Two-dimensional finite element analysis was used to obtain the magnitude and distribution of the stresses in models of two different designs of a flexible one-piece double-stemmed first metatarsophalangeal joint implant. The loading and constraint conditions have been reported by previous researchers to occur in vivo at the joint during the push-off phase of the normal walking cycle. Based on the results obtained, the authors recommend the direction that future studies in this area should take.
采用二维有限元分析方法，获取了一种柔性一体式双柄第一跖趾关节植入物两种不同设计模型中的应力大小和分布情况。先前的研究人员已报道了在正常步行周期的蹬离阶段，该关节在体内出现的载荷和约束条件。基于所获得的结果，作者推荐了该领域未来研究应采取的方向。
