摘要： A spinal fixation system is provided that includes a coupling member and a locking device that is operable to fix an elongate member relative to the coupling member. In one form, locking device includes opposing lock arms operable to retain the locking device relative to the coupling member in an initial position prior to the locking device fixing the elongate member relative to the coupling member. In another form, the coupling member and locking device include cooperating structure therebetween in the form of a protrusion and a guide track, the cooperating structure arranged and configured to retain the locking device within an internal space of the coupling member. There is also provided a retainer operable to minimize pivoting of the coupling member relative to an anchor member and to substantially retain an anchor member depressed within an internal space of the coupling member to minimize play therebetween.

摘要： A spinal fixation system is provided that, in one form, includes a coupling member having a cam lock member that is fixed against translation therealong as it is turned with turning of the cam lock member causing an elongate member such as a spinal rod to be pushed downward in the coupling member for fixing the rod therein. In another aspect, the rod is fixed against a low profile insert that seats in a recess formed in the head of an anchor member projecting from the coupling member. The insert has an upper surface against which the rod is fixed and that in one form is flat to provide for line contact against the rod so as to minimize damage thereto. In another form, the cam lock member cams against a clamping member driving it downward in the coupling member for fixing the rod therein.

摘要： A spinal stabilization system includes a first engagement member and a support structure. The first engagement member is adapted to be disposed between a first vertebra and a second vertebra. The engagement member generally includes a seating surface for accommodating at least a portion of a laminar region of the first vertebra. The support structure engages a portion of the second vertebra. The structural cooperation of the first engagement member and the support structure is such that the engagement member restricts reduction of the intervertebral spacing between the first and second vertebrae.

摘要： A crosslink member for securing spinal rods is disclosed having connector ends that include a brace and a locking member, each having an arcuate face resting on and securing a spinal rod. The locking member is secured by a cam member that rotates relative to the locking member and that cams against the connector to displace the cam member. The crosslink includes a male connector with a cylindrical cross rod received by a cavity in a female connector. The cross rod is secured by a pivotable clamp device in the female connector, and the cross rod connector and female connector may pivot, rotate, and telescope relative to each other. To reduce size without sacrificing pivot sweep, the cross rod has beveled edges, and the cavity of the female connector has windows to provide pivot clearance.

摘要： Invertebral implants are provided for carrying bone graft material and extruding the bone graft material between the implant and the adjacent vertebral bodies. The implants include first and second implant extrusion members shiftable relative to one another between a pre-implantation configuration having an enlarged cavity for receiving bone graft material therein and an implantation configuration having a smaller cavity. As the first and second implant extrusion members shift during implantation to the implantation configuration bone graft material is extruded from the cavity and into gaps or spaces between the upper and lower vertebral engaging surfaces of the implant and the adjacent vertebral bodies. After extrusion the bone graft material is subjected to spinal loading and stress to encourage strong bone growth therethrough.

摘要： An implant retention device is provided to assist in restraining movement of a nuclear implant and to assist in preventing expulsion of the nuclear implant through an incision portal or defect in the annular wall. In one form, the implant retention device comprises an expulsion prevention member associated with the nuclear implant and is configured to transition between an unexpanded position and an expanded position. In another form, a method for restraining a nuclear implant includes cutting an opening in the annulus, shifting an implant retention device into an unexpanded position, inserting the implant retention device through the opening, and shifting the retention device to an expanded position.

摘要： Bone plate and bone screw lock systems are provided for use in surgical implants. In a preferred form, the bone plate or other implantable member defines a bore for receiving a bone screw and a recess in communication with the bore. A screw lock operates in the bore at the recess to engage and lock the bone screw against unintentional movement. The preferred screw lock is shifted about the screw between an unlocked position to allow manipulation of the screw and a locked position in which the screw lock grips the head of the screw to prevent movement of the screw. The screw lock preferably has a c-shaped collar configuration with opposing ends and a camming engagement with the plate or other member in the recess. Upon rotation of the screw lock, the camming engagement causes the ends of the collar to either shift toward one another in which the collar compresses about the screw to lock the screw or away from another to unlock the screw head.
