An insertable and removable disc space spreader is provided for maintaining proper space between adjacent vertebral bodies during laminectomy procedures. In general, the disc space spreader of this invention provides a more gradual and therefore gentler entry into the intradiscal space and subsequently fewer traumas to bone and tissue contained therein than previously known spreaders. The spreader, in one embodiment, is able to form grooves in the vertebral bodies to subsequently facilitate insertion of a tang retractor used in these procedures.
