Abstract

In this study a three dimensional finite element model was established to analyze the interfacial stress distribution in the osseointegrated transfemoral prosthesis. The effects of implant length and screw pitch on the stress and strain distributions were analyzed in terms of bonded and contact bone-implant interfaces. The influences of the contact parameters, contact stiffness and friction coefficient, of the model were evaluated. The results show the differences on the stress distributions at the bone-implant interface in the models with different implant lengths and thread pitches. The highest stress in the model with contact interface is higher than that in the bonded model
