Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. An implant may include abuse member that has at least two projections with a gap between the projections. The gap between the projections allows the implant to be implanted around another implanted component, such as around a bone screw of an acetabular shell. The implant may include a fixation element, such as a screw or a cement trough, on one or more projections to couple the implant to an implanted acetabular shell. The implant may also include timing marks to facilitate alignment with corresponding marks on another implanted component.
