Abstract
The metal wire structure for endoprosthetics is formed of a sintered hollow mesh knitting of elastic metal wires (D), said knitting being preferably manufactured in the manner of a 'rete milanese'. Said metal wire structure is either used as a coating (1) of an endoprosthesis (3) or, after having been sintered together, as a bone replacement piece. Such a metal wire structure allows to obtain a good anchorage in the bone, since the pore size of said meshes may be adapted to the local conditions, on one hand, and on the other hand, the remaining elasticity of said meshes allows a suitable transition from said prosthesis to the bone.
