A prosthesis comprises a metal member of for example titanium or tantalum and includes a solid core or substrate and a covering of perforated metal of a porous nature. The perforations are preferably arranged in the foil so that when laminated the complete covering has pores of irregular shape. This irregularity assists in the keying of bone substance to the prosthesis. The minimum pore transverse dimension is 50 microns.A method is also described which involves dipping the member into a suspension of the hydride of the member of the core and subsequently heating the core at high temperature.
