| Summary: | Osteogenesis imperfecta (OI) is a fragile bone disease characterized by easy
fractures. The femur consists of cortical and cancellous bone, each with different mechanical
properties. Bone fractures often occur throughout patients’ lifetime. However, doctors still
have no quantitative method to predict fractures. This project’s purpose is to investigate the
mechanical behaviour of patient-specific OI femur from the finite element analysis. The
fracture risk in daily activities (ADL) were examined. All the stress values were judged by the
fracture criteria, assumed as 115 MPa. The exercises that exerted force more than 6 times of
body weight could cause fractures. Cancellous bone was not affected in any case of ADL. The
effects of force and stress on cancellous bone and its impact on fracture risk are negligible. |
