Abstract
The present invention discloses an inter-vertebral and implantable disk substituting for a fibro cartilage and including first and second hard outer layers between which is sandwiched a softer inner cushioning layer. Each of the outer layers includes an exterior texturized pattern for promoting bone in-growth subsequent to implantation. Each of the outer layers may also include an exteriorly integrally formed and angled mounting portion including an interiorly positioned aperture. The mounting portions are adapted to being applied against reconditioned side exterior locations of first and second succeeding intervertebral bodies and mounted to the bodies with a screw or clip.
