The Variation of Orthotropic Elastic Constants in the Female Anterior Femoral Midshaft: a Micro-finite-element Study
نویسندگان
چکیده
INTRODUCTION Computational modelling in orthopaedic biomechanics often uses continuum homogenised finite element models of the bone which require accurate definitions of its elastic properties. In this study the variation of the orthotropic elastic constants of cortical bone from the female anterior femoral midshaft were evaulated. Micro-finite-element (μFE) analysis of bone samples from 27 female donors aged between 20 – 87years were conducted to quantify the elastic constants at the periosteal and endosteal aspects. The variation of properties with age and canal volume to total volume (Ca.V/TV) were evaluated.

This work presents a numerical approach in order to predict the influence of implant material stiffness in a femoral component design when submitted in compression. The implant success depends on the transferred load to the neighboring bone. The finite element method can be used to analysis the stress and strain distribution in the femoral component allowing to improve the implant selection. Fo...
متن کاملElastic Properties of the Human Proximal Femur
This chapter examines the effects of femoral neck geometry and topological structure on elastic properties. A finite element code is used to calculate the full elastic tensor for thirteen human proximal femur specimens. We show that the micro-structure within the human femoral neck and head gives rise to approximate orthotropic elastic symmetry at the whole bone scale. The finite element code c...
