文题释义:
下颈椎:即低位颈椎,指C3-7,因解剖结构和功能相似,故临床上习惯称为下颈椎。下颈椎处于颈椎生理前凸和胸椎后凸交界处的特殊解剖位置,活动度大、应力分布集中,是颈椎损伤最多的部位。长期低头或俯案工作及不良生活习惯均易引起颈椎急慢性损伤,引发颈椎病。
3D打印技术:即快速成型技术的一种,它是一种以数字模型文件为基础,运用粉末状金属或塑料等可黏合材料,通过逐层打印的方式来构造物体,多采用数字技术材料打印机来实现的技术。3D打印技术应用于医学领域可用于制作人体骨骼、牙齿、器官、支具等模型,骨科应用3D打印技术还可以制作辅助螺钉置入的导航模板、辅助截骨的截骨导板。
 
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PubMed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。

Abstract:

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.
