Summary:A surgical bone screw (1) and driver (31), and a method for using them for repairing an osteotomy or fracture. The screw has a shaft having a head (5) at its proximal end, screw threads (3) at its distal end and a compression member (7) between the head and the screw threads. In an embodiment, the threads are self-tapping and self-drilling, the head is polygonal, and the sides of the polygon are convex. The driver turns the screw until the threads cross a fracture site and the compression member contacts the proximal bone fragment. The threads and compression member draw the fragments together and leaves the head entirely clear of the bone surface. The screw is removed through a small incision. Tilting the driver to allow the socket to engage an inwardly extending lower portion of the head permits the driver to lift the screw out of the bone.
