Abstract

A spinal implant insertion guide is disclosed. The insertion guide includes at least one channel suitable for receiving and facilitating movement of a spinal implant into an intervertebral space between two vertebrae and a portion suitable for insertion into the intervertebral space. In embodiments for use with spinal implant having multiple pieces, the pieces of the spinal implant remain in cooperation throughout movement. The guide may further include a plunger for facilitating the movement of the spinal implant.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] his application claims the benefit of the filing date of U.S. Provisional Patent Application No. 60 / 601,461 filed Aug. 13, 2004, the disclosure of which is hereby incorporated herein by referenceBACKGROUND OF THE INVENTION [0002] The present invention relates generally to apparatus and methods for use in spinal disc arthroplasty, and more particularly, to apparatus and methods for use in the insertion of disc replacement implants into the intervertebral space between two adjacent vertebrae. [0003] Whether due to injury, wear, or genetic defect, intervertebral disc degeneration is a problem suffered by many people. Typically, this spinal problem has been addressed by removing the disc material and replacing it with a spinal implant which fuses two adjacent vertebrae. Recently, however, there has been a significant amount of activity directed toward filling the intervertebral space with spinal implants that permit relatively natural movem...
