    摘要： A hand-held instrument, with a rotary power input to a camshaft, has cam and follower arrangement to provide a reciprocating shaft output. A cutter is provided on the output shaft. In one example, rotating cam percussion is transmitted to the cutter by engaging the cutter with the tissue to be cut, and pushing the instrument forward toward the cutter. In another example, rotating cam percussion is transmitted to the cutter by engaging the cutter with the tissue to be cut, and pulling the instrument back toward the user while maintaining engagement of the cutter with the tissue. In both examples, the cutter remains in idle condition until an axially directed load, forward in the one example, or backward on the other example, is placed on the cutter by moving the instrument forward or backward, respectively, while the camshaft is rotating. A distractor with frame is used to spread and maintain space between vertebral bodies, enabling entrance of the cutter.

    摘要： An anchorage component that can be installed within a spinal stabilization system is disclosed. The anchorage component can include a first lateral half formed with a first spinous process engagement window and a second lateral half formed with a second spinous process engagement window. The first lateral half and the second lateral half can be installed around a spinous process of a vertebra.

    摘要： A disc preparation system includes an oscillating rasp for preparation of vertebral endplates and a central reamer for reaming a pair of kidney-shaped grooves into the vertebral endplate. The oscillating rasp is powered by a rotary power source. A linkage assembly is coupled to the rotary power source to convert the rotary motion into a reciprocating motion. A pair of rasps plates, which are linked to the linkage assembly, linearly reciprocate in opposite directions in response to the reciprocating motion of the linkage assembly. In one form, the central reamer includes a pair of cutting elements that are coupled to the rotary power source in order to rotate in response to rotational movement from the rotary power source. In another form, the central reamer includes a single cutting element coupled to an angled reamer handle and a reamer guide.

    摘要： A plating system for stabilization of a bony segment includes a plate engageable to at least first and second bony elements. For spinal stabilization, the plate is attached at least to first and second vertebrae with at least one bone fastener in each vertebra. Retaining members are attachable to the plate to prevent the bone fasteners from backing out of the plate. One retaining member is a variable retaining member that allows the bone fasteners to toggle in the plate without interference. A second retaining member is a fixed retaining member that fixes the bone fasteners relative to the plate.

    摘要： Systems and methods for stabilizing the spine are provided. For stabilizing the L5-S1 junction, the system includes a plate that has a generally triangular shape with an upper node and a pair of lower nodes. The upper node has a hole through the plate to receive a screw for passage into the L5 vertebra. The lower nodes each include a hole through the plate to receive screws for passage into the S1 vertebra. The system further includes a plate having a retaining element for preventing backout of screws inserted through the plate. Instruments and methods for attaching the plate to the spinal column are also provided.
