An instrument useful in performing lumbar arthrodesis with a minimal approach which spares the lumbar muscles from surgical disruption and includes one of two retractor designs having blades angled approximately 90.degree. with respect to each respective retractor handle. One blade is bent at an end portion thereof in a direction away from the handle portion. The other blade has first and second blade faces, with the second face having at least two toothed structures located thereon.
