Abstract
A prosthesis for at least a portion of a bone, in particular a bone or portion thereof to which, in the natural condition, a tendon of a muscle is attached, wherein the prosthesis is manufactured of a metal or an alloy thereof and is provided with at least one area situated in the surface of the prosthesis that faces outward once the prosthesis has been placed in the body, the area being formed by a layer provided with open spaces that are connected to each other, wherein the open spaces are dimensioned for allowing the growth of bone tissue therein.

A prosthesis for at least a portion of a bone of a body, in particular a bone or portion thereof to which in the natural condition a tendon of a muscle is attached, wherein the prosthesis is manufactured of a metal or of an alloy thereof and is provided with at least one area situated in the surface of the prosthesis that faces outward once the prosthesis has been placed in the body, said area being formed by a layer of material provided with open spaces that are connected to each other.
A method for arranging a prosthesis for at least a portion of a bone of a body, in particular a human body, in particular a bone or portion thereof to which in the natural condition a tendon of a muscle is attached, wherein the prosthesis for at least a portion of a bone of a body, in particular a bone or portion thereof to which in the natural condition a tendon of a muscle is attached, wherein the prosthesis is manufactured of a metal or of an alloy thereof and is provided with at least one area situated in the surface of the prosthesis that faces outward once the prosthesis has been placed in the body, said area being formed by a layer of material provided with open spaces that are connected to each other, comprising the following steps:
- a—detaching tendons from the bone area to be replaced and removing the bone area to be replaced;
- b—positioning the prosthesis at the wanted location;
- c—at least temporarily securing the tendons, with their original enthesis in a bone fragment, on the prosthesis, in engagement with the said porous areas;
- and
- d—promoting the formation of bone tissue in the open spaces of the porous areas and through bone healing allowing the bone fragment to attach to the bone tissue formed in the pores in the said area of the prosthesis.
