有限元分析法在腰椎生物力学研究中的应用

Application of finite element analysis in lumbar spine biomechanics

背景:有限元分析法是目前是脊柱生物力学常用研究方法之一,随着成像、图像处理的进步及有限元分析软件的不断开发与应用,脊柱生物力学研究得到了更深入的发展。目的:综述有限元的概念、原理与其他生物力学研究方法的差别。方法:应用计算机检索中国知网数据库、维普数据库和PubMed数据库中1979/2011-01关于腰椎生物力学有限元分析的文章,在标题和摘要中以"腰椎;有限元;生物力学"或"lumbar,finite element,biomechanics"为检索词进行检索。选择文章内容与腰椎有限元分析相关,同一领域文献则选择近期发表或发表在权威杂志文章。共收集591篇文献,根据纳入标准选择20篇文献进行综述。结果与结论:近几年有限元分析法在腰椎生理和病理情况生物力学分析中的应用;不同手术方式、内固定器械及人工植入物对腰椎生物力学的影响均有不同。

BACKGROUND： Finite element analysis is one of the spine biomechanics research methods that can commonly be used now. With the progress of imaging and image processing, the continuous development and application of finite element analysis software, spine biomechanics researches are further developed. OBJECTIVE： To introduce the differences of concept, principle between finite element and the other biomechanical study methods. METHODS： Chinese journal full-text, Chinese science and technology periodical and PubMed databases were retrieved by computer for articles published from January 1979 to January 2011 about the finite element analysis of lumbar spine biomechanics in the title and abstract with the key words of ＂lumbar, finite element, biomechanics＂ in Chinese or ＂lumbar, finite element, biamechanics＂ in English. Articles related to lumbar finite element analysis were selected. The articles which published in recently literatures or the authoritative magazines were selected in the same field. A total of 591 articles were selected, finally 20 articles were involved for summarization according to inclusion criteria. RESULTS AND CONCLUSION： In recent years, application of the finite element analysis in biomechanics analysis of physiological and pathological conditions in lumbar spine： different operative methods, fixation devices and artificial implant on the influence of lumbar biomechanics are different.
