Phantom Model. The phantom model enables the migration simulation of the implant according to a zero relative prosthesis-bone motion and a relative prosthesis-bone motion protocol. For the relative prosthesis-bone motion protocol the inner cylinder must be rigidly fixed to the phantom model basic (image in upper left corner). The prosthesis components investigated were rigidly fixed onto the Plexiglas beam. This beam can be positioned within the Plexiglas tube using micromanipulators for translation and rotations. Three rotational and one translational manipulator were used, whereby the single translational manipulator was repositioned to allow translational motion about each of the three axes of motion investigated.
