    摘要： A disc preparation system includes an oscillating rasp (26) for preparation of vertebral endplates and a central reamer (100) for reaming a pair of kidney-shaped grooves into the vertebral endplate. The oscillating rasp (26) is powered by a rotary power source. A linkage assembly (42) is coupled to the rotary power source to convert the rotary motion into a reciprocating motion. A pair of rasps plates (66, 68), 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 (100) includes a pair of cutting elements (104) 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： Systems and methods for stabilizing the spine are provided. For stabilizing the L5-S1 junction, the system includes a plate (7) that has a generally triangular shape with an upper node (8a) and a pair of lower nodes (9a, 10a). The upper node (8a) has a hole (8) through the plate (7) to receive a screw (11) for passage into the L5 vertebra. The lower nodes (9a, 10a) each include a hole (9,10) through the plate (7) to receive screws (12, 13) for passage into the S1 vertebra. The system further includes a plate (7) having a retaining element (32) for preventing backout of screws inserted through the plate (9). Instruments and methods for attaching the plate to the spinal column are also provided.
