    摘要： An intervertebral disc prosthesis comprises a left prosthesis component and a symmetric right prosthesis component positioned in an intervertebral space. Each prosthesis component includes a superior vertebra facing surface, an inferior vertebra facing surface, and a substantially spherical bearing surface. The bearing surface is positioned between the superior vertebra facing surface and the inferior vertebra facing surface. The superior vertebra facing surface is provided on a superior endplate and the inferior vertebra facing surface is provided on an inferior endplate. The superior endplate is operable to rotate relative to the inferior endplate upon the bearing surface. Each prosthesis component further comprises an elastic member positioned between an endplate and the bearing surface. The elastic member may be substantially cylindrical with a plurality of resilient ribs. Flexion/extension, lateral bending, and torsional movement are allowed by a combination of endplate rotation upon the bearing surface and compression of the elastic member.

    摘要： An implant for assisting in providing a correct separation distance between overlapping superior and inferior articular processes, such as associated with succeeding lumbar vertebrae (L1-L5). The implant teaches a pocket defining body having an open rim profile of variable wall thickness, the implants being employed individually or in paired fashion between each laterally spaced pair of overlapping facet contact locations established between inwardly facing superior articular process facets associated with a first (lower) vertebra and opposing outwardly facing inferior articular process facets associated with a second (upper succeeding) vertebra. Use of the implant assists in providing correct lateral spacing between the superior and inferior processes, reducing or preventing pinching of the laterally extending nerve branches of the spinal nerve column.
