  • Publication number: 20190142597
    Abstract: Apparatuses, kits, and methods for cementing an orthopedic implant to a bone, post attachment, are disclosed in some aspects of the present disclosure. A kit can include a prosthetic component and a cement applicator. The prosthetic component can include an attachment profile that corresponds to a mating profile formed on or in a bone. The cement applicator can be configured to apply a bone cement between the bone and the prosthetic component following alignment between the prosthetic component and the bone or another prosthetic component. The kit can also include a bone cement. A method can include positioning the prosthetic component adjacent to the bone, aligning the prosthetic component relative to the bone or another prosthetic component, and applying a bone cement between the bone and the aligned prosthetic component.

  • Patent number: 7037311
    Abstract: A tool for gripping an orthopedic implant having a recess. The tool includes a plurality of engagement members which extend freely from the tool body to their free ends. An elongate biasing member having a radially enlarged portion at its distal end is positioned along a central axis of the tool with its radially enlarged portion positioned between the engagement members. Axial translation of the biasing member biasingly engages the radially enlarged portion with the engagement members and resiliently deflects the engagement members from a contracted position to an expanded position. The engagement members are insertable into a recess in the implant when in the contracted position and outward biasing of the engagement members firmly secures the implant to the tool. The use engagement members which define a non-circular cross sectional shape and a correspondingly shaped recess in the implant inhibits relative rotational movement between the tool and implant.

  • Publication number: 20040010261
    Abstract: A tool for releasably gripping an orthopedic implant. The tool includes a first gripping member which may be a threaded shaft and a second gripping member which may be the tool body. The first gripping member has a gripping end engageable with the implant and secures the implant to the tool with a bearing surface located on the distal end of the tool engaging the implant. The distal end may also include a feature to rotationally engage the implant and resist relative rotational movement between the tool and implant. A release mechanism is provided which, when the implant is secured to the tool, is operable to release the gripping members from their relative positions and retract the bearing surface from the implant. The first gripping member which then only loosely engages the implant may be completely disengaged from the implant. The release mechanism may be a pivoting lever body.
