Abstract: A sacral reconstruction fixation device aids in stabilizing the pelvis and the lumbar spine after a sacrectomy in cooperation with a spinal rod and transiliac rod. A pair of the fixation devices may be secured to respective ilia and respective spinal rods. The transiliac rod may be secured to both of the fixation devices. The fixation devices include first and second parts that are initially relatively rotatable about a common axis to aid in connecting the fixation devices to the spinal rod and transiliac rod. The body part is intended to be mated to the spinal rod, while the second part is intended to be mated to the transiliac rod. The fixation device's parts are subsequently locked against rotation and against longitudinal translation, advantageously both relative to each other and the rods.

Abstract: A sacral prosthesis for a partial or complete sacrectomy has a central body with a platform on a superior face thereof; first and second arms extending superiorly and laterally from the central body, with the arms including respective terminal portions for anchoring to a respective ilium. The terminal portions are held spaced from one another and the central body is suspended by the arms such that the platform is disposed inferiorly to the terminal portions at a fixed position relative thereto. The sacral prosthesis supports a spinal column against inferior displacement by supporting a vertebral body with the platform, while advantageously simultaneously preventing relative lateral displacement of the ilia. The sacral prosthesis may advantageously be formed of a radiolucent material.

Abstract: The present application is directed to vertebral implant systems and methods of using the systems. In one embodiment, the vertebral implant system includes first and second implants each including opposing end plates that are independently adjustable to form an included angle. Each implant within the system may include a different included angle to fit within a different sized and/or shaped vertebral space. Tool engaging features may be positioned on each end plate. The features on the opposing end plates may be substantially parallel when the implant is oriented at its specific included angle. The parallel orientation provides for accurate positioning of the implant within the vertebral space and may also assist in attaching and detaching the implant from the insertion tool. Using the system may include determining an anatomical angle of the vertebral space. Once the angle is determined, one of the implants from the system is selected that best matches the anatomical angle.

Abstract: A vertebral implant for insertion into a patient includes an insert formed from an osteoconductive material and further including a biocompatible polymer body that is formed into the insert. The insert may extend over part or substantially the entire bone contact surface of the implant. The insert includes a bone contact surface and a substrate interface. The implant may include fibers that extend across the substrate interface from the insert to the body. The insert may be thin relative to the overall thickness of the implant. The insert may be preformed. The insert may be formed using a molding process. The body may be molded onto the insert.

Abstract: A spinal plate including a plate portion having an upper side and an opposite lower side, a connector portion that is integrally attached to the upper side of the plate portion and defining a channel sized to receive an elongate rod therein, and at least one bone engagement member extending from the lower side of the plate portion and adapted for engagement with bone. In one embodiment, the connector portion is formed integral with the plate portion so as to define a unitary, single-piece structure. In another embodiment, the bone engagement member comprises one or more prongs formed integral with the plate portion and/or one or more bone screws extending through corresponding openings in the plate portion. In certain embodiments, the spinal plate includes a pair of connector portions integrally attached to the upper side of the plate portion and defining channels, each sized to receive an elongate rod therein.
