Bone Biomodel for Mechanical Simulation Using Finite Elements

Latest computational technologies and engineering improvements have allowed biomodels development addressed to biological systems (bones), for which detailed studies and structural mechanic analysis are fundamental. Those mentioned above are narrowed to diagnose diverse conditions (such as osteoporosis). Additionally, biomechanics is in charge of describing the human body's structural components. That being said, biomodels patterns with natural osseous characteristics could be made to seem more factual situations of real service conditions through finite element methods application, and the final results might be close to reality. Nevertheless, implementing concepts of linearity, isotropy, continuity, and homogeneity is mandatory to develop a basic structural study through mechanics theory and get evidence. By implementing close-to-reality tests in biomechanics, it is necessary to exceed the conditions above (linearity, isotropy, continuity, and homogeneity). Lately, these conditions have surpassed themselves by numeric development analysis. However, biological system homogeneity implies great difficulty and significant computational resources. This contribution shows a methodology that implements a natural system numerical model by considering bone porosity and comparing it to a model that does not concern bone porosity. In the same way, both models are obtained, considering that they are set up by cortical and trabecular bone. Afterward, in the results, clear effects that make bone porosity can be observed, and be discerned for future implementations in the surgical and medical sectors.
