Abstract: A surgical guide system includes a shell trial having a convex side configured to engage an acetabulum, a concave side forming a cavity therein, and windows extending through the convex and concave sides for viewing bone. The system further includes a liner trial having a convex side configured to be received within the cavity of the concave side of the shell trial, and a concave side with recessed hole guides there, wherein more than one of the hole guides align with the windows of the shell trial when the liner trial is received therein. The system further includes an acetabular cup implant having a convex side configured to engage an acetabulum, a concave side, and a thickness extending between the concave and convex sides, the concave side defining a cavity configured to receive the liner trial.
