Analysis of 3-D micromotion of porous-coated femoral prostheses

Abstract

A video image tracking system for the micromotion analysis of the total hip replacement (THR) design is presented in this paper. Micromotion with optimal amount of translation and rotation is crucial for the ingrowth of bone tissue on the prosthesis surface. By sampling the input sequential images from the video camera, low-level image processing technique is applied to get the information about the micromotion on the bone/implant interface.<>
