    摘要： Methods and instrumentation particularly adapted for disc space preparation for insertion of implants from an anterior approach to the spine are provided. The instruments include a guide sleeve defining a channel having overlapping cylindrical working channel portions and lateral non-distracting extensions extending from reduced thickness wall portions. The guide sleeve has an overall reduced width configuration. A pair of distractors are provided. A first distractor includes a shaft and distal tip, each having convex walls. A second distractor includes a shaft and distal tip including a recessed area at least along the tip. The first distractor is at least partially received within the recessed area of the second distractor when the first and second distractors are in side-by-side relation and a reduced overall width of the distractors is obtained. Preferably, the first and second distractors are used with the guide sleeve. Methods using the disclosed instruments are also provided.

    摘要： A retaining mechanism for use in affixing a stratum to bone is disclosed. The retaining mechanism comprises a stratum and a retaining element. The stratum comprises a first surface, a second surface, and at least one hole extending between the first surface and the second surface, wherein the second surface is configured to engage at least a portion of the bone. The retaining element is configured to engage the stratum and configured to at least partially overlap the at least one hole such that the retaining element helps prevent inadvertent backing out of the fastener after the fastener has been fully inserted into the at least at least one hole of the stratum, wherein the retaining element is substantially rigid. Further, methods of implanting a spinal plate are disclosed.
