Abstract
The use of Finite Element Modeling (FEM) is a valuable tool in the field of orthopaedic implants. In the present projects we emphasized the use of geometrically realistic models and easy understandable results to improve the dialogue with the orthopaedists. We built up models of femurs with and without prosthesis. The bone geometry and material properties were first obtained by dissection and literatur, later on by using a quantitative CT scanner (QCT). The implementation of an interface between QCT and pre/postprocessing program increased the speed of modeling a long bone dramatically. Bevore modeling an implant-bone system, the relative positioning of prosthesis and bone was determined by performing an implantation simulation with the help of solid modeling. Based on the use of three dimensional displays, the discussions with the surgeon during modeling and after the calculation enhance the understanding of the modeled system, as well as the interpretation of changes found in histologic examinations.
