Patent ID: 8864826

Claim:
Integrated prosthetic element usable for bone implant operations as a femoral, shoulder or knee prosthesis, or as a bone filler or replacement, insert or shell, comprising at least a metal support and an insert made of plastic material coupled with at least a first surface of said metal support so as to define a wear surface, or insert, of adjustable thickness, said metal support comprising, on a side opposite said first surface, a second surface intended to be coupled with the bone part on which the prosthesis or bone replacement is installed, wherein said first surface comprises a solidarization layer, having cavities or holes which extend internally said first surface and are distributed in a substantially uniform manner and suitable for anchorage and solidarization of the plastic material that makes up the insert, while said second surface comprises a porous layer suitable to optimize the bone anchorage, wherein said first surface and said second surface are separated by a compact layer, and wherein the cavities or holes of the first surface have bigger shapes and sizes than the pores of the second surface, and wherein the metal support, with the solidarization layer, the compact layer and the porous layer are all obtained using either the Electron Beam Melting Technique (EBM), or a technique using a high power laser ray, from a powder material based on pure titanium, or an alloy thereof, or cobalt alloys, tantalum alloys or other suitable biocompatible alloy, and wherein said cavities or holes extend toward the inside of the solidarization layer and create at least undercuts, or have a series of open cavities intercommunicating and connected with each other.
