<p>An intervertebral disc implant for use in the spine includes a superior endplate and an inferior endplate. The superior endplate is configured to articulate about the inferior endplate in an anterior-posterior direction during flexion and extension. The superior endplate is further configured to axially rotate about the inferior endplate during axial rotation, and is further configured to articulate about the inferior endplate along a medial-lateral direction during lateral bending. During axial rotation, the superior endplate is induced to articulate about the inferior endplate along the medial-lateral direction. During lateral bending, the superior endplate is induced to axially rotate about the inferior endplate.</p> |
