Özet
The purpose of this study was to investigate numerically the effects of
the inclination (collodiaphyseal) angle and bone cement (polymethylmethacrylate) filling on the stress distribution of human femurs and
implants after the implementation of a partial endoprotez arthroplasty.
Ti6Al4V, which is the most commonly used implant material, was
choosen for this study. In the numerical study, solid models of implants
and femurs were created using the SolidWorks 2010 package program,
then stress analyses were carried out at five different inclination angles,
120°, 125°, 130°, 135° and 140°, with and without bone cement
(polymethylmethacrylate), using the ANSYS Workbench 12.0 package
program. The anteversion angle was assumed to be 12.5° for all models.
As a result of the increase in the inclination angle and the addition of
bone cement, it was determined that the stress values of the femurs and
implants were reduced. Within the limitations of this study it has been
shown that parameters like bone cement, anteversion angle, and an
appropriate inclination angle should be tested previous to partial
endoprosthesis arthroplasty surgery necessary as a result of damage to
the human femur.
