摘　　要：目的　总结ＳＦ内固定器治疗胸腰椎骨折及滑脱的临床疗效。方法　应用ＳＦ钢棒治疗胸腰椎骨折及滑脱１８ 例，根据正位Ｘ 线椎弓根投影确定进钉点，根据骨折及滑脱部位选择合适的钢棒。如为滑脱，则应用提拉螺钉复位，保持螺钉尾部钢槽与连接杆纵轴一致。比较术前术后椎体高度和椎间隙宽度变化。结果　平均随访１０ 个月，脱位及压缩畸形复位率达９０％ 以上，不全瘫１２ 例全部恢复，全瘫１ 例部分恢复。结论　ＳＦ由于内固定器连接杆设计成弧形而形成类似脊柱前凸的钉杆角，从而保证了钢棒与椎板紧贴，防止了因钢棒与椎板间剪力所致螺钉断裂。手术操作简便，复位效果满意。Objective\ To conclude the curative effect of SF rod on spinal fractures and spondylolisthesis. Methods\ 18 cases of thoraco lumbar fractures and spondylolisthesis were treated with SF internal fixations. The entrance point was determined according to the vertebral arch position in X ray. The spondylolisthesis was corrected by using elevating screw. 3 screw nails were kept in a straight line. The altitude and width of spinal fracture were compared during treatment. Results\ The average follow up time was 10 months, and the reduction rate was over 90% by using internal fixation. 12 cases of paraplegia were completely recovered and 1 case of complete paraplegia was recovered partly. Conclusion\ As connecting rod is designed with arc, the screw rod angle becomes just like spinal curve, it ensures the close neighbour of steel rod and spine and prevents the screw broken, the operation is much simpler than procedure of Dick system. A statisfactory effect of reduction has been obtained by using SF internal fixation.
