摘要：

背景：有限元分析因其在生物力学研究方面独特的优势，近年来逐渐成为足部疾病病理机制、治疗及矫形支具制作等研究领域的有力的工具。
目的：就足部有限元模型的建模方法应用进展，包括数据的采集方法、材料的特性和参数、建模方法和常用有限元软件做综述。
方法：通过计算机检索中国期刊全文数据库(CNKI)、PubMed数据库、万方数据库及维普数据库1980-01/2009-05期间的相关文章，检索词为“有限元法，有限元模型，足，Finite element method，foot，Finite element model。主要纳入了有关有限元法数据的采集方法研究、足部的材料的特性和参数的研究、建模方法研究等方面论文资料。对方法重复、相关参数未做详细介绍的论文予以剔除。
结果与结论：从CT和MR图像上获得研究对象数据的方法是目前最为广泛使用的方法。在CT三维重建技术与有限元三维重建技术间建立程序接口，使有限元软件可以直接读取CT三维建模，将成为医学有限元建模发展的趋势。目前足部有限元模型的材料特性和参数大多参考国外文献，尚未见国内开展材料参数的测试研究工作的报道。在材料特性方面,适应生物力学研究的非线性和组织各向异性足部模型将成为主流。

Abstract:

BACKGROUND: Finite element analysis is becoming a kind of strong tool in pathologies, treatment and manufacture of orthopedic brace in the research area of foot diseases because of its unique advantage in biomechanical research in recent years.
OBJECTIVE: To review the applied situation of finite element modeling method in foot, consisting of scientific methods of data acquisition, reliable material characteristics and parameter definition, modeling method and the software of finite element.
METHODS: To search the articles from January 1980 to May 2009 by computer in CNKI database, PubMed database, Wanfang database and Vip database. The index words were “finite element method, foot, finite element model”. The articles included the studies on methods of data acquisition, on material characteristics and parameter definition and on modeling method. The articles which to repeat the similar method, not to introduce the relative parameters in detail were deleted.                                   
RESULTS AND CONCLUSION: It was the most popular method in current years to acquire the data of study object from CT and MR images. It will be the developing tendency of medical finite element modeling method to establish program interface between 3-D rebuilt technique of CT and finite element which finite element software can directly read 3-D model of CT. The material characteristics and parameter of foot finite element model mostly referred to the foreign data. The studies of material parameter test were not reported. In the field of material characteristics, the finite element model of foot with nonlinearity and tissue anisotropy will be the main stream.
