Abstract
A surgical tool in the form of a three piece bone graft inserter includes a pair of concentric cylinders having elongated apertures formed in the side walls of the cylinders to allow the interior of one of the cylinders to be loaded with the bone graft material, and a plunger that extends through both cylinders. Rotating one of the cylinders thereby “closes” “the apertures creating a closed cylinder filled with the graft material. The ends of the cylinders are inserted into the bone void and the plunger is advanced forward to move the graft material into the bone cavity.
