Popis: Fractures in trabecular bone are due to degradations: bone density decreases and microarchitecture is altered with respect to aging. Many authors aimed modelling degradation of trabecular bone architecture due to aging or disease ([Adachi, 2001], [Muller, 2005], [Liu, 2008]). The precited models were only based on biological kinetics and parameters: lengths of apposition and resorption phase, depth of resorption lacunae, frequency activation... However, models considered millions of elements and did not integrate mechanical stimulus as a precursor of bone remodelling adaptation. As a result, they have simulated the micro-structure degradation and not the influence of mechanical stimulus on bone stiffness.
