摘要： A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head, a two-piece interlocking coupling element which mounts about the curvate head, and a rod receiving cylindrical body member having a tapered socket into which both the screw and the interlocking coupling element are securely nested. The interlocking coupling element includes a socket portion which is slotted and tapered so that when it is radially compressed by being driven downwardly into the tapered socket in the cylindrical body it crush locks to the screw. The securing of the rod in the body member provides the necessary downward force onto the socket portion through a contact force on the top of the cap portion. Prior to the rod being inserted, therefore, the screw head remains polyaxially free with respect to the coupling element and the body. In a preferred embodiment, the cap portion and the socket portion are formed and coupled in such a way that when the cap portion is compressed toward the socket portion, there is an additional inward radial force applied by the cap portion to the socket portion, thereby enhancing the total locking force onto the head of the screw.

摘要： A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head, a cross bar mounting element having a socket into which the head of the screw is initially polyaxially nested. The cross bar mounting element further includes a vertical split which permits the socket to be expanded or compressed via the application of a corresponding force directed at the split. The cross bar mounting element further includes a pair of upwardly extending members which define a trough into which a cross bar element is positioned. The cross bar element includes features which permit the secure fixation of a rod thereto, as well as a selectively slideable element, such as a nut, which may be tightened to apply the compressive force necessary to compress the interior volume onto the head of the screw, thus locking the assembly in place.

摘要： A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate ball top, a polyaxial head member having a socket into which the head of the screw is initially polyaxially nested, a vertical slot which renders the socket compressible, and a horizontal through hole having a tapered portion on one side of the vertical slot. A rod gripping cross-bar member, which is mounted through the through hole includes an axial split which permits the first end thereof to grip a rod, and then to be clamped onto the rod when the axial slot is narrowed. A nut is provided on the end of the cross-bar member which extend out from the through hole on the opposite end from the rod gripping mechanism. The advancement of the nut causes the cross-bar member to be compressed by the taper of the front portion of the through hole, thereby locking the rod in the gripping end thereof, and further provides the compression force necessary to compression lock the interior socket of the head against the ball top of the screw.

摘要： A hook device for use with support rod implantation apparatus is disclosed which is positionable along the central axis of the posterior surface of the spine and has independently rotationally positionable blade and head portions. The head portion is engageable with a deflecting top cylindrical portion which sits above the lamina. The insertion, and subsequent locking of a rod in the rod receiving channel of the head portion causes the blade portion and the head portions to be compression locked together by virtue of an interference fit.

摘要： The present invention is a polyaxial locking screw plate assembly for immobilization of vertebral bones, via fixation to surfaces thereof. The assembly includes a plate, having an upper portion and a lower portion, each of which has a pair of tapered holes, into which holes coupling elements and bone screws may be inserted. The upper part of the holes further includes an annularly recessed channel in which a snap-ring is disposed. The coupling elements each have an axial taper which matches the taper of the holes, and an interior semi-spherical concave surface in which the semi-spherical head of a bone screw may be polyaxially mounted. The bone screws are inserted through the holes until the coupling element engages and expands the snap-ring. Once the coupling element is fully seated in the hole, thereby locking the screw in place and the coupling element in the hole, the snap-ring contracts to its undeflected position and prevents the coupling element and screw from backing out of the hole in the event of loosening.

摘要： A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a head, a tubular body having holes in the top, side and bottom thereof, and a rod coupling element. The head of the screw is disposed in the body with the shaft of the screw extending out the bottom hole, such that the body and the screw may initially rotate relative to one another. The rod coupling element has a ball shaped end which seats in the body with the remainder of the rod coupling element extending out of the side hole of the body, such that the rod coupling element and the body are initially polyaxially coupled relative to one another. The ball end of the rod coupling element is disposed on top of the head of the screw. A set screw is provided in the top of the body, the tightening of which causes the ball, head, and body to be crush locked together, thereby preventing further relative motion.

摘要： A compression locking variable length cross-link device having modular components, including rod and/or pedicle screw coupling elements each having a hole which may be disposed co-linearly with respect to other such holes in opposing elements such that a threaded hinge-post may be inserted therein. A nut is utilized to compress the elements together to rigidly secure the elements once they have been properly positioned relative to one another. In an additional set of embodiments, a linkage member having an elongate hole therein may be used to couple similar elements thereto in a similar flexible hinge-post manner such that the elements may be coupled to the linkage member instead of to the opposing elements directly.
