  • TOOL SYSTEM FOR REMOVING PROSTHETIC CEMENT FROM A BONE OF A PATIENT UNDERGOING A JOINT PROSTHESIS REPLACEMENT OPERATION
    Publication number: 20240108390
    Abstract: A method for providing a tool system for removing prosthetic cement from a bone of a patient undergoing a joint prosthesis replacement operation includes scanning the patient in the area of the joint prosthesis to obtain a profile of a line of intersection of a prosthetic cement/bone interface at its intersection with a longitudinally pre-selected plane; providing a guide member shaped as a stem of the prosthesis in a prosthetic cavity located in said prosthetic cement; and providing a cutting tool for forming a running cut through the prosthetic cement along the line of intersection. A stem of the cutting tool includes two protrusions along the length thereof. A guide member includes two grooves which each engage one of said protrusions. Grooves are profiled so the outer end of the stem is forced to follow a path corresponding to the profile of the line of intersection of the cement/bone interface.

  • A TOOL SYSTEM FOR REMOVING PROSTHETIC CEMENT FROM A BONE OF A PATIENT UNDERGOING A JOINT PROSTHESIS REPLACEMENT OPERATION
    Publication number: 20210251673
    Abstract: A method for providing a tool system for removing prosthetic cement from a bone of a patient undergoing a joint prosthesis replacement operation, comprising the steps of: scanning the patient in the area of the joint prosthesis so as to obtain at least one profile of a line of intersection of a prosthetic cement/bone interface at its intersection with a generally longitudinally pre-selected plane; providing a guide member substantially shaped as a stem of the prosthesis in a prosthetic cavity located in said prosthetic cement; providing a cutting tool for forming a running cut substantially completely through the prosthetic cement along the line of intersection; wherein a stem of the cutting tool comprises two laterally extending protrusions, which protrusions are located along the length of the stem at a mutual distance apart; and wherein the guide member is provided with two longitudinally running grooves which each engage one of said protrusions of the cutting tool, wherein the grooves are profiled such th
