Study Arms:
- Ceramax COC 28mm Acetabular Cup (Type: None): The 28 mm ceramic acetabular bearing insert component is manufactured from high purity, dense alumina matrix composite ceramic. The inserts secure to DePuy's Pinnacle acetabular shells by means of an interlocking mechanical taper. The Pinnacle acetabular shell is a hemispherical type acetabulum replacement prosthesis, is available in a range of outer diameter (OD) sizes, and is used with a 28mm femoral head. Pinnacle 100 shells will be used in this study. The BIOLOX® delta ceramic femoral head components are manufactured from the same ceramic material as the acetabular bearing insert components. The femoral head is secured to the femoral stem component with an interlocking taper.

Based on this trial design, predict the completion outcome and termination type (if applicable).
