Trabecular bone adaptation with an orthotropic material model

A quasi-brittle continuum damage finite element model of the human proximal femur based on element deletion

“…Several recent approaches have been developed to assign the anisotropic orientation of bone as a function of its cortical and trabecular structural morphology and mechanical behavior. These approaches include orientation methods using anatomical directions corresponding to the bone shape [7,26,38,90], variation in the CT Hounsfield unit values based on micromechanical considerations [30,66,73,76], bone remodeling simulation prior to fracture prediction to obtain the bone orthotropic orientation and elastic assignment [11,17,20,40,51], and a procedure to orientate orthotropic properties in a proximal femur FE model using the directions of the principal stresses produced by a physiological load scheme [64]. Empirical relations between the orthotropic constants and bone density have been suggested by several authors [29][30][31][32][33][34].…”

Numerical Simulation of Bone Remodeling Process Considering Interface Tissue Differentiation in Total Hip Replacements

“…In fact, it has been shown that these models are able to reproduce the normal architecture of bone. The studies [4,5,9,10,21,22] are examples of bidimensional simulations, while in [16,18,23,24] 3D results are found. These models have also been used to predict the osteoporosis process [25] as well as effects related to the resorption phenomenon in host bone due to orthopedic implants [3,6,8,11,[26][27][28][29].…”

The Influence of Mechanical, and Material Factors on the Biological Adaptation Processes of the Femoral Bone Implants

“…The issue of mutual relationships between the state of stress and deformation, and the state of bone tissue surrounding implants, which is presented for hip joint endoprosthesis in a particularly extensive way and described in a lot of studies, is equally important [1][2][3][4][5]. The biological adaptation processes of the femoral bone implants showed Philips et al [14] and Miller et al [15].…”
