First Claim
1. An artificial vertebral joint for interposition between a superior vertebra and an inferior vertebra, said artificial vertebral joint comprising:
- a pair of bilateral joint subcomponents, each joint subcomponent including,a superior component including a superior vertebra engaging surface;
an inferior component including an inferior vertebra engaging surface; and
a spacer extending between the superior component and the inferior component, the spacer including a first modulus of elasticity and a second modulus of elasticity, the first modulus transitioning to the second modulus with a gradient change.

Abstract
An artificial vertebral joint for interposition between a superior vertebra and an inferior vertebra comprises a pair of bilateral joint subcomponents. Each joint subcomponent includes a superior component including a superior vertebra engaging surface and an inferior component including an inferior vertebra engaging surface. Each joint subcomponent further includes a spacer extending between the superior component and the inferior component. The spacer includes a first modulus of elasticity and a second modulus of elasticity. The first modulus transitions to the second modulus with a gradient change.

20. A method for implanting an artificial vertebral joint between superior and inferior vertebrae, the method comprising:
-
creating an access path to an intervertebral disc space between the superior and inferior vertebrae with a posterior transforaminal approach; inserting a superior component of the artificial vertebral joint into the intervertebral disc space, the superior component including a superior posterior element; inserting an inferior component of the artificial vertebral joint into the intervertebral disc space, the inferior component including an inferior posterior element; inserting a spacer of the artificial vertebral joint into the intervertebral disc space, the spacer comprising an elastomeric material; arranging the superior and inferior posterior elements to extend posteriorly from the intervertebral disc space; and placing the superior posterior element into articulating engagement with the inferior posterior element. - View Dependent Claims (21, 22, 23, 24, 25)
