  • Patent number: 11504243
    Abstract: The present application relates to an assembly for a joint (1, 2, 3, 4), the joint comprising a joint implant (5, 6) between a proximal segment of a limb that is proximal to the joint and a distal segment of the limb that is distal to the joint and in which the joint is configured to allow rotation of the proximal and distal segments with respect to one another about an axis that intersects a first plane, and to inhibit rotation in the second and third plane, both perpendicular to the first plane, the assembly being for subjecting the joint at predetermined angles of the joint rotation in the second and third plane to a defined bending moment to induce a load to the implant that causes a movement of the implant in relation to the bone of the proximal or distal segments.
    Type: Grant

  • Patent number: 6161080
    Abstract: The present invention relates to a method of generating a three dimensional representation of one or more anatomical joints, wherein the representation comprises two or more movable bodies and one or more links, comprising the steps of inputting anatomically representative data of two or more movable bodies of the selected joint or joints; selecting one or more link types responsive to the representative data of the bodies; selecting link characteristics responsive to each selected link type; generating an equilibrium condition responsive to interaction between the bodies and the links; and displaying a three dimensional representation of the selected joint or joints responsive to the data generated from the equilibrium condition of the anatomical joint or joints. The present invention further relates to a system for generating a three dimensional representation of one or more anatomical joints, and a method of planning surgery of one or more anatomical joints.
