An instrument for selectively decorticating a bony surface is described. The instrument may have a decorticating implement having a truncated scoop on its medial face and an inclined blade disposed on its opposing lateral face. The blade edge may be coincident with the linear distal edge of the truncated scoop. Also described is a method for using such an instrument to selectively decorticate a bony surface in order to prepare it for service as a bone graft bed.
