  • Publication number: 20200078186
    Abstract: An implant couples a first bone of a hand to a second bone of the hand. The implant includes a body that defines a median plane. The body also defines a first joint surface having a first central region that articulates with the first bone. The body further defines a second joint surface having a second central region that articulates with the second bone, and the second central region is disposed on an opposite side of the median plane of the body relative to the first central region. The first and second central regions correspond to profiles of first and second axial segments, respectively, the first and second axial segments are each one of a cylinder, a cone and a torus and are centered on first and second axes, respectively, and the first and second axes, as projected on the median plane, are substantially perpendicular to each other.

  • Publication number: 20160331555
    Abstract: Methods of implanting a prosthesis to repair a joint include displacing a first bone from the joint formed by an intersection between the first bone and a second bone. An end portion of the first bone is resected to define a resected end. A concavity is formed into the resected end using a shaping tool. The bone is compacted to form a support layer lining the concavity. The prosthesis is implanted in the concavity against the support layer without attaching the prosthesis to the support layer. The joint is reformed with the prosthesis such that the prosthesis remains unattached to the support layer and the first and second bones articulate about the prosthesis.

  • Patent number: 8088168
    Abstract: A method and apparatus for replacing an articular surface of a bone. The implant includes at least one head with a bore and a lateral articular surface generally perpendicular to an axis of the bore. A holding element includes a stem at a proximal end adapted to attach to the bone. A member at a distal end of the holding device is adapted to engage with the bore in the head so that the lateral articular surface is positioned to engage transverse loads. The bore permits limited lateral translation of the head in at least one direction generally perpendicular to a longitudinal axis of the member.

  • Publication number: 20110130844
    Abstract: The invention relates to an articular resurfacing implant which is characterized in that it is composed of a sheet (1) of pyrolytic carbon deposited on a graphite substrate and a layer (8) composed of an adhesive elastomer or polymer material adherent to the inner surface of the sheet (1) on the substrate side. The adhesive elastomer or polymer material layer (8) allows the implant to be adherent to bone (3) and acts as a shock absorber layer. In one embodiment the implant further comprises a hard material, e.g. metallic, sheet (4).
