Abstract
A prosthetic acetabular component includes two constructs, one being a metal base construct that engages the bone and the other being a polyethylene bearing construct that attaches to the metal base construct and articulates with a femoral stem prosthetic component. The metal base construct is composed of two different metals, one of which engages the bone surface and the other of which engages the polyethylene bearing construct. Each metal is well suited to its function. The first metal provides a superior bone-engaging face, while the second metal provides a superior polyethylene-engaging face.
