A multi-layered prosthetic element comprises a central body (1 1) of a substantially truncated conical shape and having a through axial cavity (2 2) open at both ends which gives the central body (1 1) a ring-shaped cross-section. The central body (1, 1) comprises an outer portion (110 110), made of trabecular metal material, an inner portion (130 130), made of trabecular metal material, and an intermediate portion (120 120) made of metal material without significant porosity. The outer portion (110 110) and the inner portion (130 130) are integrally connected to the intermediate portion (120 120). The intermediate portion (120 120) is configured to mechanically resist to stresses transmitted to the inner portion (130 130) on one side and to the outer portion (110 110) on the other side.
