Abstract:

The combination of a driver and fastener that allows a user to insert and remove the fastener by applying larger than normal torque loads to it includes: (a) a fastener with a proximal end handle and a distal end head configured to provide a standard indentation and an additional recess that provides additional surface area that allows larger torque loads to be applied to the fastener, (b) a main driver with a shaft having a central bore, a handle at its proximal end and a head at its distal end configured to allow it to be temporarily inserted into the fastener's head, and (c) an awl driver having an awl shaft with an awl handle affixed to its distal end and its proximal end including a tip configured to allow it to pass through the main driver's bore and be brought into contact with the fastener's head where it is used to cut into the fastener cannula so as to temporarily adhere the awl driver to the fastener.
