摘要:
A spinal implant adapted to be positioned within a disc space between adjacent vertebrae includes a first intradiscal element, a second intradiscal element, and a coupling mechanism. The first and second intradiscal elements include respective first and second outer surfaces adapted to be positioned adjacent an endplate of respective first and second adjacent vertebrae. The first and second intradiscal elements further include respective first and second medial surfaces that are opposite the respective first and second outer surfaces, where the second medial surface is adapted to generally face the first medial surface upon assembly of the first intradiscal element with the second intradiscal element. The coupling mechanism is associated with the first and second medial surfaces and is adapted to provide relative rotational movement between the first and second intradiscal elements in a plane generally parallel with the first and second medial surfaces.
