Abstract
In this presentation a consistent combination of computational mechanics simulation with established imaging methods in medicine is outlined. In a first step a finite element model is built up from CT-data, which includes information on the geometrical shape and the interior material distribution. The reconstructed bone mineral density distribution describes the basic input for the computation of the so called static-equivalent load set for joint loads and muscle forces as boundary conditions for the long term stability simulation of artificial hip joints. A novel model refinement is presented on the incorporation of the osseointegration process, which describes implant ingrowth behavior. A bioactive contact-theory for the computer simulation of these processes is presented. Because quite different biological processes are responsible for the osseointegration of bone implants, quite different time scales have to be taken into account while individual motion activity has to be considered. The improvement of the predictive character of this advanced computational approach will be underlined by clinical investigations.
