Abstract: A spinal disc nucleus replacement including an elastomeric sheath (12) assembled around a rod (14), a portion of the sheath being arranged for sliding along the rod, and a sheath compactor (18) adapted to slide a portion of the sheath along the rod from a first position to a second position, wherein in the first position the sheath is in a non-expanded orientation and in the second position the sheath is in an expanded orientation wherein folds of the sheath expand radially outwards from the rod.

Abstract: Spinal apparatus is disclosed that includes reference structure spatially fixed relative to a plurality of pedicle screws that are mounted in adjacent vertebrae of a patient, and a device connected to the reference structure which is adapted to install an anterior spinal prosthesis, wherein the reference structure defines a spatial relationship between the anterior spinal prosthesis and a posterior spinal prosthesis attached to the pedicle screws.

Abstract: A spinal prosthesis including a first spinal attachment member attachable to a first posterior portion of a spinal structure, a second spinal attachment member attachable to a second posterior portion of the spinal structure, the first and second posterior portions being adjacent superiorly-inferiorly to one another, and a connector element attached to the first spinal attachment member, wherein the second spinal attachment member includes an interface portion that passes through an elongate aperture formed in the connector element so as to permit rotational and translational movement of the second spinal attachment member with respect to the connector element.

Abstract: An endoprosthesis including a first articulating member formed with a generally concave articulating surface, and a second articulating member formed with a generally convex articulating surface which articulates with the concave articulating surface, the first and second articulating members each having a generally planar attachment surface for attachment to spine structure, wherein the first articulating member includes a contour defined by a cutting surface that cuts through a portion of the first articulating member at a non-zero angle relative to its attachment surface, and the second articulating member includes a contour defined by a cutting surface that cuts through a portion of the second articulating member at a non-zero angle relative to its attachment surface.
