Abstract
Some embodiments of the invention disclose an apparatus for achieving rapid mechanical fusion between two adjacent vertebral bodies by positioning a fusion member with one or more channels between the two vertebral bodies. Once the fusion member properly positioned, one or more needles are passed through the fusion member's channels and advanced into the marrow space of the adjacent vertebral bodies. Each needle has a lumen for receiving adhesive material and supplying said material to the marrow space of the adjacent vertebral bodies. The adhesive material is for adhesively bonding the needle to the adjacent vertebral bodies. In some embodiments, a needle also has various surface contours along its shaft, including angled teeth and backfacing ridges.
