Abstract
In this study, FEM was used to analyze the stress at the interface between a prosthetic stem and femur. FE models of three contemporary stems were constructed for a computer simulation. As the results, it was found that the stress distribution on the PerFix SV (PSV) stem .uctuated with a slight disturbance. On the Intra-Medullary Cruciate (IMC) stem, the high stress areas were distributed on the proximal area and under the pin. The high stress area on the VerSys (VS) stem spread on the medial side. It was shown as the results that the stress on the stem which was designed for wide .xation area was apt to localize in the inadequate area. This .nding was veri.ed by the experiments using the loading tests on the actual stems with stress .lms and a stress sensor.
