    摘要： Instruments for inserting an artificial disc implant in a space between adjacent bony portions include upper and lower guide members separated by a spreader with an implant positioned forwardly of the spreader. The spreader is movable forwardly between the guide members with a drive member to position the implant in a space between the bony portions while engaging at least a portion of the implant with at least one vertebra. The spreader contacts the adjacent bony portions to facilitate withdrawal of the inserter instrument when the implant is positioned in the space and engaged with the at least one vertebra.

    摘要： An implant for insertion into a patient includes a superior surface disposed at a first end of the implant and an inferior surface disposed at a second, opposite end of the implant. The superior and inferior surfaces of the implant are constructed with curvatures that approximately match the morphology of vertebral endplates. The inferior surface and superior surface may include the same or different radii of curvature within the coronal and sagittal planes. The inferior surface and superior surface may be defined by spherical radii. The radius of the superior surface may be about 60 percent to 74 percent of the radius of the inferior surface.
