Originální abstrakt

In the endoprosthesis surgery there is a large percentage of implant defects, which cause the failure of the whole prosthesis. One kind of the total hip replacement functionality loss is acetabular cup pull-off from pelvis bone. This article is aimed at manufacture perturbations analysis as one of the possible reasons to this kind of failure. Dimension and of geometry (roundness) manufacturing perturbations were analyzed. It was found, that these perturbations affect considered values of contact pressure and frictional moment. Contact pressure and frictional moment are quantities affecting replacement success and durability.
