A system for delivering fluid to a space between two vertebrae is provided. The system includes a tool and an insert configured to be implanted in the space between two vertebrae. The tool includes a proximal end, a distal end and a structure at the distal end configured to be coupled to the insert. The tool further includes a first opening located near the proximal end of the tool, a second opening located near the distal end of the tool, and a passage extending between the first opening and the second opening. The first opening, the passage and the second opening provide a fluid delivery path from the proximal end to the exterior of the tool near the distal end. The second opening is positioned relative to the structure such that fluid is permitted to be delivered from the tool directly into the space between the two vertebrae.
