Abstract
This invention relates to methods and instruments for performing a surgical procedure in a disc space between adjacent vertebrae. A cannula is inserted to create a working channel through the skin and tissue of a patient using a transformational approach to the disc space. A viewing element is used to visualize working end of the cannula and the disc space. A facetectomy is performed through the working channel to access the disc space. The disc space is prepared with various instruments, such as distractors, shims, chisels and distractor-cutters that extend through the working channel. At least implant is inserted into the disc space. The procedure allows bi-lateral support of the adjacent vertebrae with the at least one implant inserted via a unitary, minimally invasive approach to disc space.
