摘要：

背景：椎弓根螺钉内固定经过不断的发展和完善，生物力学理论在脊柱内固定器方面也有了很大进展。
目的：对脊柱椎弓根螺钉应用的生物力学研究进行综述。
方法：应用计算机检索1986-01/2010-10 CNKI和Pubmed数据库，在标题和摘要中以“椎弓根螺钉，生物力学”或“Pedicle Screw，Biomechanics”为检索词进行检索。选择文章内容与椎弓根螺钉的生物力学有关者，同一领域文献则选择近期发表或发表在权威杂志文章。最终入选49篇文献进行综述。
结果与结论：在椎弓根螺钉的发展过程中，生物力学不仅为内固定的研制提供理论基础，也是测试和评价新设计内固定器效果的最终依据和标准。文章结果显示椎弓根螺钉植入点、植入方向、螺钉大小、螺钉形状、螺钉材料对脊柱生物力学均有一定影响。

Abstract:

BACKGROUND: Pedicle screw internal fixation after constant development and perfection has been advanced in spinal fixator field from aspect of biomechanics theory.
OBJECTIVE: To review the biomechanical study of spinal pedicle screws.
METHODS: CNKI and Pubmed (1986-01/2010-10) were retrieved to search the related articles about biomechanics of pedicle screws using the keywords of “pedicle screws, biomechanics” in Chinese and English. Finally 49 articles were included.
RESULTS AND CONCLUSION: In the development process of pedicle screws, biomechanics not only provides theoretical foundation for the development of the internal fixation, but also is the ultimate basis and holder effect standard for testing and evaluation of new designs. Pedicle screw implantation point, implant orientation, screw size, screw shape, screw materials have a certain impact on spinal biomechanics.
