Femoral Postoperative Bone Adaptation – Numerical Calculation and Clinical Validation with DEXA Investigations

authored by: Anas Bouguecha, Bernd Arno Behrens, Matthias Lerch
Abstract: Nowadays the finite element method (FEM) presents an established tool in the field of biomedical engineering and is applied for the numerical simulation of several biomechanical phenomena. Nevertheless, the accuracy of the simulation results essentially depends, on the material modeling. To point this up, FE computations of the strain-adaptive bone adaptation (remodeling) after total hip arthroplasty (THA) are presented in order to predict the secondary stability of the prostheses. Reliable calculation results are possible here only, if prerequisites are fulfilled. These include especially an accurate mathematical model for the description of the postoperative changes in the apparent bone density (ABD). In addition, clinical studies play a crucial role in the validation of these complex computations. In this context corresponding DEXA (dual-energy x-ray absorptiometry) investigations are presented in this work.
