Abstract

An implant system includes an acetabular implant and a bone screw having an articulated screw head which allows an unchanged contact position of the screw head on the acetabular implant when the bone screw is aligned relative to the acetabular implant. For this purpose, a slotted hole is made in the acetabular implant in which slotted hole the bone screw can be pivoted in longitudinal direction of the slotted hole.
