摘要

Competent fracture healing monitoring requires an extensive knowledge of the evolution of the mechanical environment of the healing bone during daily-life activities such as walking. Fractures are caused due to a traumatic incidence, while low trauma or fragility fractures can also occur due to osteoporosis. It is expected that the mechanical behavior of healing bones differs among osteoporotic and non-osteoporotic subjects. This work presents finite element simulations of gait analysis considering a fractured long bone at the hematoma stage. The aim is to investigate the evolution of the mechanical environment of the femur for an osteoporotic and a non-osteoporotic subject. This is the first computational study providing quantitative information for the impact of osteoporosis on the mechanical environment of the femur. It was shown, that higher deformation and equivalent stress values are calculated for osteoporotic bones during a gait cycle, while the highest values were observed in the femoral head.
