The femur is one of the most highly loaded bones of the human body and its fracture is a devastating event, especially for the elderly people that the surgery is so difficult for them and athletes that it may occurs after substantial trauma. The one-year mortality after hip/femur fracture is about twenty percent and twenty percent of those living in the community at the time of their femur fracture have to be admitted to a nursing home. In this study have been used the three dimensional finite element model of the human femur that it had been constructed by means of the reverse engineering method and unlike many previous works, in this issue had been used full model instead of partial or half model and this three dimensional finite element model has been analyzed under single, expanded and partial expanded loads. The material is assumed to have isotropic elastic characteristics. The results indicated, there are two region for the maximum stresses and this kind of finite element model and its simplification has been verified with the published experimental results and this study has shown that the real produced stress-strain distribution at the human femur when a person was in the single-leg stance phase of normal running or jumping for the first time.
