摘要： A unitary locking cap mechanism, which is used with pedicle screws and other orthopaedic implant devices which couple bones to rods, includes rim and post portions which are rotationally freely coupled to one another to permit independent motion relative to one another. The rim element has a cylindrical body with an open end and a closed end; the closed end alternatively having a concentric hole defined by an inwardly directed flange. In one embodiment, the flange includes a series of slots, dividing into a plurality of wedge-shaped pie sections. In another embodiment, the sidewall of the cylindrical portion of the rim includes an annular recess. The post is a cylindrical shaft having surface elements at one end which provide for mutual engagement with the rim. These surface elements may be deflecting arms which seat into the annular recess of the rim, or an annular recess in the shaft into which the wedge-shaped pie sections of the flange portion may be resiliently snapped into. In an alternative embodiment, the shaft and the rim are coupled together through the concentric hole by a retaining ring which is placed around the shaft, in an annular recess therein, after the insertion of the shaft through the hole. Each embodiment are alternatively designed such that the post or the inner surface of the rim portions are threaded so that it can mate with a threading on the inner or outer upwardly extending, U-shaped channel forming, members of the heads of the pedicle screws.

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 hook device for use with support rod implantation apparatus, having a rod receiving body polyaxially mounted to a blade portion such that the body may be polyaxially manuevered relative to the blade, for easy rod coupling. The blade portion has a semi-spherical head portion which sits above the lamina. The rod receiving portion is a separate coupling element having lower and upper portions. The lower portion is slotted and tapered, and has a semi-spherical interior chamber in which the semi-spherical head is initially polyaxially disposed. The upper portion has a pair of upwardly extending members, defining therebetween a channel for receiving the rod. The uppermost parts of the upwardly extending members include an threading for receiving a top locking nut. A locking ring is disposed about the coupling element, substantially below the side recess; the top of the coupling element being initially positioned above the lower ledge of the side recess such that the rod, when initially disposed therein, seats against the top surface of the locking ring. When the rod is in place, the top locking nut is tightened to provides a downward force onto the rod. The rod, in turn, applies a force against the locking ring to descend down the tapered lower portion, therein locking the semi-spherical head in the interior chamber of the coupling element, and locking it into position relative to the blade portion. In an alternative variation, a rod retaining sleeve may be provided between the locking ring and the nut.

摘要： The present invention is an acetabular cup having at least one polyaxial locking screw for anchoring the cup in the desired bone site. The assembly includes an acetabular cup having at least one through hole having both threaded and tapered portions, into which holes a two-piece interlocking coupling element and a bone screw having a semi-spherical head may be inserted. The two-piece coupling element, including slideably joined socket and cap portions, is mounted about the semi-spherical head of the bone screw, which is inserted into the through hole and into the bone. The head of the screw is polyaxially mounted in the socket portions and as such may be inserted into the bone at a variety of angles. The socket portion of the coupling element has slots which permits crush locking of the head of the screw once the socket seats and is forceably driven into the tapered portion of the hole. The cap portion is threaded so is may be advanced into the inner portion of the hole, thereby further locking the coupling element into the hole, and applying an additional driving force against the socket portion to crush lock the screw head at the selected angle relative to the cup.

摘要： 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.

摘要： A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head, a locking collar disposed therearound, and a coupling element having a tapered socket into which both the screw and the collar are securely nested. The locking collar is slotted and tapered, and has a semi-spherical interior volume into which the screw head is initially polyaxially held. The coupling element has an axial bore through which the screw and locking collar may be inserted, and a tapered bottom which provides a radially inward force on the locking collar when forces thereinto. This radially inward force causes the locking collar to crush lock against the head of the screw, therein locking the two at the instant angulation. In an initial disposition, however, the screw head remains polyaxially free with respect to the locking collar, and with the coupling element. The coupling element includes a transverse channel in which a rod may be disposed. In a first embodiment the channel is formed between a pair of upwardly extending members, and in a second embodiment, the channel is formed in the side of the element. In either case, a rod which is inserted in the channel, seats against the top of the locking ring.

摘要： A variable length cross-link device for use with orthopaedic dual rod apparatuses includes a pair of elongate elements, each having a first end which mates with a rod or pedicle screw. The first element has a second end which is narrow and extending. The second element has a second end which is wide and extending, and includes a through hole. The invention further includes a post having an upper threaded portion mounted through the hole in the second element, and a passageway in the lower portion for receiving the second end of the first element. A nut is provided onto the post. Prior to tightening of the nut, the first element is slidable relative to the post and the second element, and the post element has rotational freedom within the through hole such that the first and second elements may be angulated relative to one another. Once the nut is tightened, the first and second elements are compressibly engaged, thereby crush locking the elements together. In a first embodiment, the first ends of the elongate elements are curvate and have set screw hole to hook and lock onto the rods. In a second embodiment the first ends have eyeloops for coupling to the heads of pedicle screws. In a third embodiment, which is compatible with either of the first end configurations, the narrow and extending end of the first element is cylindrical so that the first and second ends may axially rotate relative to one another.
