Abstract: Spinal reamer apparatus including a reference base with mounting provisions for mounting in a region of posterior lumbar spinal structure, a non-straight track fixed to the reference base, and at least one reaming cutter element arranged to move along the track.

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: 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.

Abstract: Apparatus including a first spinal prosthetic member attachable to a first spinal structure, and a second spinal prosthetic member attachable to a second spinal structure, the first and second spinal prosthetic members being movably attached to one another with a fastening device, the fastening device having a non-tightened position which permits spatial movement of the first and second spinal prosthetic members with respect to one another at a desired orientation, and a tightened position which fixes the first and second spinal prosthetic members at the desired orientation.

Abstract: An endoprosthesis including first and second attachment surfaces for attachment to spinal structure, and a fixation element rotatingly disposed in at least one of the attachment surfaces, the fixation element being rotatable between a stowed position, wherein the fixation element does not substantially protrude from the at least one of the attachment surfaces, and a deployed position, wherein the fixation element does substantially protrude from the at least one of the attachment surfaces for entering and being fixed to the spinal structure.
