This thesis investigated to what extent micro-FE analysis based on high-resolution CT images can accurately estimate the material properties of intact and damaged bone tissue. To achieve this goal, the ability of micro-FE analysis to estimate the compressive stiffness of cancellous bone specimens after fracture was first tested. Subsequently, the stiffness after cementation of a fractured sample was measured and compared with the fractured and non-fractured situation. Micro-FE was also achieved to see if it can predict the stiffness of cemented bone. The second part focused on the prediction of bone strength. This was done in small animal models. Bone strength was measured by three-point flexion tests, the results of which were analyzed using beam theory. Human bone strength was then mechanically analyzed based on in-vivo HR-pQCT scans. Although this method has been validated in several studies for the first generation of this type of scanner, it has not yet been validated for the second generation of HR-pQCT devices. To this end, the optimal defects for the analysis of micro-FE and homogenized FE are presented.
