Finite element analysis applied in the biomechanical study of hallux valgus:reliability and room for improvement / 中国组织工程研究

ABSTRACT

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.
