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 transforaminal 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.
