    摘要： Methods and instrumentation for surgical procedures relating to preparation of vertebral bodies and a disc space for insertion of spinal implants is disclosed. One instrument is a shim having a blade and a shaft having a first end connected with the blade. The blade is inserted into a distracted disc space to maintain distraction during subsequent procedures. Another instrument is a driver for driving the blade of the shim into the distracted disc space. Various methods contemplate the use of these instruments to maintain disc space distraction during disc space preparation for receiving an implant.

    摘要： An intervertebral disc augmentation implant for implantation between a pair of vertebral bodies comprises an elastically deformable outer casing having at least one thickness dimension and a core member having isotropic material properties. The core member is entirely encased within the outer casing and has a height dimension along an axis defined by the pair of vertebral bodies. The modulus of elasticity of the core member is greater than a modulus of elasticity of the outer casing, and the height dimension of the core member is greater than the at least one thickness dimension of the outer casing.

    摘要： A vertebral implant for impaction in a disc space to restore and/or maintain desired disc space height and spinal orientation is provided. The implant has an elongated basis body having a generally lens-shape provided by convex upper and lower surfaces. Bearing surfaces are provided on the cross-edge surfaces of the endwalls. Grooves are provided in the upper and lower surfaces positioned between the bearing surfaces. The implant can be prepared from a wide variety of materials including metallic materials, synthetic materials, polymeric materials, ceramic materials, and composite materials including reinforced materials i.e. glass, fiber, and/or carbon fiber reinforced materials (CFRP).

    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.
