ABSTRACT:
A nerve retractor and guide for laminectomy procedures has a cylindrical body with a single member extending from one end of the wall of the cylindrical body. The single member is formed to enter the intradiscal space to seat upon and maintain spacing of adjacent vertebral bodies during the procedures. The cylindrical body is positioned adjacent to and protects the cauda equina and the nerve roots that extend therefrom. The wall of the cylinder has a portion cut away on the side thereof opposite the extending single member so that the facet, lamina and pedicle bone areas are visibly accessible for removal as required by the procedures.
