A femoral prosthesis for implantation by cementation, has the stem with a longitudinal borehole extending proximally to distally for the transprosthetic application of the bone cement. The prosthesis stem is surrounded by an elastic sheath of a biocompatible polymeric material in such a way that, on application of the cement, the sheath is filled advancing distally to proximally and, when the space between stem and bone bed is completely filled, pressed flush against the bone bed.
