摘要:
A method of preparing a bone to receive a fixation screw through a fixation device includes providing a drill bit sized and configured to pass through a bore in a fixation device positioned in the bone and drilling a passage into the bone and through the bore. At least a distal portion of the drill bit passes through the bore in the drilling step. At least an outer portion of the distal portion of the drill bit has a hardness that is less than a hardness of the fixation nail.
