Patent number: 8876687Abstract: Retractor for insertion in an incision of a patient includes a frame defining a central opening and a reference plane, and at least one blade disposed within the central opening. The blade operatively coupled to the frame by a support structure for movement in a first direction generally laterally with the reference plane between an unretracted position and a retracted position, a second direction at an angle extending through and relative to the reference plane for adjustment of the blade depth, and a third direction rotationally relative to the reference plane. Additionally, the frame includes a track in mating relationship with the support structure for sliding movement therebetween in a defined relationship relative to the reference plane. Retractor assembly includes the retractor as previously described, in combination with an adjustment tool or an insertion tool.Type: GrantFiled: March 7, 2007Date of Patent: November 4, 2014Assignee: Zimmer Spine, Inc.Inventors: Robert J.

Patent number: 8795373Abstract: A method and apparatus is provided for use in spinal fusion procedures. A one or two piece interbody fusion device has a fusion bearing component designed to bear the axial loading from the end plates of adjacent vertebrae. An optional retention piece prevents migration of the load bearing device. One or more fasteners secure the retention device to the vertebrae above and below the load bearing device. The fasteners cause the end plates of the vertebrae to compress the end plates to the load bearing device to facilitate proper fusion. An anti-backout mechanism prevents the fasteners backing out.Type: GrantFiled: January 23, 2008Date of Patent: August 5, 2014Assignee: SpineSmith Partners, L.P.Inventors: Robert J. Jones, Mark Rahm, Kevin Dunworth

Publication number: 20140135855Abstract: A spinal stabilization system may be formed in a patient. In some embodiments, a minimally invasive procedure may be used to form a spinal stabilization system in a patient. Bone fastener assemblies may be coupled to vertebrae. Each bone fastener assembly may include a bone fastener and a collar. Extenders may be coupled to the collar to allow for formation of the spinal stabilization system through a small skin incision. The extenders may allow for alignment of the collars to facilitate insertion of an elongated member in the collars. An elongated member may be positioned in the collars and a closure member may be used to secure the elongated member to the collars. An adjuster may be used in conjunction with the extenders to change a separation distance between the bone fastener assemblies.Type: ApplicationFiled: January 27, 2014Publication date: May 15, 2014Applicant: Zimmer Spine, Inc.Inventors: Robert J.

Patent number: 8226689Abstract: A spinal implant provides support for desired parts of the spine. The implant can provide support in fusion situations. The spinal implant includes a pair of longitudinal rods and a transverse rod. A pair of variable cross-link devices couple the transverse rod, respectively, to the first and second longitudinal rods. Each variable cross-link device includes a body, having a curved member, a plug, and a rod engaging member. Fastening the plug into the body of the respective variable cross-link device causes application of force that couples the plug and the rod engaging member to the respective longitudinal rod. Fastening the plug also causes application of force that couples the rod engaging member to the transverse rod. Furthermore, fastening the plug causes application of force that couples the respective longitudinal rod to couple to the variable cross-link device. The surgical procedure may use minimally invasive surgery or non-minimally invasive surgery, as desired.Type: GrantFiled: September 23, 2005Date of Patent: July 24, 2012Assignee: Zimmer Spine, Inc.Inventors: Robert J.

Patent number: 8062338Abstract: An adjustable transverse connector connects orthopedic stabilization rods that may be parallel or skewed in orientation relative to each other The connector may include two sections that are joined together by a fastener. The connector may be adjustable in many ways. The overall length of the connector may be adjustable. The rod openings of the connector may be partially rotatable about a longitudinal axis of the connector. The two sections of the connector may be angulated. The connector may include cam locks that securely attach the connector to the rods. Rotating a cam lock may extend a rod engager into a rod opening. The rod engager may be a portion of the cam lock. The extension of the rod engager into a rod opening may push a rod against a body of the transverse connector to form a frictional engagement between the connector, the rod, and the rod engager.Type: GrantFiled: February 2, 2009Date of Patent: November 22, 2011Assignee: Zimmer Spine, Inc.Inventors: G.

Publication number: 20110282394Abstract: Embodiments disclosed herein provide a plating system including a bone plate, a bone screw and a ring. The bone screw preferably connects the bone plate to a bone, and the ring preferably fixes the bone screw into a borehole of the bone plate such that the bone screw extends from the bone plate at a selected angle. The ring is preferably capable of swiveling within the borehole to allow the bone screw to be angulated at a plurality of angles oblique to the plate. The bone screw may have a head having a tapered, threaded surface for engaging the ring. The ring preferably has threading on its inner surface for mating with the threading on the head. The inner surface of the ring may be tapered. Movement of the head through the ring preferably expands the ring against the bone plate to fix the bone screw at a selected angle relative to the bone plate.Type: ApplicationFiled: July 25, 2011Publication date: November 17, 2011Inventors: Erik J.
