摘要：[目的]探讨应用AF系统后柱加压法治疗脊柱后突角过大等特殊情况下非Chance骨折的可行性。[方法]对86例非Chance骨折常规置入椎弓根螺钉后，安装并旋转正反螺纹套筒，使后柱加压，促使骨折复位，复位后安装螺帽及横连杆。[结果]术后伤椎前缘高度恢复至(9921±714)%，Cobb's角恢复至(-503±639)°，与术前相比，均有显著差异(P<001及P<005)；爆裂性骨折椎体后缘高度恢复至(9919±073)%，均较术前有所恢复，但统计分析无明显差别(P>005)。[结论]应用AF系统后柱加压法是治疗特殊情况下非Chance骨折的有效方法，治疗效果满意，对一般的骨折脱位同样适用。关键词： 胸腰椎骨折；AF；内固定

Abstract：[Objective]To investigate the feasibility of posterior column compression technique with Atlas Fixator system (AF) for treatment of nonChance factures of special cases like overlarger kyphosis angle.[Method]A total of 86 cases of nonChance fractures were instrumented with pedicel screw system generally. The positive and negative threaded sleeve were installed and circumrotated to obtain the compressed posterior column and reduction, then the screw cap was installed.[Result]The anterior edge height of the fractured vertebrae was restored to (99.21 ± 7.14)% postoperatively, there was a significant difference ( P < 0.01 ) compared with the preoperative radiographic evaluation. For the collapsed fractures, the posterior edge height of the vertebrae body was restored to (99.19 ± 0. 73 ) %, demonstrating improvement compared with preoperative instance, but was not significant statistically ( P > 0.05 ). The Cobb' angle was restored to (-5.03 ± 6.39 ) degrees, which also had a significant difference compared with preoperative evaluation.[Conclusion]The posterior column compression technique with AF system is applicable for treatment of nonChance fractures in special cases, it's also available for common vertebrae fracture or dislocation and could obtain satisfying prognosis. ......
