Abstract: A plating system includes bone portion engaging anchors coupled to a connecting plate in moveable relationship to vary the spacing between the anchoring points of the plating system to the bone portions. The plating system includes instrumentation and method for installation thereof. The plating system is capable of both passive and active dynamization and the ability to produce the former from the latter.

Abstract: An at least in part cylindrical threaded interbody spinal fusion implant having an expandable height.

Abstract: A spinal fusion implant for insertion between adjacent vertebral bodies has opposed upper and lower surfaces adapted to contact each of the adjacent vertebral bodies from within the disc space, a leading end for insertion between the adjacent vertebral bodies, and a trailing end opposite the leading end. The trailing end has an exterior surface and an outer perimeter with an upper edge and a lower edge adapted to be oriented toward the adjacent vertebral bodies, respectively, and a plurality of bone screw receiving holes. At least one of the bone screw receiving holes is adapted to only partially circumferentially surround a trailing end of a bone screw received therein. At least one of the bone screw receiving holes passes through the exterior surface and one of the edges so as to permit the trailing end of the bone screw to protrude beyond one of the edges.

Abstract: A push-in orthopedic implant having an expandable height.

Abstract: Apparatus and a method of inserting spinal implants is disclosed in which an intervertebral space is first distracted, a hollow sleeve having teeth at one end is then driven into the vertebrae adjacent that disc space. A drill is then passed through the hollow sleeve removing disc and bone in preparation for receiving the spinal implant which is then inserted through the sleeve.

Abstract: Orthopedic implants being at least in part radially expandable at one of the leading or trailing ends to expand both the height and at least a portion of the width of the implant, and instruments and methods for inserting the implants into an implantation space are disclosed.

Abstract: An interbody spinal implant for insertion at least in part into an implantation space formed across a disc space between adjacent vertebral bodies of a human spine and into at least a portion of the endplates of the vertebral bodies. The implant includes a body having a leading end for insertion first into the disc space and a trailing end opposite the leading end and opposite upper and lower surfaces adapted to be placed in contact with and to support the adjacent vertebral bodies; the upper and lower surfaces being arcuate. The implant also has an opening passing through the upper and lower surfaces for permitting for the growth of bone from adjacent vertebral body to adjacent vertebral body through the implant. The implant is manufactured from a composite of cortical bone and at least one bioresorbable material. The cortical bone and at least one bioresorbable material being combined to form a machinable material from which the implant is manufactured.

Abstract: An interbody spinal fusion implant adapted for placement at least in part across an intervertebral space formed across a disc space between two adjacent vertebral bodies and for penetrating engagement into each of those vertebral bodies, the implant having a trailing end adapted to sit upon and not protrude from the anterolateral peripheral rim of bone of the vertebral body.

Abstract: An anterior cervical plating system having moveable plate segments to vary the overall length of the plate, moveable to allow and/or cause intersegmental compression of vertebral bodies, and coupled together by a non-detachable fastener. The plating system includes locking elements, each locking element adapted to lock at least two bone screws to the plate, instrumentation, and method for installation thereof. The plating system is capable of both passive and active dynamization and the ability to produce the former from the latter.

Abstract: An anterior cervical plating system having moveable plate segments to vary the overall length of the plate, moveable to allow and/or cause intersegmental compression of vertebral bodies, and coupled together by a non-detachable fastener. The plating system includes locking elements for locking only one bone screw to the plate, instrumentation, and method for installation thereof. The plating system is capable of both passive and active dynamization and the ability to produce the former from the latter.

Abstract: A lordotic guard and method for guiding a bone removal device to form an implantation space in the human spine and, if desired, for inserting a spinal implant into the implantation space.

Abstract: An interbody spinal fusion implant for insertion across a disc space between adjacent vertebral bodies of a human spine has a body two top side and two bottom side junctions, with at least a pair of diagonally opposed junctions having a distance therebetween that does not significantly exceed the implant body height. The implant also includes one or more bone penetrating protrusions extending outwardly from at least the upper and lower walls of the implant. The implant is inserted on its side between adjacent vertebral bodies and then rotated 90 degrees into place. The protrusions penetrate the endplates upon rotation, thereby securing the implant within the spine. The implant has at least one passage therethrough from the upper wall to the lower wall to promote fusion through the implant. Because of the specialized opposed junctions overdistraction between the adjacent vertebral bodies is avoided when the implant is rotated from an initial insertion position to a final deployed position.

Abstract: An interbody spinal implant made of a material other than bone adapted for placement across an intervertebral space formed across the height of a disc space between two adjacent vertebral bodies. The implant has a leading end that includes at least a portion of an arc of a circle from side to side, and sides that are at least in part straight or a trailing end having a radius of curvature of another circle from side to side.

Abstract: Anatomically contoured anterior cervical plates with bone ingrowth surfaces, providing for intersegmental compressive preloading, and a rigid and locked interface to all of the bone screws, with those engaging the vertebrae deployed in highly convergent pairs. The bone screws have a tapered self-tapping leading end, an increasing root diameter with a generally constant outer diameter with a thread that is narrow and sharp throughout and an enlarged head portion capable of an interference fit to the receiving holes of the plate. Instrumentation consists of plate holders, a compression apparatus and a pilot hole forming device that interlocks with the plate. Methods for spinal compression and bone hole preparation are provided.

Abstract: An anterior cervical plating system includes vertebral body engaging anchors coupled to a connecting plate in moveable relationship to vary the spacing between the anchoring points of the plating system to the vertebral bodies and to allow and/or cause intersegmental compression of vertebral bodies. The plating system includes instrumentation and method for installation thereof. The plating system is capable of both passive and active dynamization and the ability to produce the former from the latter.

Abstract: The present invention is directed to a major long bone ring implant for insertion into an implantation space formed across a spinal disc between two adjacent vertebral bodies of the spine. The implantation space has a wall portion, lip, or ridge with a flat portion for abutting the leading end of the bone ring implant. The bone ring implant has a leading end and a trailing end connected by opposed sides. The leading end has a straight cut portion. The opposed sides have portions that are preferably straight and at a 90° angle to the straight cut portion of the leading end to produce straight portions that are outwardly facing. The bone ring implant may be machined from a single bone or manufactured from a composite of cortical fibers, filaments, or particles. The bone ring implant may be used in combination with lockable screws, and preferably screw locks each preferably made of cortical bone or of a bioresorbable material.
