International Classification:

US Classification:

623 22

Abstract:

A prosthetic device adapted to be secured to a supporting bone by a thickness of acrylic bone cement. The prosthetic device has an outer surface which includes a plurality of spacers projecting therefrom. The spacers are made of an acrylic material, such as polymethyl methacrylate (PMMA), and are adapted so that when the prosthetic device is positioned against the supporting bone, the spacers provide a uniform space between the bone and prosthetic device, thus uniformly controlling the thickness of cement. The acrylic spacers will repolymerize and bond with the layer of acrylic bone cement. The nature of the bond formed between the new acrylic bone cement and the acrylic spacers should eliminate the stress concentrations at the interface between the spacers and the cement layer, thereby enhancing fixation of the prosthesis.
