摘要： Intervertebral spacers, tools for implanting intervertebral spacers and methods of promoting fusion bone growth in the space between adjacent vertebrae are provided. The spacers include an elongated body having a first end, a second end and an outer surface. Side walls connect the first and second ends. The elongated body also defines an interior cavity. The side wall defines an opening to the interior cavity in a side of the elongated body. At least one of the first and second ends has a discontinuity, such as a concave surface, for nesting with an adjacent spacer. The tools include spacer engaging means for engaging a spacer and occlusion means for blocking an opening defined in the spacer. In some embodiments, the occlusion means includes a plate extendible from the housing. In one specific embodiment the plate defines a groove which is disposed around a fastener attached to the housing so that the plate is slideable relative to the housing. The methods of promoting fusion bone growth include utilizing the inventive spacers described herein.

摘要： 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.

摘要： A bone preparation device for shaping endplates forming an intervertebral disc space between two adjacent vertebrae includes a cutter component and a cutter-positioner component. The cutter-positioner is arranged to limit the distal travel of the cutter component and to restrict the range of motion of the distal end of the cutter component. The bone preparation device also includes a rotational interface between the cutter component and the cutter-positioner component. The rotational interface is structurally arranged to permit the cutting blade to be rotated at the same time the cutter component is restricted in its range of motion.
