Abstract

A method and instrumentation particularly adapted for disc space preparation from an anterior approach to the spine. The invention provides an improved 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 adjacent the distal end due to the overlapping working channel portions and reduced thickness wall portions. 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. A method of using the disclosed instruments is also provided.
