A prosthetic device for posterior placement in an intervertebral space defined between an upper vertebrae and a lower vertebrae may include an upper articular portion configured to be at least partially disposed in the intervertebral space and a lower articular portion configured to be at least partially disposed in the intervertebral space below the upper articular portion, the upper and lower articular portions being configured to provide articulating motion to the upper and lower vertebrae. The upper and lower articular portions each may include a posterior section configured to be disposed in a location posterior of the intervertebral space. The posterior section of one of the upper and lower articular portions may include a post, and the posterior section of the other of the upper and lower articular portions may include a receiving portion configured to interact with the post during articulation.
