A spring loaded screw and an associated driver for use in orthopedic applications, particularly for temporarily securing cutting guides and the like to the tibia and femur for preparation of the bone surfaces in a total knee replacement. A slidable sleeve on said screw is spring biased away from the driver. As the screw sleeve seats, the sleeve slides upwardly against the compression spring to disengage the driver from the proximal end of the screw. The driver contains a slidably disposed central cylinder which can be axially moved by sliding an externally mounted sleeve. To retract the screw, the driver sleeve is advanced toward the screw to urge the cylinder toward the proximal end of the screw sufficiently far to enable grasping of the proximal end of the screw for retraction thereof. <IMAGE> |
