摘　　要：背景:下颈椎椎弓根螺钉固定能够贯通脊柱前中后三柱,有效恢复颈椎矢状序列、提供坚强内固定和高融合率,是颈椎生物力学上最稳定的内固定。目的:通过查阅国内外相关文献,对下颈椎椎弓根螺钉固定相关的椎弓根解剖结构、置钉固定的生物力学性能、3D打印技术辅助置钉应用等方面进行概括。方法:第一作者应用计算机检索1990年1月至2017年1月Pub Med数据库、中国期刊全文数据库有关下颈椎椎弓根螺钉固定的文章,英文检索词为"lower cervical,pedicle screw,3D printing technology",中文检索词为"下颈椎,椎弓根螺钉,3D打印技术"。总计收集文献193篇,排除重复性研究、个案报道及Meta分析类文章。结果与结论:(1)最终纳入52篇文献进行综合分析;(2)综述结果显示,尽管下颈椎椎弓根螺钉固定有很高的风险,只要进行充分的术前个性化评估和术中精准的置钉技术,可将其风险至最低甚至避免,具有很高的临床应用价值。BACKGROUND： The lower cervical pedicle screw fixation is the most stable internal fixation of the cervical spine in biomechanics, which can penetrate the anterior, middle and posterior columns of the spine, effectively restore the sagittal sequence of the cervical spine, provide strong internal fixation and high fusion rate. OBJECTIVE： To review the relevant information of the anatomical structure of lower cervical pedicle, the biomechanical property of screw fixation, and three-dimensional printing technology-assisted screw placement at home and abroad. METHODS： PubMed and CNKI databases were searched for the articles concerning lower cervical pedicle screw fixation from January 1990 to January 2017. The key words were ＂lower cervical, pedicle screw, 3D printing technology＂ in Chinese and English, respectively. Totally 193 articles were researched, and the repetitive research, case report and meta-analysis were excluded. RESULTS AND CONCLUSION： （1） Finally 52 eligible articles were enrolled for result analysis. （2） Although it has a very high risk to fix lower cervical pedicle screw, the risk could be minimized or avoided through fully individualized evaluation preoperatively and precise fixation intraoperatively. So the lower cervical pedicle screw fixation has high clinical value.
