Claim Text:
1. A unitary implant adapted for placement between adjacent surfaces of a joint comprising: an inflexible interbody device having no moving components; a first generally spherical articular bearing surface centered about a central axis and generally conforming to a geometry of a first adjacent joint surface; and a second generally spherical bearing surface centered about a central axis and generally conforming to a geometry of a second adjacent joint surface; an outer radial edge surface; a first protrusion extending from the first bearing surface about the central axis of the interbody device, wherein the first protrusion is configured to contact and puncture a central portion of the first adjacent joint surface endplate when the implant is positioned between vertebrae, and wherein the first protrusion and generally spherical articular bearing surface is adapted to allow rotation and restore near-normal motion between the interbody device and the first adjacent surface.
