    Abstract: A hook and rod apparatus for implantation and fixation to the centerline of the spine, wherein the rod provides for immobilization of the spine via its inherent rigidity. The hook elements are designed to be mounted at the arched portion of the lamina. In a first plow shaped variation, the blade portion of the hook is an arched surface which seats under the arched surface of the lamina. In a second claw shaped variation, the blade portion includes a bifurcated conformation having a pair of offset flat extending members which are offset so as to seat under the angled portions of the lamina which are directly laterally disposed relative to the arched center of the lamina. The rod coupling features of the hooks may further be polyaxial by virtue of separate coupling elements which may be mounted to the blade portion, for example on a semi-spherical head portion thereof. In the alternative, the blade portion may have a contractible recess formed in a top thereof, for receiving and locking to a shaft of body portion at a variety of heights. The rod receiving features of the hook may include both the polyaxial and height variability natures of both of the previous hooks by having a shaft portion which has a semi-spherical head onto which the coupling element is mounted.

    Abstract: A compression locking variable length cross-link device having a pair of rod hooking elements, each having rod securing and flat coupling ends. The flat coupling ends are slidably coupled to one another for selective locking to one another independent of the relative separation of the rod securing ends. Each hooking element has a curvate end formed from flat material which has been shaped into a hook conformation to cup the lateral outside surface of a corresponding rod. A set screw positioned through a hole in the top of the curved end locks the curvate end to the rod. In a first embodiment, one (a first) rod hooking element has a narrow flat end having a knurled top surface. The corresponding flat end of the other (second) element is wider, has a knurled undersurface, and has a hole therethrough for receiving a post. The post has a transverse passageway through it for slidably receiving the narrow flat portion of the first element, and an upper portion which is threaded. The threaded upper portion is positioned in the hole of the flat end of the second element. Tightening of a top locking nut causes the two knurled portions of the flat ends to compression lock together. In a second embodiment, the undersurface of the flat end of first element is knurled. The second element has a thickened corresponding end, having a flat passageway through it for slidably receiving the flat end of the first element. A set screw may then be engaged through a hole in the top of the thickened portion to compress and lock the two together.

    Abstract: The present invention is a polyaxial locking screw plate assembly for immobilization of vertebral bones, via fixation to surfaces thereof. The invention includes a plate, having an upper portion and a lower portion, each of which has a pair of holes having a threaded upper portion and a tapered lower portion. Coupling elements, including slideably joined socket and cap portions, are mounted about the semi-spherical heads of bone screws, which are screwed through the holes in the plate and into the bone. The heads of the screws are polyaxially mounted in the socket portions and as such may be inserted into the bone at a variety of angles. The socket portions of the coupling elements have slots in them which permit crush locking of the heads of the screws once the sockets seat and are forceably driven into the tapered portions of the corresponding holes. The cap portions are threaded so they may be advanced into the upper portions of the corresponding holes, thereby further locking the coupling elements into the holes, and applying an additional driving force against the corresponding socket portions to crush lock the screw heads at the selected angle relative to the plate.

    Abstract: A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head and a coupling element. The coupling element has a tapered lower portion including a slotted interior chamber in which the curvate head is initially polyaxially disposed. The coupling element further includes a recess formed in its side for receiving a rod of an implant apparatus, and an exterior threading disposed on its upper portion onto which a locking nut may be downwardly translated. A hollow cylindrical rod securing sleeve fits above the rod receiving recess, having a pair of grooves formed in its lower surface for seating against the rod. A locking collar is disposed below the rod receiving recess, having a pair of grooves in its top surface for receiving thereon the rod. Both the sleeve and the collar are axially translatable along the exterior surface of the coupling element. The downward translation of the collar provides an inward force on the outwardly tapered portion upon downward translation thereof, thereby causing the vertical slots to close, and crush locking the screw head within the interior chamber. The downward translation of the locking nut locks the rod between the sleeve and the collar, and the screw in the interior chamber.

    Abstract: A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head and a coupling element. The coupling element has a tapered lower portion including a slotted interior chamber in which the curvate head is initially polyaxially disposed; a recess formed in its side for receiving the rod of the implant apparatus; and an exterior threading disposed on its upper portion for receving thereon a top locking nut. A locking ring is disposed about the exterior of the lower portion of the coupling element, and provides an inward force on the outwardly tapered portion upon downward translation thereof, thereby causing the interior chamber to crush lock the screw head therein, thus eliminating the polyaxial nature of the screw-element coupling. In addition, a hollow cylindrical rod securing sleeve fits over the coupling element and locks the rod to the coupling element. In a first embodiment, the locking nut seats against the top of the sleeve, which seats against the top of the locking ring, and causes the sleeve to lock the rod and the screw in the interior chamber. In a second embodiment, the locking ring and the bottom of the coupling element have threads so that the locking ring may be translated separately to lock the screw.
