  • Patent number: 9216098
    Abstract: A method and apparatus for making a size measurement within an intervertebral space by placing an expandable and contractible device into the intervertebral space, expanding the device, measuring a size characteristic of the space, contracting the device and then removing it. The measurement may be accomplished by an external x-ray or other imaging device imaging the expanded device in situ or by mechanically operated devices. An expansion and contraction mechanism such as fluid containing bladder or mechanically shifted members expands the device which later contracts in a controlled manner to the contracted size. An apparatus and method is provided for the measuring of the intervertebral space at a controlled distraction force. The apparatus includes an expandable device for providing a measurement within the intervertebral space and facilitating the measurement of the angulations of the lordotic curve of the intervertebral space.

  • Patent number: 8308767
    Abstract: A spinal stabilization system includes vertebral engagement members and an intermediate structure. The vertebral engagement members are configured to be disposed between a first vertebra and a second vertebra. The vertebral engagement members generally include seating surfaces for accommodating at least a portion of a laminar region of adjacent vertebra and are adjustable between an operable and inoperable configuration. The intermediate structure extends between the vertebral engagement members. The structural cooperation of the vertebral engagement members and the intermediate structure is such that the engagement members distract the adjacent vertebrae.

  • Patent number: 8262731
    Abstract: Artificial disc devices are disclosed that restore correct anatomical intervertebral spacing for damaged discs while maintaining a substantially normal range of biomechanical movement for the vertebrae between which they are implanted. The disc devices include center bearing and outer or annular bearing portions with the center bearing portion including generally axially extending locating surfaces which cooperate with the facing vertebral surfaces to resist migration. The outer bearing portion is for load bearing or load sharing with the center bearing portion and includes surfaces that extend radially toward the periphery of the vertebrae so that subsidence about the center bearing portion is minimized. Alternate forms of the disc devices include one with an axially enlarged center ball bearing having an annular ring bearing extending thereabout and another having upper and lower plate members with a central bumper member and a surrounding resilient annular member therebetween.

  • Patent number: 8172876
    Abstract: 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.

  • Patent number: 8172885
    Abstract: 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.

  • Patent number: 8163019
    Abstract: 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 general, the implant retention device blocks or obstructs at least a portion of an opening in the annular wall, thereby keeping the implant from exiting the nuclear space through the annular opening. In one form, the implant retention device comprises an expulsion prevention member positioned adjacent the nuclear implant and configured to transition between a compressed position and an expanded position. In another form, the implant retention device may comprise a mounting portion to be positioned adjacent one of the vertebral bodies, a blocking portion for at least partially obstructing the annular opening, and an end projection at a terminal end of the blocking portion to resist expulsion of the implant through the annular opening.
