The purpose of this project is to evaluate fracture risk in fall accident of pedestrian and discuss a preventive diagnosis system for hip fracture which is frequently observed among Japanese elderly female. Hip fracture is one of the most important medical problems in Japanese geriatric medicine because it makes a patient difficult to stand and walk. In this study, we constructed a multibody Japanese female pedestrian based on a movie of gait of a elderly volunteer. Then we constructed a multibody-FE hybrid model and evaluated the risk of hip fracture taking into account gait motions of elderly female. Simulation results showed that the risk of trochanteric fracture at pelvis grounding increases with gait velocity while the risk of intracapsular fracture at knee grounding is independent of gait velocity.
