Minimally invasive facet release is performed during spine surgery. The minimally invasive facet release may be performed at a single level or over multiple levels. The minimally invasive facet release may be performed through a working corridor instrument which may be a tissue retractor or an access tube. When coupled with a minimally invasive pedicle screw fixation system, the facet release methods described enable a surgeon to correct a wide array of spinal deformities in a purely minimally invasive fashion.
