1. An intervertebral cage structure, comprising:
- a main body comprising a first surface and a second surface located opposite to the first surface;
a first plate disposed on the first surface of the main body;
a second plate disposed on the second surface of the main body; and
an opening formed at a center portion of the intervertebral cage structure and extending from the first plate to the second plate via the main body,wherein at least one of the first and second plates comprise a surface pattern comprising a first plurality of depressions having a first depth that are symmetrically distributed over the surface pattern, and at least one second depression having a second depth that is different that the first depth, the at least one second depression being asymmetrically distributed over the surface pattern.

Abstract
An intervertebral cage structure that comprises a main body having a first surface and a second surface located opposite to the first surface, a first plate disposed on the first surface of the main body, a second plate disposed on the second surface of the main body, and an opening formed at a center portion of the intervertebral cage structure and extending from the first plate to the second plate via the main body, wherein the first and second plates comprise a surface pattern comprising at least one of a symmetrical geometric pattern and an asymmetrical geometric pattern.

19. An intervertebral cage structure, comprising:
-
a main body having a surface; a plate disposed on the surface of the main body; and an opening formed in the intervertebral cage structure and extending from the surface and through the main body, wherein the intervertebral cage structure has a surface pattern that comprises a plurality of first depressions and a plurality of second depressions formed into a surface of the plate, the plurality of first depressions each including a pocket having an undercut at a lower portion thereof to retain blood, tissue, or bone graft and to promote bone growth, and the plurality of second depressions each having a pocket with generally smooth walls with no undercut therein. - View Dependent Claims (20)
