摘要
目的分析和评估轴形内固定(AF)的临床应用价值。方法对42例胸腰椎骨折患者行AF内固定。每位患者术前均行X线、CT等影像学检查。术中按Megerl法置钉常规摄定位X线片。42例中39例获得随访,平均21个月,观察内固定及神经症状恢复情况。结果术后Cobbs角平均改善23.2°,压缩椎体高度均恢复40.2%,14例合并神经系统症状患者,12例有明显改进(2例FrankelA级无明显改善)。结论AF钉具有创伤小、出血少、操作相对简单安全、固定节段少等优点,特别适用于胸腰椎骨折脱位后路减压和复位需要重建脊柱稳定性的治疗。
Objective To evaluate the clinical efficacy of AF (atlas fixator) internal fixation in treatment of thoracolumbar fracture and dislocation. Methods 42 cases of thoracolumbar fracture were treated by posterior AF internal fixation. Prior to surgery, anteroposterior and lateral radiographs, and CT scan through bone windows were done for all the patients. During surgery, all the pedicle screws were inserted by Mergerls method and proper insertion was confirmed by radiographs. Results The follow ups of 39 patients averaged 21 months (ranging from 6 to 29 months). After surgery, the correction of anterior vertebral body height averaged 40.2%, and of Cobbs angle 23.2°. 12 cases of incomplete spinal cord injury had significant improvement and 2 ones of complete spinal cord injury had no improvement. Conclusion The AF screw is especially helpful in reconstruction of stability of thoracolumbar region after posterior decompression and reduction, because it results in simplicity, safety, less fixation segments, and little invasion or bleeding.
