摘要
目的探讨胸腰段脊柱骨折伴脊髓损伤AF钉治疗效果。方法早期（伤后24小时之内）采用AF钉经椎弓根内固定。术中复位，术中行后外侧大量植骨。治疗结果后凸畸形角由术前31．6°矫正到术后5.2°，矢状面水平位移由术前32.6°纠正到术后10％-12％，压缩椎体高度由术前的48．6％恢复到术后94．2％，不完全瘫痪术后神经功能有Frankel一级以上改善的为91．6％。临床疗效表明AF钉是胸腰段脊柱损伤可选择的良好内固定之一。
Objective： To explore the outcome for the cases of thoracolumbar fracture and spinal cord injury treated with AF internal fixation. Method： At the early stage just 24 hours after the injury, the patients were all performed AF transpedicular internal fixation , with reduction and posterolateral fusion intra-operatively. Result： Compared the parameters before and after the surgery, local kyphosis angle vas corrected from 31.6° to 5.2°, sagittal transverse displacement was from 31.6° to 10%-20%, and compressed vertebrae height was from 48. 6% to 94. 2%. In the incomplete paralysis cases, those with at least one Frankel grade improvement in nerve function occupied 91.6%. Conclusion： Clinical outcome indicates that AF internal fixation is one of the best choices to treat thoracolumbar fracture combined with cord lesion.
