A61F 2/44

US Classification:

623 1711

Abstract:

An intervertebral stabilizer includes: a first member operable to engage an endplate of a vertebral bone of a spine, the first member having top and bottom surfaces defining a thickness therebetween; a second member spaced apart from the first member and operable to engage an endplate of an adjacent vertebral bone of the spine; a connecting element located substantially between and connecting the first and second members; and the first member having at least one slot extending through a portion thereof through its entire thickness and top and bottom surfaces, creating first and second portions of the first member, wherein the slot imparts compressibility and/or expandability to the intervertebral disc replacement device.
