A guide and method of using the guide for positioning within a patient between vertebral members for contouring each of the members. The guide comprises a first section and a second section. A first edge is positioned along an edge of the first section, and a second edge is positioned along an edge of the second section. One or more elongated rods extend through the sections. One or both of the sections are movable along the rods to adjust a spacing between the first edge and the second edge. When positioned within the patient, the first edge is aligned along a first vertebral member and the second edge is aligned along a second vertebral manner. A manner of locking the sections is included for preventing the sections from moving relative to each other once the first and second edges are aligned within the patient.

A guide sleeve with longitudinally offset bone engaging portions is provided for engagement with anterior-posterior offset vertebral bodies. In one aspect of the invention the guide tube has fixed bone engaging portions in a predetermined offset position. In another form of the invention, the guide sleeve is composed of at least two moveably connected portions adapted to permit adjustment of the offset between the bone engaging portions. Further, a method is provided for using a guide sleeve with offset bone engaging portions.

In one embodiment of the invention, an anterior fixation system includes a plate defining a plurality of screw holes, a number of screws and a number of locking assemblies for fixing the screws to the plate. The system includes two bone screws a fixed angle screw and a variable angle screw, that are configured to extend through the same screw openings in the fixation plate. The surgeon can select either the fixed or variable angled screws to be implanted with a single plate and can place either type of screw into any of the screw holes along the plate. The fixation plate according to the invention can include several screw holes in various patterns that provide the surgeon with great flexibility in the placement of bone screws depending upon the spinal anatomy and pathology. The invention further contemplates a locking assembly to lock one or more bone screws within a respective screw hole. In one embodiment, the locking assembly includes a washer that is held to the plate by a staked locking screw. The washer includes an outer surface that overlaps one or more screw holes. The washer is initially loosely held to the plate by the locking screw so that various tools and bone screws can be passed through the screw holes. In one embodiment of the washer, the washer includes cut-outs corresponding to the screw holes, along with a notch and key configuration for setting the locking washer in its locked configuration.

A spinal stabilization system comprises an elongated stabilization device including a curved configuration along a longitudinal axis thereof. The elongated stabilization device includes a length and cross-section sized for positioning through a pathway formed from an opening in a lateral mass of a first vertebra and into the first vertebra, through the facet joint formed by adjacent articular surfaces of the first vertebra and an adjacent bony structure, and into the adjacent bony structure. Instruments can be provided to form the pathway and insert the stabilization device into the pathway.

A modular intervertebral prosthesis system includes first and second baseplates and an insert designed to mate to the baseplates. The baseplates include a mounting section and a intervertebral section extending away from the mounting section generally perpendicular thereto. The intervertebral section has at least one aperture passing therethrough. When installed, the insert is disposed between the intervertebral sections of the baseplates and faces the apertures. In this way, the insert is not insulated from the vertebral members, thereby allowing for osteoinduction, osteoconduction, and/or osteointegration, if desired. The insert may take the form of an articulating-type insert or a fusion-type insert, with the baseplates being operative with both types of inserts. After installation of the insert between the baseplates, the insert may be readily removed, at least initially.

A retention system for maintaining a screw to a vertebral plate. One or more screws extend through apertures within the vertebral plate. A cavity is positioned adjacent to and overlaps into the aperture. A ring is positioned within the cavity and held in position by a cap. The cap attaches to the plate to prevent removal of the ring. The ring is deflectable between a first shape to allow the screw to be inserted and removed from the aperture, and a second shape to prevent screw back-out from the aperture. A method of using the system is also included and comprises positioning the ring within a cavity in the plate, maintaining the position of the ring to the plate by attaching a cap, inserting a screw through the aperture and attaching the plate to a vertebral member, and positioning the ring over the screw head and preventing the screw from backing-out.
