The preferred embodiment of the present invention is generally described as a lordotic pre-sacral rod implant, or implant construct, for use in association with spinal fusion procedures. In an embodiment, the lordotic pre-sacral rod implant incorporates a washer configured to press against the endplate of the L5 vertebral body and thereby force the vertebral bodies of the lumbosacral junction into a lordotic orientation.

Certain embodiments of the invention relate to a surgical procedure resulting in the fusion of transverse processes. The disclosure herein presents novel approaches for accessing transverse processes of the spine, novel methods for the delivery of fusion material for the fusion of said transverse processes, and novel tools to facilitate the procedure. Certain embodiments of the invention include a graft delivery assembly, which has a delivery shaft, delivery sheath, and at least one curved rod. Bony material is position with a graft delivery assembly, in which retraction of the delivery shaft or sheath places the bone fusion material to the fusion site. The graft delivery assembly further includes features to decorticate and prepare the bone surface for fusion.
