Abstract
An artificial replacement disk configured to be positioned in between a superior vertebrae and an inferior vertebrae. The upper and lower surfaces match the surface morphologies of the corresponding vertebrae and may be textured to promote bone in-growth. The artificial replacement disk may comprise gripping structures to permit easy manipulation of the artificial replacement disk during surgical procedures.
Claims14
An artificial replacement disk, wherein
- an upper surface of the disk is configured to contact a superior vertebrae;
- the upper surface of the disk matches a first surface morphology of the superior vertebrae;
- a lower surface of the disk is configured to contact an inferior vertebrae;
- the lower surface of the disk matches a second surface morphology of the inferior vertebrae;
- the disk comprises a plurality of slots, the plurality of slots including at least a first set of slots to receive a gripping tool in a first position and a second set of slots to receive the gripping tool in a second position;
- and
- the plurality of slots are configured to receive at least a first-type gripping tool and a second-type gripping tool.

- a lower surface of the disk is configured to contact an inferior vertebrae;
- the lower surface of the disk matches a second surface morphology of the inferior vertebrae;
- the disk comprises a plurality of slots, the plurality of slots including at least a first set of slots to receive a gripping tool in a first position and a second set of slots to receive the gripping tool in a second position;
- and
- the plurality of slots are configured to receive at least a first-type gripping tool and a second-type gripping tool.
