Abstract
A multi-layered prosthetic element comprises a central body (') of a substantially truncated conical shape and having a through axial cavity (′) open at both ends which gives the central body (′) a ring-shaped cross-section. The central body (′) comprises an outer portion (′), made of trabecular metal material, an inner portion (′), made of trabecular metal material, and an intermediate portion (′) made of metal material without significant porosity. The outer portion (′) and the inner portion (′) are integrally connected to the intermediate portion (′). The intermediate portion (′) is configured to mechanically resist to stresses transmitted to the inner portion (′) on one side and to the outer portion (′) on the other side.
