Publication number: 20140200617Abstract: A posterior fixation system includes a saddle member, an anchoring member, an occipital plate, an occipital rod, and a cross-link connector. The anchoring member anchors the saddle member to bone. The saddle member includes a channel that is adapted to receive an orthopedic rod. The saddle member and the anchoring member can be coupled so as to allow multi-axial movement of the members. Connection of individual rods can be accomplished by connecting the rods with the cross-link connector. The occipital plate secures the rods to the occipital bone of the skull. Alternatively, the occipital rod can be secured to the occipital bone.Type: ApplicationFiled: August 19, 2013Publication date: July 17, 2014Applicant: WARSAW ORTHOPEDIC, INC.Inventors: Robert A. Farris, Kevin T. Foley, Stephen M. Papadopoulos, Jeffrey W. Poyner, Ricardo Sasso

Patent number: 8512380Abstract: A posterior fixation system includes a saddle member, an anchoring member, an occipital plate, an occipital rod, and a cross-link connector. The anchoring member anchors the saddle member to bone. The saddle member includes a pair of upright portions that define a channel. The channel is adapted to receive an orthopedic rod, and the saddle member can include a hole to receive the anchoring member. The saddle member and the anchoring member can be coupled so as to allow multi-axial movement of the members. The anchoring member in one embodiment is a screw coupled to the hole of the saddle, and in another embodiment, the anchoring member is a hook. The offset member may be coupled to the saddle member to allow for offset connection of rods. Connection of individual rods can be accomplished by connecting the rods with the cross-link connector. The cross-link connector has an integrally formed cylindrical member that couples a pair of coupling portions together.Type: GrantFiled: March 1, 2010Date of Patent: August 20, 2013Assignee: Warsaw Orthopedic, Inc.Inventors: Robert A.

Patent number: 8277493Abstract: 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 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. Also contemplated is a locking assembly to lock one or more bone screws within a respective screw hole.Type: GrantFiled: January 11, 2006Date of Patent: October 2, 2012Assignee: Warsaw Orthopedic, Inc.Inventors: Robert A. Farris, Jeffrey Wade Poyner, Volker K. H. Sonntag, Regis W. Haid, Jr., Stephen M. Papadopoulos
