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.
