This device is intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across the joint. This generic type of device has a femoral component made of a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy and an acetabular component composed of an ultra-high molecular weight polyethylene containing an additive such as a-tocopherol articulating bearing surface fixed in a metal shell made of Co-Cr-Mo or Ti-6Al-4V. The stem/shell are coated with a porous coating to achieve cementless biological fixation.
