摘　　要：目的：探讨经后路椎弓根钉棒系统内固定治疗胸腰椎骨折的临床疗效。方法：对本组35例胸腰椎骨折行后路椎弓根钉棒系统内固定,其中20例行术中后路减压,8例经椎弓根行病椎植骨。35例均行关节突及横突间植骨。并测量术前、术后伤椎前后缘平均高度（百分比）和Cobb’s角,椎管截面积。结果：术后伤椎前后缘平均高度（百分比）和Cobb’s角,椎管截面积各项指标与术前相比较,差异有显著性（P〈0.01）。术后随访9-21个月,平均13.2个月。无一例出现神经症状加重,2例出现内固定断裂并完整取出。结论：经后路椎弓根钉棒系统内固定治疗胸腰椎骨折疗效确切,是治疗胸腰椎骨折的一种创伤小,操作简单,固定可靠的手术方法。Objective：To discuss the clinical efficacy of posterior internal fixation of vertebral pedicle screw and bar system for thoracolumbar spine fractures.Methods：Thirty-five cases with thoracolumbar spine fractures were treated by posterior internal fixation of vertebral pedicle screw and bar system,20 cases among them have been done by intra-operative posterior decompression,8 cases by bone grafting.All the 35 cases were treated by bone grafting between zygopophysis and transverse process;meanwhile,measure the average height of fro-and-aft edges of injured spine before and after operation separately, Cobb angle, vertebral section surface. Results： the average height mentioned above, Cobb angle and vertebral section surface had all got distinct improvement. All these eases were followed-up for 9-21 months, 13.2 months in average. They received good results without any neurological symptoms, but 2 cases fixations were fractured and fully taken out. Conclusion： Posterior internal fixation of vertebral pedicle screw and bar system is an efficient method for thoracolurnbar spine fractures, it has many advantages： small trauma, easy to control and stable fixation.
