摘　　要：根据足三维有限元模型探究跖骨在不同角度内翻状态下力学状态变化。研究结果显示内翻态峰值应力集中于第五跖骨基底,体现了落地时前掌跖骨应力分布。该模型大致反映了足部结构在非正常落地时前掌支撑力学功能,并为损伤原理提供一定指导。The article tries to explore the mechanical changes of metatarsals at different inversion landings based on three-dimensional finite element model of foot. The result shows that the peak stress concentration centers on the proximal part of the fifth metatarsal during inversion landing. This shows the metatarsal stress distribution on landing. The model more or less reflects the forefoot metatarsal support functions during abnormal landing and provides assistance for injury diagnosis.
