目的：评价胸腰爆裂骨折短节段固定附加伤椎置钉内固定并椎体内植骨不融合临床疗效。方法2011年1月-2013年8月选择51例胸腰椎爆裂骨折患者给予附加伤椎固定的三椎体固定，并经伤椎椎体内植骨，不融合进行临床研究。结果51例随诊3~26个月，平均18个月，椎体高度和后凸角无明显丟失，无内固定松动、断裂。术后CT片显示椎管狭窄得到明显改善。脊髓损伤恢复程度，按Frankel分级标准评定，平均改善2~3级。结论胸腰椎爆裂骨折行伤椎固定使术后脊柱稳定性増加，有利于矫正后凸畸形，保留了胸腰椎运动节段，可有效防止创伤后椎间盘退变的发生，有利于脊髄功能恢复。“,”Objective To evaluate the clinical effect of the Short-segment pedicle screw fixation with bone grafting and non-fusion in treatment of thoracolumbar burst fractures. Method 51 patients with thoracolumbar burst fractures between January 2011 and August 2013 included for treatment by hort-segment pedicle screw fixation with bone grafting and non-fusion of fractured vertebra. Result The 51 patients were followed up for 3~26 months (mean 18 months). The vertebral height and kyphosis angle in all patients showed no significant loss; There was no no loosening of fixations or breakage of screws and rods. Postoperative CT scan demonstrated further improvement of the spinal canal narrowing, there was an average improvement of 2-3 grade in the degree of recovery of spinal cord injury according to Frankel assessment criteria. Conclusion Adopting of the injured vertebra fixation for thoracolumbar burst fractures can increase postoperative spinal stability, facilitate kyphosis correction, retain the thoracic and lumbar motion segment, which can effectively prevent the occurrence of traumatic disc degeneration and help restoration of spinal cord function.
