Drilling in Two Steps
This is an alternate technique to drilling with the 4.0 mm/4.5 mm
Drill Bit in distal locking procedures. It is used only when there is
insufficient space (less than 47 cm) between the receiver of the image
intensifier and the bone, and a Radiolucent Drive is not available. The
technique entails drilling in two steps: first with the 4.5 mm Drill Bit,
and then with the 3.2 mm Drill Bit.
The following procedure replaces step 5 for the distal locking
technique with the Distal Aiming Device section of this guide which begins here.
