摘要:
A flexible dampening intervertebral spacer (100) to replace a spinal disc comprising upper and lower plates (101,103), an articulation element (102) and optional intermediate members (804,805). The articulation element has a plurality of interposed, concentric ring shaped segments (202) separated by one or more spaces (201) and one or more bridging elements (203) connecting the interposed segments. A first portion of the articulation element, preferably an inner-most segment, is preferably fixedly connected to the upper plate while a second portion of the articulation element, preferably the outermost segment, is preferably connected to the lower plate to permit relative movement of the endplates by elastic deflection or flexing of the articulation element without opposed surfaces rubbing against each other.
