Dynamic Spacer Device and Method for Spanning a Space Formed upon Removal of an Intervertebral Disc |
摘要 |
A compliant intervertebral spacer according to the present invention replaces a damage intervertebral disc and functions to maintain disc height and prevent subsidence with a large surface area while substantially reducing patient recovery time. The compliant intervertebral spacer for spanning a space formed by upon removal of an intervertebral disc includes two end plates sized and shaped to fit within an intervertebral space and a compliant connector interconnecting the inner surfaces of the two end plates in a manner which limits motion between the plates to less than a total of 5 degrees of motion in any direction. The intervertebral spacer is configured to permanently maintain the disc space between the two adjacent discs without the use of bridging bone.
