【摘要】 目的分析AF系统治疗胸腰段爆裂型骨折术中造影的意义。方法总结应用AF系统对伤椎进行复位及内固定,术中结合椎管造影决定是否直接开放椎管减压的28例病例,从影像学、手术操作过程及神经功能恢复等方面分析疗效。结果伤椎高度从46.1%恢复到正常的94.2%,水平移位完全恢复,Cobb氏角由术前21.6°恢复到术后3.7°。椎管受压程度:删除椎管开放减压的5例病例,受压面积从术前41%恢复到术后16%,受压的矢状径从术前54.7%恢复到80.8%。脊髓神经功能恢复依照Frankel分级标准有1级以上改善。结论AF系统对胸腰段爆裂型骨折治疗效果良好,对其合理选用并结合术中造影可以达到优于其它固定方法的效果。更多还原

【Abstract】 Objective To investigate the effect of the treatment of thoracolumbar burst fracture by AF system and myelography in operation. Methods 28 cases with injured vertebras were treated with AF reduction, internal fixation, and myelography the result of which decided whether the patient needed direct decompression of the spinal canal. The effect of the treatment was analyzed in terms of radiography, operative procedure and functional recovery of the nerve. Results The height of the injured vertebra recovered from 46.1% to 94.2% of the normal. The horizontal displacements completely recovered. The Cobb s angle changed from the preoperative 21.6° to the postoperative 3.7° .Apart from the 5 cases treated by open decompression of the spinal canal, the compressed area recovered from the preoperative 41% to the postoperative 16% . The sagittal diameter of the compression changed from 54.7% to 80.8% . The spinal function improved over one grade, according to Frankel’s classification. Conclusion AF system, if used reasonably and combined with myelography in operation, can treat thoracolumbar burst fracture more effectively than the other ways of fixation.更多还原
