Abstract
An orthopedic fixation screw for anchoring a bone graft in a bore formed in a bone mass. An elongate cylindrical nose portion has a substantially smooth outer surface for being received without interference into the space between the graft and a wall of the bore. A threaded portion interferingly engages the graft and a wall of the bore as said threaded portion is rotated when the nose portion is so received. An hexagonal socket in the rear of the screw receives either a driver having tapered hexagonal walls for tightly receiving the screw on the driver during installation or a conventional hex driver for removing an installed screw in the event the tapered driver is unavailable when the screw is to be removed.
