ABSTRACT:
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.
