摘要:

文题释义:
有限元分析:是利用数学方法将连续物体划分为有限个单元,根据单元间节点数目以及实际承受的节点载荷,对每一单元假定一个适宜的近似结果,最后推导出域总的满足条件,得出最终解的一种现代研究方法。

背景:有限元分析作为一种新兴的数字化研究方法,在骨科应用愈加普遍,与骨科联系愈加密切。通过建立有限元三维模型应用于骨科生物力学分析及医疗器械研究设计等具有不可替代的作用。
目的:综述有限元分析在骨科领域的发展前景,为推动有限元分析方法与骨科临床实践更好地结合提供依据。
方法:通过计算机检索万方医学网、中国知网(CNKI)、PubMed、Embase数据库中2012-2021年发表的相关文献,中文检索词为“有限元分析”“生物力学”“脊柱”“关节”“创伤”“骨病”“医疗器械”“综述”,英文检索词为“finite element analysis”“biomechanics”“spine”“joint”“trauma”“osteopathia”“medical instrument”“review”。根据纳入标准,最终纳入47篇相关文献进行归纳总结。
结果与结论:有限元分析方法可对骨关节和相关软组织损伤时的应力状态进行准确模拟分析,在辅助骨科各临床科室查明发病机制、确定治疗方案中发挥积极作用,并能通过将人体骨骼肌肉系统分解为若干个数字化模型进行生物力学分析,指导医疗器械的研发设计,极大地促进了临床诊疗技术的发展,具有良好的发展潜力。但目前有限元分析还存在着方法使用不当、有限元模型建立不准确 、弹性模量标准等问题,还需进一步发展完善,使有限元分析方法更好地满足临床和科研需要。

Abstract: BACKGROUND: As a new digital research method, finite element analysis is more and more popular in orthopedics, and it is more closely related to orthopedics. Through the establishment of finite element three-dimensional model, it has an irreplaceable role in orthopedic biomechanical analysis and medical device research and design. 
OBJECTIVE: To review the development prospects of finite element analysis in the field of orthopedics, and provide a basis for promoting better integration of finite element method with orthopedic clinical practice.  
METHODS: Computer search of relevant documents published from 2012 to 2021 was conducted in Wanfang Medical Network, CNKI, PubMed, and Embase. Chinese and English search terms were “finite element analysis”, “biomechanics”, “spine”, “joint”, “trauma”, “osteopathia”, “medical instrument”, “review”. According to the inclusion criteria, 47 relevant documents were finally included for summary. 
RESULTS AND CONCLUSION: Finite element analysis can accurately simulate and analyze the stress state of bones, joints and related soft tissues. It can play an active role in assisting various clinical departments in orthopedics to identify the pathogenesis and determine the treatment plan. The system is decomposed into several digital models for biomechanical analysis, guiding the research and development and design of medical devices, which greatly promotes the development of clinical diagnosis and treatment technology, and has good development potential. However, in the current use of finite element analysis, there are still problems such as improper use of methods, inaccurate finite element model establishment, and elastic modulus standards. Further development and improvement are needed to make finite element method better meet the needs of clinical and scientific research. 

Key words: finite element analysis, biomechanics, spine surgery, joint surgery, trauma and orthopedics, orthopedics, medical device, review
