A screw for use with vertebral members having one or more slots that extend along at least a section of the length. The slots are sized to contain bone growth material. A portion of the screw length may also include threads to assist in inserting and anchoring the screw into a vertebral member. In use, the bone growth material is loaded into one or more of the slots. Once loaded, the screw may be inserted into the vertebral member to a predetermined depth. At this depth, the slots deliver the bone growth material to a position to allow for bone growth to occur.
