2129894 9317634 PCTABS00025 The base (1) includes an outer body (2) of biocompatible metallic material with a cavity (3) in which an inner body (4) of biocompatible metallic material with a seat (8) for holding a prosthesis is disposed with the interposition of a layer (5) of shock-absorbent material. An annular retaining element (10) connected to the edge of the cavity (3) in the outer body (2) has a resiliently-deformable inner edge (10b) which engages a corresponding outer collar (4a) on the inner body (4) so as to be resiliently preloaded thereby.
