    Abstract

    Understanding the mechanism of osteoporotic femoral neck fractures is important for improving diagnosis and treatments of osteoporosis. Standard mechanical testing can measure the femoral stiffness and strength under different loading scenarios. However, it does not provide information about internal deformations and location of fracture onset. A combination of time-elapsed micro-CT imaging, step-wise loading and Digital Volume Correlation (DVC) has been already used for measuring deformation within trabecular bone specimens [1] and vertebral bodies [2] but its application to images of specimens as big as the proximal human femur is challenging. The goal of this study is to develop a protocol to measure the full 3D field distribution of strain, from the elastic range up to failure, in the entire human proximal femur.
