有限元分析法在拇外翻生物力学研究中的应用:可靠性与提升空间

Finite element analysis applied in the biomechanical study of hallux valgus: reliability and room for improvement

背景:拇外翻是一种病因复杂的临床常见病,其治疗方法多样。其中拇外翻的力学分析是目前研究的重点。应用有限元分析方法对拇外翻进行力学分析使得其治疗变得可以预测。目的:探讨有限元分析法在拇外翻生物力学研究中的临床应用。方法:以中文检索词"有限元,拇外翻"和英文检索词"Finite element,hallux valgus"分别检索1980年1月至2017年3月CNKI数据库和PubMed数据库。排除与文章目的无关、内容重复及低质量文献。根据入选标准保留33篇文献,对有限元分析应用于拇外翻的关键问题进行综述。结果与结论:(1)目前对拇外翻的有限元研究方法很多,大多需要医工合作去完成,方法较成熟,但是国内建立模型材料属性的数据大多是来自国外的研究;(2)有限元分析方法在拇外翻的病因研究、术前规划和预后判断等方面有着重大的实用价值,具有一定的可靠性;(3)拇外翻有限元模型局限在静态分析和步态周期分析方面,同时在建模细节和对材料属性的定义方面也有着很大的提升空间。

BACKGROUND:Hallux valgus is a common orthopedic disease,and its causes are complex and treatment is varied.The mechanical analysis of hallux valgus is an issue of concern.The finite element analysis makes it predictable to treat hallux valgus.OBJECTIVE:To explore the clinical application of finite element analysis in biomechanical study of hallux valgus.METHODS:The first author searched CNKI and PubMed databases from January 1980 to March 2017 using the key words of“finite element,hallux valgus”in English and Chinese,respectively.The repetitive,irrelevant and low-quality articles were excluded.Finally 33 eligible articles were included in accordance with the inclusion criteria,and the critical issues of finite element analysis applied in hallux valgus were reviewed.RESULTS AND CONCLUSION:(1)There are many researches concerning finite element of hallux valgus,which mostly require physicians to work with engineers.These methods are already very mature,but most of the model and material properties of the data come from foreign researches.(2)The finite element analysis is important and reliable for the etiology of hallux valgus,preoperative planning and prognosis.(3)The finite element model of the hallux valgus is only used on static analysis and gait cycle analysis,the modeling details and definition of material properties still need to be improved.
