  • Publication number: 20230277325
    Abstract: A method for replacing a joint at an end of a bone includes resecting an end of a bone so as to form a resected surface. A cement restrictor is inserted into an intramedullary canal of the bone. A filling prosthesis is implanted into the intramedullary canal in a press-fit manner. The void filling prosthesis has a channel that extends entirely through the void filling prosthesis. Bone cement is injected into the intramedullary canal between the bone restrictor and the resected surface so that the resected surface remains free of the bone cement. The bone cement is then pressurized. A joint prosthesis is implanted onto an end of the bone such that a porous bone facing surface of the joint prosthesis directly contacts the resected surface and a stem of the joint prosthesis extending from the porous bone facing surface is positioned within the pressurized bone cement.
