Abstract
Intervertebral fusion implant cages and related methods are described herein. The cages may be used to assist with fusing together adjacent vertebrae when a displaced or damaged spinal disc is surgically removed. The cages include windows that allow the bone graft to grow from one vertebra through the cage and into the adjacent vertebra (e.g., cervical vertebrae). The cages include a number of features which enhance its performance during use.

- a curved superior surface shaped to match anatomical curvatures of an adjacent vertebra;
- a curved inferior surface shaped to match anatomical curvatures of an adjacent vertebra;
- an anterior wall;
- a posterior wall;
- a first sidewall connecting the anterior wall to the posterior wall;
- a second sidewall connecting the anterior wall to the posterior wall at a side opposite the first sidewall;
- an inner wall extending from the anterior wall to the posterior wall;
- a first window extending from the superior surface to the inferior surface and defined between the inner wall, the first and second sidewalls, the anterior wall and the posterior wall;
- and
- a second window extending from the superior surface to the inferior surface and defined between the inner wall, the first and second sidewalls, the anterior wall and the posterior wall.
