| Abstract: | In this article, the human lumbar spine region, af-fected by osteoporosis, L4 vertebra modelling and stability analysis are presented. Tissue degradation problem was ex-amined. Spatial numerical model in SolidWorks computer program environment was done. Numerical experiment was done in finite element method in ANSYS Workbench envi-ronment. This article is also given with calculation results, when the compression force and the compression force with tension are applied. Model’s cases for loss of load bearing capacity are examined with simulating aging and osteopo-rosis effects, which occurs with aging of the tissue. Degra-dation of the tissue is modelled while applying expressions determined with empirical approach, which link depend-ency between mechanical properties and porous bone den-sity. |
