Description / Abstract:
This practice describes a method for the fatigue testing of
metallic stemmed femoral components used in hip arthroplasty. The
described method is intended to be used to evaluate the comparison
of various designs and materials used for stemmed femoral
components used in the arthroplasty. This practice covers
procedures for the performance of fatigue tests using (as a forcing
function) a periodic constant amplitude force.
This practice applies primarily to one-piece prostheses and
modular components, with head in place such that prostheses should
not have an anterior/posterior bow, and should have a nearly
straight section on the distal 50 mm of the stem. This practice may
require modifications to accommodate other femoral stem
designs.
The values stated in SI units are to be regarded as the
standard.
