ABSTRACT:
The wire mesh is welded to the metal substrate via step-like protuberances formed on the outer surface of the substrate. The wire mesh is permanently deformed in the regions over the protuberances to facilitate forming of spot welds while the remainder of the mesh outside the zones of the protuberances remains porous for the intake of bone cement or the ingrowth of bone tissue.
