Implants for full constraint of pyramesh T-cage

A multi-level vertebral implant, comprising:

• a biocompatible cage;
• and
• a first endplate and a second endplate that each comprise:
• (i) a bone contacting surface that is inclined with respect to a supporting surface disposed opposite from the bone contacting surface;
• (ii) a plurality of anti-migration features extending from each bone contacting surface and being configured to contact an adjacent vertebrae, respectively;
• (iii) a cage holder extending away from each support surface, each cage holder comprising a hollow protrusion defining a fusion aperture that extends through the bone contacting surface and supporting surface of each respective endplate;
• (iv) an anterior plate extending orthogonally from each bone contacting surface and having at least one bone screw aperture configured to support a bone screw for anchoring into a ventral surface of a corresponding adjacent vertebrae;
• and
• (v) a plurality of anti-rotation slots disposed around each corresponding cage holder and extending through the bone contacting surface and supporting surface of each respective endplate;
• wherein the biocompatible cage comprises a body that extends in a longitudinal direction from a first end to a second end and has a hollow interior,
• wherein the first end of the body is configured to couple to the cage holder of the first endplate and the second end of the body is configured to couple to the cage holder of the second endplate,
• wherein the first end of the body comprises a plurality of protrusions configured to interface with the anti-rotation slots of the first endplate and the second end of the body comprises a plurality of protrusions configured to interface with the anti-rotation slots of the second endplate to thereby suppress radial movement of the biocompatible cage,
• wherein the body comprises a mesh pattern including a plurality of apertures extending through a sidewall of the body that are configured to facilitate bone growth and fusion,
• wherein the plurality of anti-migration features of the first endplate comprise a plurality of serrations that are sequentially spaced, wherein in a top down view, each serration row of the first endplate extends from a first side of the first endplate to a second side of the first endplate along a curved profile and a leading edge of each serration row is oriented at an angle in a direction pointing towards the anterior plate of the first endplate, and
• wherein the plurality of anti-migration features of the second endplate comprise a plurality of serrations that are sequentially spaced, wherein in a top down view, each serration row of the second endplate extends from a first side of the second endplate to a second side of the second endplate along a curved profile and a leading edge of each serration row is oriented at an angle in a direction pointing towards the anterior plate of the second endplate.
