Alignable Tools for Preparing an Intervertebral Site for Implanting a Prosthetic Intervertebral Disc and a Method for Using Those Tools

摘要

We describe various alignable tools, in particular, trials and chisels, that may be used in preparing an intervertebral site in a spine, the site being suitable for placement of a prosthetic intervertebral disc as a replacement for a natural disc in that spine. We also describe methods of using those tools.
