An acetabular cub system is configured to be secured to a pelvis and may include an acetabular cup and a plurality of bone fasteners. The acetabular cup may include a bone engaging surface and an articulating surface, as well as a plurality of lobed fastener apertures extending from a first opening at the articulating surface to a second opening at the bone engaging surface. The plurality of bone fasteners may be insertable through the lobed fastener apertures to secure the acetabular cup to the pelvis. Each of the plurality of lobed fastener apertures may include a central aperture configured to receive a first bone fastener of the plurality of bone fasteners and one or more aperture lobes intersecting with the central aperture configured to receive a second bone fastener of the plurality of bone fasteners. The central aperture may be larger than the one or more aperture lobes.
