An intervertebral fixation device and system are disclosed, including a weight-bearing shell, first anchor, second anchor, and key. The shell includes a first and second opposing sidewalls, a keyway that extends between and through the first and second sidewalls, and a first axis of rotation and a second axis of rotation that extend between the first and second sidewalls. The first anchor is rotatably coupled to the shell about a first axis of rotation and is disposed in a first orientation. The second anchor is rotatably coupled to the shell about a second axis of rotation and is disposed in a second orientation. The second orientation is divergent from the first orientation. The key is configured to be disposed in the keyway to support the first anchor in a third orientation and the second anchor in a fourth orientation. The third orientation is divergent from the fourth orientation. |
