    摘要： Spinal spacers 20 are provided for fusion of a motion segment. The spacers include a load bearing member 21 having a wall 22 sized for engagement within a space between adjacent vertebrae to maintain the space and an effective amount of an osteogenic composition to stimulate osteoinduction. The osteogenic composition includes a substantially pure osteogenic factor in, a pharmaceutically acceptable carrier. In one embodiment the load bearing member includes a bone graft impregnated in an osteogenic composition. In another embodiment, the osteogenic composition 30 is packed within a chamber 25 defined in the graft. Any suitable configuration of a bone graft is contemplated, including bone dowels, D-shaped spacers and cortical rings. A spinal spacer 300 for engagement between vertebrae is also provided which includes a body 301 formed of a bone composition. The body 301 includes a first end 311, an opposite second 315 end, a superior face 335 defining a superior vertebral engaging surface 337 and an inferior face 338 defining an inferior vertebral engaging surface 340. At least one of the vertebral engaging surfaces defines a set of migration resistance grooves 350. Each of the grooves 350 includes a first face 355 defining an angle of no more than about 90 degrees relative to the engaging surface 340 and a second opposing sloped face 360. The first and second faces 355, 360 define an arcuate pocket 370 therebetween for trapping vertebral bone to resist migration of the spacer 300. In one embodiment, the grooves 350 are arranged in series in that all of the second faces 360 slope in the same direction.

    摘要： A method and instrumentation particularly adapted for disc space preparation from an anterior approach to the spine. In one aspect, an expandable template is provided having guides to guide a cutting device for bilateral formation of openings in the disc space. In another aspect, an improved guide member is provided for guiding a cutting tool. Still further, the invention provides an improved double barrel guide sleeve with a central distraction extension and lateral non-distracting extensions. Optionally, the guide sleeve includes windows and covers to selectively cover the windows. An improved reamer with an internal chamber and optional modular coupling is also provided. A depth stop is provided to selectively engage a tool shaft and a guide sleeve to control tool penetration into the disc space. A method of using the disclosed instruments is also provided.

    摘要： An intervertebral prosthetic joint including a first articular component adapted to engage a first vertebra and a second articular component adapted to engage a second vertebra The articular components include abutting convex and concave articular surfaces that cooperate to permit articulating motion between the articular components. At least one of the convex and concave articular surfaces includes at least one surface depression that is configured to facilitate removal of matter disposed between abutting portions of the articular surfaces. In one embodiment of the prosthetic joint, each of the articular components has a vertebral bearing surface and a flange extending therefrom that is configured to penetrate a corresponding one of the first and second vertebrae, with the flange defining at least one opening extending therethrough to permit bone through-growth.
