An intervertebral implant for separating an upper vertebra and a lower vertebra. The implant includes an upper mount having a first surface sized and shaped for mounting on the upper vertebra and a second surface opposite the first surface. The implant includes a lower mount having a first surface sized and shaped for mounting on the lower vertebra and a second surface opposite the first surface. The implant includes an element positioned between the upper mount and the lower mount spacing the first surface of the upper mount from the first surface of the lower mount by a predetermined distance. The element is configured to permit the upper mount to pivot relative to the lower mount. The element allows the upper vertebra to pivot relative to the lower vertebra while maintaining spacing between the upper vertebra and the lower vertebra.
