A surgical screw system comprising a cannulated screw, a guide wire and a driver. The screw has a head, a tubular body with a bore, and a tip opposite the head. The guide wire, shorter than the screw, is slidably disposed within the bore of the screw. The guide wire has a working end deployable beyond the tip of the screw, and the working end is sharpened to penetrate the bone and produce a pilot hole when an axial force is applied. The guide wire extends to deploy the working end beyond the tip to create the pilot hole, and fully retracts into the screw upon installation of the screw. The driver passes through the head of the screw into the bore, and applies the axial force to the guide wire. The driver may be used to drive the screw into the bone, and is removable from the screw.
