以应力传导分析方法确定胸腰椎椎弓根置钉路径的应用研究

Applied research on determination of thoracic and lumbar vertebra pedicle screw placement path by stress conduction analysis method

目的探讨以应力传导分析方法确定胸腰椎椎弓根置钉路径在临床中的应用效果。方法回顾性分析自2018-01—2020-06采用椎弓根钉内固定治疗的520例胸腰椎疾病。269例采用应力传导分析方法确定置钉路径进行置钉(观察组),251例采用传统置钉方法置钉(对照组)。比较两组胸椎、腰椎一次置钉成功率以及总一次置钉成功率。结果两组均顺利完成手术,观察组共置钉1 289枚,对照组共置钉1 218枚。观察组胸椎、腰椎一次置钉成功率以及总一次置钉成功率较对照组高,差异有统计学意义(P<0.05)。结论以应力传导分析方法确定胸腰椎置钉路径的改良方法可以提高置钉准确性,实现个体化椎弓根置钉,有较大的临床应用价值。

ObjectiveTo study the determining method for the thoracic and lumbar vertebra pedicle screw placement path by stress conduction analysis.Methods screw internal fixation from January 2018 to June 2020 was conducted, 269 cases used the stress conduction analysis method to determine the screw placement path for screw placement(observation group) and 251 cases used traditional screw placement methods(control group). The number of successful placements of thoracic and lumbar spine at one time and the total number of successful placements at one time were compared between the two groups.Results completed in two groups, a total of 1 289 screws were placed in the observation group and 1 218 screws were placed in the control group. The success rate of thoracic and lumbar spine fixation at one time and the total number of successful fixation at one time in the observation group were higher than those in the control group, and the difference was statistically significant(P<0.05).ConclusionUsing the novel method of pedicle screw implantation determined by spinal stress can improve the accuracy of pedicle screw implantation with greater clinical application value and the individualized pedicle screw placement can be achieved.
