查椎管容积明显扩大。神经功能按Frankel分级有1～3级改善。结论 AF内固定治疗胸腰段脊柱骨折合并脊髓损伤，操作简单、固定牢靠、疗效优良。

    [Abstract] Objective To investigation the outcome of thoracolumbar vertebrae fracture combined with spinal cord injury which was treated with atlas fixation (AF) system.Methods Seventy-three patients with thoracolumbar vertebrae fractures combined with spinal cord injury were operated with AF system,some of them were given leminectomy and fusion operation.All patients were followed up for 7~36 months (average 17 months) to observe the treating result.Results According to the X-ray checking,of 33 cases were complete recovery,of 28 cases were >90% and >80% in 12 cases respectively.The affected vertebra height and Cobb’s angle were restored satisfactorily,the Cobb’s angle was revised from avera ged 28.5° (11.5°～42°) preoperatively to averaged 4.5° (0~11.5°) postoperatively.CT result showed that the volumes of the spinal canals were enlarged evidently.Conclusion AF internal fixation for thoracolumbar vertebrae fracture combined with spinal cord injury requires simple manipulation and can provide rigid fixation and satisfactory effect. ......
