An intervertebral prosthetic disc is disclosed and can be installed within an intervertebral space between an inferior vertebra and a superior vertebra. The intervertebral prosthetic disc includes a superior component that can be configured to engage the superior vertebra and an inferior component that can be configured to engage the inferior vertebra. A nucleus can be disposed between the superior component and the inferior component. The nucleus can be configured to allow relative motion between the superior component and the inferior component. Further, the intervertebral prosthetic disc can include at least one nucleus containment feature that can be configured to prevent the nucleus from migrating with respect to the superior component and the inferior component without interfering with the relative motion between the superior component and the inferior component in any direction.
