Abstract

AbstractThe paper deals with the problem of determining of parameters describing the degree of trabecular bone structure anisotropy. The Mean Intercept Length (MIL), the most commonly used characteristics of anisotropy in trabecular bone, was taken as a gold standard method. As an alternative description, an approach was proposed in which the degree of anisotropy was defined as the ratio of the apparent modulus determined by mFE in two orthogonal directions. For the analyses, an important issue was to determine the direction of occurrence of the maximum value of the apparent modulus. The paper also presents the procedure of calibrating the numerical model in terms of the correct definition of the boundary conditions for analyses carried out with trabecular tissue samples cut at rotated coordinate system.KeywordsCancellous tissueApparent stiffnessmFE analysisMIL method
