后路复位椎弓根螺钉固定治疗严重胸椎骨折脱位的临床疗效

目的:探讨后路复位椎弓根螺钉治疗严重胸腰椎骨折脱位的临床疗效。方法:应用钉棒系统椎弓根螺钉复位内固定治疗严重胸腰椎骨折脱位18例,全部采用后入路手术,术中视情况决定椎管减压、椎间融合或后外侧融合。结果:全部病例经过6个月～4年随访,椎体前缘高度由术前平均34%恢复至术后90%,后缘平均高度由术前的54%恢复到术后的96%。cobb角由术前平均29°恢复至术后7°,合并脊髓损伤ASIA分级神经功能评分均升高一级,椎间植骨或外侧植骨均融合,无断钉、断棒、螺钉松动及感染发生。结论:后路复位椎弓根螺钉治疗严重胸腰椎骨折脱位具有骨折复位满意、固定牢靠,操作简单等优点,是治疗严重胸腰椎骨折脱位的一种可靠方法。

The clinical efficacy of severe Thoracic and lumbar fracture and dislocation with Posterior reduction and pedicle screw Long phase fixation

Objective：To study clinical efficacy Of severe thoracolumbar fracture and dislocation with posterior reduction and treatment of pedicle screw Long phase fixation.Methods： Application of screw Long phase fixation for severe thoracolumbar fracture-dislocation in 68 cases by posterior approach used in all surgical,as appropriate Spinal surgery decision：interbody fusion or posterolateral fusion.Results：All patients after 6 months to 4 years follow-up,Anterior vertebral height of an average of 34% from preoperative to postoperative recovery 90%,the average height of posterior 54% from postoperative recovery of 96%.cobb angle from average of 29 ° to resume 7 °.Spinal cord injury ASIA neurological grading were higher level,Interbody fusion or lateral bone graft shows no broken nails,no broken stick,no screw loosening,and no infection.Conclusion：Posterior pedicle screw long phase fixation with treatment of severe thoracolumbar fracture dislocation is satisfactory and reliable method for dislocation
