Patent number: 9610105Abstract: Embodiments of an orthopedic implant device and system, and methods for implanting them, are disclosed. The implant may include a receiver member having a channel for accommodating an elongated rod or other longitudinal member, a bone anchoring member such as a screw or hook, and a base member rotatable with respect to the receiver member for retaining the bone anchoring member in the receiver member. The base member is configured to allow at least two different degrees of maximum angulation of the bone anchoring member with respect to the receiver member. The number and relative direction of such angulations are independent of the orientation of the channel or other part of the receiving member.Type: GrantFiled: September 19, 2011Date of Patent: April 4, 2017Assignee: Warsaw Orthopedic, Inc.Inventors: Robert A. Farris, Jeffrey W. Poyner

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

Publication number: 20130345815Abstract: Spinal spacers for fusion of a motion segment. A spinal spacer includes a body, which may be formed of a bone composition. The body includes a first end, an opposite second end, a superior face defining a superior vertebral engaging surface and an inferior face defining an inferior vertebral engaging surface. At least one of the vertebral engaging surfaces defines a set of migration resistance grooves. Each of the grooves includes a first face defining an angle of no more than about 90 degrees relative to the engaging surface and a second opposing sloped face.Type: ApplicationFiled: August 22, 2013Publication date: December 26, 2013Applicant: Warsaw Orthopedic, Inc.Inventors: Eddie F. Ray, III, Lawrence M. Boyd, James E. Van Hoeck, Bradley J. Coates, Jeffrey W. Poyner

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. Farris, Kevin T. Foley, Stephen M. Papadopoulos, Jeffrey W. Poyner, Ricardo Sasso

Publication number: 20100057207Abstract: Spinal spacers 20 are provided for fusion of a motion segment. The spacers include a load bearing member 21 having a wall 22 sized for engagement within a space between adjacent vertebrae to maintain the space and an effective amount of an osteogenic composition to stimulate osteoinduction. The osteogenic composition includes a substantially pure osteogenic factor in, a pharmaceutically acceptable carrier. In one embodiment the load bearing member includes a bone graft impregnated in an osteogenic composition. In another embodiment, the osteogenic composition 30 is packed within a chamber 25 defined in the graft. Any suitable configuration of a bone graft is contemplated, including bone dowels, D-shaped spacers and cortical rings. A spinal spacer 300 for engagement between vertebrae is also provided which includes a body 301 formed of a bone composition.Type: ApplicationFiled: July 20, 2009Publication date: March 4, 2010Inventors: Eddie F.

Patent number: 7303563Abstract: A orthopedic fixation system comprising a plate with an outwardly-extending member. A saddle may be mounted on the member and includes spaced-apart arms that form a channel to receive a rod. An engagement member may be mounted within the saddle to prevent escape of the rod. In one embodiment, the engagement member is attached to the saddle to apply a downward force on the rod and an upward force on the saddle to lift the saddle relative to the plate. A method of attaching an orthopedic rod is also included. In one embodiment, a rod is positioned within a channel in the saddle and a downward force is applied against the anchor which results in an upward force on the saddle to lift the saddle relative to the anchor.Type: GrantFiled: June 17, 2004Date of Patent: December 4, 2007Assignee: SDGI Holdings, Inc.Inventors: Jeffrey W. Poyner, Robert A. Farris

Patent number: 7276081Abstract: A spinal spacer 300 for engagement between vertebrae is provided which includes a body 301 formed of a bone composition. The body 301 includes a first end 311, an opposite second 315 end, a superior face 335 defining a superior vertebral engaging surface 337 and an inferior face 338 defining an inferior vertebral engaging surface 340. At least one of the vertebral engaging surfaces defines a set of migration resistance grooves 350. Each of the grooves 350 includes a first face 355 defining an angle of no more than about 90 degrees relative to the engaging surface 340 and a second opposing sloped face 360. The first and second faces 355, 360 define an arcuate pocket 370 therebetween for trapping vertebral bone to resist migration of the spacer 300. In one embodiment, the grooves 350 are arranged in series in that all of the second faces 360 slope in the same direction.Type: GrantFiled: November 23, 1999Date of Patent: October 2, 2007Assignee: Warsaw Orthopedic, Inc.Inventors: Bradley J.

Publication number: 20030236472Abstract: Systems and methods for measuring a separation characteristic of separated anatomical elements include a separator contactable with first and second anatomical elements. A sensor provides an indication of the separation characteristic of the anatomical elements. The measured separation characteristic can be compared with a desired or predetermined separation characteristic, and subsequent surgical procedures can be performed based on the measured separation characteristic.Type: ApplicationFiled: September 30, 2002Publication date: December 25, 2003Inventors: James Van Hoeck, Bradley J.
