文题释义:
足部结构:足部结构可以影响神经肌肉控制,包括姿势稳定性和体位。足部结构和功能的改变会导致骨骼肌疾病的发生,因此有关足部应力和生物力学方面的研究对足部疾病的损伤病因研究、预防和治疗有重要作用。
有限元模型:基于影像学技术和计算机的有限元分析模型对研究应力分布和疾病相关影响因素起重要作用。利用计算机处理三维图像的功能,模拟在不同功能位置下的骨骼,清楚的显示出复杂的骨骼形状和生物力学的特点。足部有限元模型的建立对足踝部疾病的病因机制、病理及治疗的临床研究具有重要的意义。
摘要
背景:
有限元分析克服传统标本力学分析的不利因素,用于研究足部的生物力学研究有独特的优势,是对足部损伤、病理及治疗的临床研究的重要基础。
目的:回顾现有的一些具有代表性的足部有限元模型,就构建具有生物力学特性足部有限元模型的方法做一综述。
方法:以“有限元模型,生物力学,足结构”为检索词,检索1999至2015年CNKI数据库、万方数据库、PubMed数据库。根据相关资料的阅读和学习,总结国内外学者建立足部有限元模型的方法,包括足部建模数据的获取、实体模型的建立、模型材料属性的设定方法等;总结了足部有限元分析法在运动生物力学以及医疗辅具中的应用现状,指出了有限元法在足部生物力学中应用的特点、不足、模型重建中现有模型不完善的地方及需深入研究的问题。
结果与结论:①目前对足部生物力学的研究己经取了不少研究成果和发现,足部有限元模型为足部的生物力学分析、损伤模拟等研究提供了一数字平台;②有限元模型建立过程中,从医学图像到直接可用于有限元分析的数值模型必须同时借助多种关键技术来实现,包括自适应的图像分割方法、六面体网格生成方法和多材质有限元建模等;③不同的约束条件、图像采集精确度,有限元计算的结果等可能会影响建模的结果,需要通过不同技术和验证方法的不断改进来增加有限元模型的可靠性。

Abstract:

BACKGROUND: The finite element analysis used to study the biomechanical properties of foot structure contributes to overcome the disadvantages of traditional mechanical analysis of specimens.
OBJECTIVE: To summarize some representative finite element models of the foot and review the establishment methods of finite element models of the foot with biomechanical properties.
METHODS: A computer-based online search was conducted in CNKI, Wanfang and PubMed databases by using the key words of “finite element model, biomechanic, foot structure” from 1999 to 2015. The language was limited to both Chinese and English. Establishment methods of finite element models of the foot structure containing obtaining of model establishment data, establishment of solid model, setting methods of properties of model materials. The application of finite element analysis of the foot structure in sports biomechanics and medical orthotics was summarized to point the characteristics and disadvantages of finite element analysis application in biomechanics.
RESULTS AND CONCLUSION: An increasing number of studies on foot biomechanics provide the platform for finite element analysis of the foot applied in biomechanical analysis. Many key technologies, including self-adaption image segmentation method, hexahedron grid product method and establishment of finite element models with various materials have to be utilized to converse the medical images into digital models of finite element analysis during establishment of finite element models. Results of model establishment may be affected by limitation conditions, accuracy of image collection, calculation results of finite element analysis. The reliability of finite element models can be increased by modify technologies and verification methods.
