The aim of this study was to provide a fast and accurate finite element (FE) modeling
scheme for predicting bone stiffness and strength suitable for use within the framework of a
computer-assisted osteoporotic femoral bone augmentation surgery system. The key parts of
the system, ie preoperative planning and intraoperative assessment of the augmentation,
demand the finite element model to be solved and analyzed rapidly. Available CT scans and
mechanical testing results from nine pairs of osteoporotic femur bones, with one specimen …
