In spite of care taken in endoprosthetic joint replacement, migration of prosthetic components from fractions of a mm to one cm or more can occur. To detect such "micromotion" in a clinical environment, it is proposed that the positions of radiopaque markers implanted in both the prosthesis and the host bone and positions of their images on two or more conventional X-rays be used in a mathematical model. One implementation illustrates that estimates to within 0.5 mm are possible using prototype models.
