摘　　要：背景:既往因计算机技术的限制对骨骼生物力学的研究以及骨固定强度、稳定性、疲劳损伤、寿命的预测比较困难。目的:探讨有限元分析法在临床骨科应用的新进展。方法:由第一作者检索至2015年11月为止PubM ed数据(http://www.ncbi.nlm.nih.gov/Pub Med)及CNKI中国期刊全文数据库(http://www.cnki.net/),以"Finite element analysis,Orthopedics,Biomechanics"为英文检索词,"有限元分析,骨科,生物力学"为中文检索词,检索摘要内同时包含上述检索词的文献,总计英文文献51篇,中文文献320篇,根据纳入标准选择其中的40篇进行综述。结果与结论:由于人体骨骼生物力学非常复杂,多数的力学状态是一个运动的、非静态的过程,从而加大了骨科生物力学研究的难度。其中对于骨固定的强度、稳定性、疲劳损伤及寿命的预测也比较困难,而在工程领域中被大量应用和实际论证其可靠性的有限元分析技术能有效的解决这些问题。随着计算机技术的飞速发展,有限元分析在骨科领域应用也越来越广泛,这也促进了骨科技术的发展。BACKGROUND： The limitations of computer technology in the study of bone biomechanics and the prediction of bone fixation strength, stability, fatigue damage and life expectancy are more difficult. OBJECTIVE： To investigate the new progress and application of finite element analysis in orthopedics. METHODS： The first author searched PubMed （http：//www.ncbi.nlm.nih.gov/PubMed） and CNKI China journal full-text database （http：llwww.cnki.netl） published till November 2015. Key words were ＂finite element analysis, orthopedics, biomechanics＂. There were 51 references in English and 320 Chinese literatures. According to the inclusion criteria, 40 literatures were selected. RESULTS AND CONCLUSION： Biomechanics of human skeleton is very complex, and most of the mechanical state is a locomotive, non-static process, thus increasing the difficulty of orthopedic biomechanics research. The prediction concerning bone fixation strength, stability, fatigue damage and lifetime is more difficult. However, the finite element analysis technology, which has been widely applied and demonstrated its reliability actually in engineering fields, can solve these problems effectively. With the rapid development of computer technology, finite element analysis in the field of orthopedic applications has increasingly been used, which also promoted the development of orthopedic technology
