摘要
背景:关于椎弓根螺钉植入定位导向技术的研究成为影响置钉成功率的重要因素。目的:探讨腰椎椎弓根螺钉进钉点的技巧及在基层普及腰椎骨折椎弓根固定的可行性。方法:第一作者应用计算机检索PubMed数据库及CNKI数据库,探讨不同方法治疗腰椎椎弓根螺钉进钉点的个体化定位在临床应用的安全性和远期疗效。纳入与腰椎椎弓根钉螺进钉点相关的文章,以24篇文献为主重点进行了讨论。结果与结论:椎弓根螺钉植入3步为定位、定向、定深。定位有Roy-Camille法、Weinstein法、Mager法和Louis法。定向分矢状面角和水平面角。定深临床实践表明椎弓根螺钉占据椎体的80%时较为适宜。以椎板边缘对腰椎椎弓根螺钉进钉点个体化定位方法是可行和可靠的、创伤小、准确率高。
BACKGROUND：Implanted positioning of pedicle screws is an important factor for successful pedicle screw implantation.OBJECTIVE：To investigate the technique of implanting pedicle screws and the feasibility of popularizing the application of pedicle screw fixation.METHODS：The first author searched PubMed database and CNKI database for articles regarding clinical safety and long-term effect of different methods for entrance point location of pedicle screw implantation.Finally,24 articles were included in result analysis.RESULTS AND CONCLUSION：There are three steps for pedicle screw implantation：positioning,orientation,and depth setting.Roy-Camille method,Weinstein method,Mager method and Louis method are used for pedicle screw positioning.Orientation of pedicle screws includes sub-horizontal angle and sagittal angle.It has been proved by clinical practice that the pedicle screw occupying 80% of the vertebral body is appropriate.To ensure the individual entrance point positioning of pedicle screw implantation based on the laminar edge is feasible and reliable with small wound and high accuracy.
