| Research Abstract |
Although the relationship between the contour and stress or micro-motion at the fixation site has been analyzed, guidelines on stem design have not been established. Contact stress at the fixation site of a joint prosthesis was analyzed by an explicit three-dimensional finite element method. The situation of the initial fixation about the specific part which becomes important clinically based on the results was clarified. This study highlights the mechanical instability of the fixation site of joint prostheses, and thus suggests that the general idea that unconditionally recommends a larger area for the fixation site of joint prostheses should be revised.
