Patent ID: 8920505

Claim:
An intervertebral fixation device, the device comprising: a weight-bearing shell including a first and second opposing sidewalls, a keyway that extends from and through a first opposing sidewall to and through a second opposing sidewall of the first and second opposing sidewalls, and a first axis of rotation and a different second axis of rotation that are outside the keyway and extend from the first opposing sidewall to the second opposing sidewall of the first and second opposing sidewalls; a first anchor rotatably coupled to the weight-bearing shell about the first axis of rotation and disposed in a first orientation in relation to the weight-bearing shell; a second anchor rotatably coupled to the weight-bearing shell about the second axis of rotation and disposed in a second orientation in relation to the weight-bearing shell, the second orientation divergent from the first orientation; and a key configured to be locked in the keyway supporting the first anchor in a third orientation in relation to the weight-bearing shell and the second anchor in a fourth orientation in relation to the weight-bearing shell, the third orientation divergent from the fourth orientation.
