Abstract
Official abstract text for this publication.
A four-component artificial intervertebral disc may provide six degrees of movement: flexion, extension, lateral bending, axial rotation, axial deflection, and anterior/posterior translation. The disc may include a superior endplate, a superior core, an inferior core, and an inferior endplate. The superior endplate may include a concave mating surface, and the inferior endplate may include a spherical mating surface. The superior endplate may roll across the superior core to provide flexion, extension, and lateral bending. The superior endplate may twist or rotate atop the superior core to provide axial rotation, and the superior endplate may slide over the superior core to provide anterior/posterior translation. The superior core may be connected to the inferior core, and the inferior core may be connected to the inferior endplate. The inferior core may be made from a flexible material that may enable the artificial disc to expand or compress vertically.
First claim
Opening claim text (preview).
What is claimed is: 1. An artificial disc comprising: a superior endplate comprising a bi-convex superior surface and a concave inferior surface; a superior core comprising a convex superior surface configured to contact the concave inferior surface of the superior endplate; a flexible inferior core having an upper wall and a lower wall, the flexible inferior core configured to connect to the superior core, the upper wall and the lower wall divided by a mating groove, wherei…
