ABSTRACT:
A bone screw screwdriver and method for securely, positively locking a bone screw to the screwdriver. The screwdriver includes an extending handle through which a drive rod is slidingly disposed. A tongue at one end of the drive rod interlocks within a groove in the bone screw. The drive rod selectively locks within the handle to positively interlock the bone screw with the screwdriver. A tab on the screwdriver engages a corresponding recess on the bone screw to prevent rotation and removal of the bone screw from the screwdriver.
