【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。更多还原

【Abstract】 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 cases 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 thoracolumbar spine fractures,it has many advantages:small trauma,easy to control and stable fixation.更多还原
