Abstract:
An intervertebral disc prosthesis comprises a first prosthesis component, a second prosthesis component, and an intermediate prosthesis component positioned between the first prosthesis component and the second prosthesis component. The first prosthesis component and second prosthesis component are configured to rotate upon the intermediate prosthesis component. The first prosthesis component includes a vertebra facing surface with a central channel formed in the vertebra facing surface. The central channel is designed and dimensioned to engage an insertion arm of a disc insertion tool. The first prosthesis component also includes at least one indentation configured to engage at least one retention arm of the disc insertion tool. The at least one indentation of the first prosthesis component may comprises at least one groove formed in a collar of the first prosthesis component. In one embodiment, the first and second prosthesis components are plates and the intermediate prosthesis component is a core.
