Abstract
A metal backing for inclusion in the manufacture of a prosthetic component having a plastic bearing element on an upper surface and has a bottom surface portion with elements for attachment to a bone. The backing has an upper surface portion at least part of which is formed by a grill element having exposed front and rear faces and which is intended to be embedded within the plastic bearing member during construction. The plastic bearing material of the bearing element can be molded so that all the faces thereof exposed to the grill are covered and the grill is embedded within the plastic material of the bearing element. The grill is located on a metal support and is provided with spacers on its front face to space the front face away from the support. The grill is cast integrally into the metal support during manufacture.
