ABSTRACT OF THE DISCLOSURE A prosthesis shaft is provided for the implantation of a prosthesis, particularly a part of an artificial hip, knee or finger joint, which may be securely and permanently anchored within the bone by the use of a glass ionomer-type bone cement characterized by the desirable properties of bio-inertness and very good compressive strength. The shape of a prosthesis shaft according to the present invention makes the use of glass ionomer-type bone cements practical, because the shaft exerts substantially only compressive forces on the cement, largely avoiding tensile and notch stresses to which this kind of cement exhibits little resistance.
