Abstract
A method for accessing the spine includes making an incision in the skin of a patient. The skin and tissue can be dilated, and a cannula inserted through the dilated skin and tissue. The cannula includes a distal end positioned adjacent a first working space that includes paraspinous tissue. The cannula can be repositioned through the incision to a second working space adjacent the distal end of the cannula.
