 Objectives Our research project aims to identify QCT factors that predict osteoporotic hip fracture. To this end, we will use image analysis software specially designed for proximal femur evaluation to assess 3D QCT images of the proximal femur. Femoral BMD and geometry parameters will be studied. This method has been validated experimentally. Our working hypothesis is that it will prove superior over DXA the reference standard in predicting osteoporotic Phip fractures.
