TSRH器械在特发性脊柱侧凸中的应用

目的]观察TSRH三维矫形系统矫正特发性脊柱侧凸冠状面、矢状面和轴状面的疗效,评价应用钉棒系统和钉钩棒系统随访时的效果。方法]分析采用TSRH系统治疗特发性脊柱侧凸79例,男48例,女31例,平均15.5岁。全部应用椎弓根螺钉系统56例,胸椎应用椎弓根钩或椎板钩,腰椎应用椎弓根螺钉23例。对照分析2组的矫正效果。结果]术后冠状位矫正为18~31°,矫正率为56%~87%,平均为68%,矢状位矫正为21~33°,平均25°,旋转矫正Ⅰ度。身高平均增高3 cm。63例平均随访2.5 a,2组冠状面和矢状面的矫正率以及冠状面矫正度的丢失有明显的差异。结论]TSRH矫形系统治疗脊柱侧凸可得到满意的治疗效果,应用椎弓根螺钉效果更佳。

Application of TSRH in idiopathic scoliosis

Objective]To review the therapeutic effect of TSRH in correction of coronal plane,sagittal plane and horizontal plane malformation of the idiopathic scoliosis,and to evaluate the result of screw-rod and screw-crook-rod system.Method]A total of 79 idiopathic scoliosis patients who were corrected with TSRH were analyzed.There were 48 males and 31 females with an average age of 15.5 years.Only pedicle screws system was used in 56 cases,pedicle crook or vertebral plate crook in thoracic vertebra,pedicle screws system in lumbar vertebrae were used in 23 cases,then the results of two groups were compared.Result]Cobb's angel in coronal plane was corrected from 18 to 31 after operation,the correction rate was from 56 percent to 87 percent,with an average of 68 percent;while Cobb's angel in sagittal plane was corrected from 21 to 33 after operation,with an average of 25.Rotation was corrected by I degree,heights were increased by 3 cm in average.The mean followed-up duration of 63 cases was two years and a half year.There was significant difference between the two groups in correction rate in coronal plane and sagittal plane,also in loss of correction in coronal plane.Conclusion]TSRH could make satisfying results in correction of idiopathic scoliosis,and the result would be better if pedicle screws system is used.
