Title: Material for making bone endoprosthesis and endoprosthesis made of said material
Abstract:
A material for making a bone endoprosthesis having a reinforcing base composed of nets which are made of a chemically and biologically inert metal and elastic polymeric material. The entire space confined within the nets is occupied by the binder doped with an antiseptic, the volumetric ratio between the metal nets and the entire material being selected such that the modulus of elasticity of the material approximates that of the bone tissue to be replaced. An endoprosthesis of the invention is cross-sectionally shaped as a row of spirals made of the proposed material and interlinked through an element made of the same network material, while the entire space between the prosthesis components is embedded in the binder. In an embodiment of the present invention, the endoprosthesis has a spiral sheath made of the proposed material. The interior space of the sheath accommodates several spirals, each comprising a number of spirals interlinked by the element made of the proposed network material.
