摘要: In this study, we developed a numerical framework that computationally determines simultaneous and interactive structural changes of cortical trabecular bone types during remodeling, investigated the correlation between two in human proximal femur. We implemented surface remodeling technique performs exterior layer while keeping its interior area unchanged. A micro-finite element (μFE) model was constructed represents entire full architecture This study simulated compared adaptation processes different structures: (1) femoral has normal shape (2) perturbed an artificial lump inferomedial cortex. Using proposed method conjunction with design space optimization, successfully obtained results resemble actual The revealed bone, as well femur structurally optimal shapes, it also shown abnormality little contribution to integrity tends disappear. quantitatively determined each bone: when complete, supported 54% total load carried 46%.
