1. A dynamic intervertebral spacer comprising:
a monolithic spacer having an anterior portion, a posterior portion, a superior surface, an inferior surface, and an open center portion, wherein said monolithic spacer is configured to be implanted in a space between adjacent vertebral bodies with the superior surface engaging a superior vertebral body and the inferior surface engaging an inferior vertebral body;
wherein the spacer is split to provide motion in the anterior/posterior direction between a bone attachment portion of the superior surface and a bone attachment surface of the inferior surface of between 1 and 5 degrees;
wherein a portion of the spacer is configured to act as a torsion spring to allow the anterior/posterior motion;
wherein the open center portion is configured to receive bone graft; and
wherein inferior and superior surfaces are angled with respect to one another in order to restore lordosis.
