Abstract: A bone fastener includes a proximal member having an inner surface that defines an implant cavity and an outer surface including a first threaded portion configured for penetrating fixation with tissue and a second portion. The proximal member defines a longitudinal axis. An intermediate member includes an inner surface extending between a proximal portion connected with the second portion and a distal portion. A distal member includes an outer surface extending between a proximal portion disposed with the distal portion of the intermediate member and a distal portion configured for penetrating fixation with tissue. The distal member is configured for axial translation relative to the intermediate member. Methods of use are disclosed.

Abstract: A spinal fixation device may include a bone anchoring member, a rod receiver, and an connection member. The rod receiver may include a channel for receiving a rod projection from a first adjacent fixation assembly. The rod receiver may have a central axis such that the channel is generally perpendicular to the central axis. The connection member may have a rod projection configured to extend to a second adjacent fixation assembly. The rod receiver may be coupled to the connection member and rotatable about the central axis of the rod receiver. The interior fixation assembly may be axially fixed such that the bone anchoring member, the rod receiver and the connection member are not translatably movable relative to each other.

Abstract: A method for treating a spine disorder includes providing a bone fastener including a distal portion and a proximal portion including an axial opening and defining a longitudinal passageway. At least one lateral opening is disposed in communication with the longitudinal passageway. The axial opening is disposed in communication with the longitudinal passageway. The distal portion is engaged with a first vertebral surface. The second vertebral surface is spaced apart from the first vertebral surface. A radiopaque biologic is introduced through the axial opening and into the longitudinal passageway and delivered to a surgical site adjacent the first vertebral surface and the second vertebral surface. Systems for treating a spine disorder are disclosed.

Abstract: A spinal implant includes two plates that are connected together by a post. The implant is configured for each plate to be positioned on outer lateral sides of spinous processes with the post extending through the interspinous space. One of the plates includes a channel that receives the post. The channel is configured so that the plate can be assembled over the post from a direction normal to the post's axis. This configuration allows the plate to be added in a posterior to anterior direction for the typical situation, without having to first locate the plate laterally outboard of the post's tip. As such, the spinal implant allows for a more compact surgical site to be used for the spinal implant implantation procedure.

Abstract: A guide and a blade for contouring vertebral bodies. The guide is sized to be mounted between two vertebral members and includes a pair of edges for receiving the blade. The pair of edges are spaced a distance apart for the first edge to align with a first vertebral member, and the second edge to align with a second vertebral member. The blade includes a pair of arms with at least one cutting edge. The arms are sized to fit within the pair of edges respectively. Using the blade and guide comprises inserting the guide adjacent to two vertebral members, and inserting the arms through the pair of edges to contour the ends of the members. In an embodiment with cutting edges at the distal ends of each of the arms, the two vertebral members can be contoured simultaneously.

Abstract: Embodiments for a spinal implant having elements that are accessible by a surgical approach and releasably engagable by a surgical tool for improved revision of the spinal implant about a patient's spine.

Abstract: A prosthetic device and method, according to which first end plate engages a first vertebral body, and a second end plate engages a second vertebral body. An insert lockingly engages one of the end plates and engages the other end plate in a manner to permit relative movement therebetween.

Abstract: 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.
