  • Publication number: 20200146833
    Abstract: An artificial knee that has first and second knee components connected together for rotation between a first, upright position and a second position where one knee component is positioned at an angle to the other, an alignment mechanism associated with the first and second knee components to assure rotation in a vertical plane from the first position to the second position, and a biasing member. One knee component includes an extension member located in a central location, while the other includes a centrally located slot that receives the extension member and allows rotation only in a vertical plane. The biasing member normally holds the knee components in the first position, such that rotation of the first knee component away from the second knee component stretches or elongates the biasing member to provide a force that urges the knee components to move back to the first position.

  • Patent number: 10405985
    Abstract: An implant includes a fixed bearing, a floating bearing, and a coupling member. The fixed bearing defines a generally first spherical articulating surface and a stop. The floating bearing includes a second spherical articulating surface and a planar articulating bearing surface. The coupling member defines a bearing surface that translates relative to the planar articulating bearing surface.

  • Patent number: 10251690
    Abstract: An instrument for internal bone fracture fixation includes a shaft having a distal portion and a patient-specific bone holder coupled to the distal portion. The bone holder has a three-dimensional curved and patient-specific bone engagement surface designed during a preoperative plan based on a medical scan of a patient to match and conform to an outer surface of a bone fragment of the patient in only one position.

  • Publication number: 20180132871
    Abstract: A patient-specific guide tool for guiding an object toward a glenoid face of a scapula of a patient for implantation of a shoulder prosthetic device is disclosed. The guide tool includes a guide portion that includes a guide surface. The guide surface is configured to guide movement of the object toward the glenoid face. Furthermore, the guide tool includes a patient-specific portion that is operably coupled to the glenoid portion. The patient-specific portion includes at least one patient-specific surface that is three-dimensionally contoured and that is configured to nest and closely conform to a corresponding surface of the scapula to thereby position the guide surface at a predetermined position relative to the glenoid face.
