Position the image intensifier 1.   Position the image intensifier so that both transverse distal holes appear on the monitor, and the X-ray beam is aligned with the axis of the most proximal of the distal locking holes (unless this hole is too near the fracture).

The locking hole will appear completely round on the screen. To facilitate viewing of the Distal Aiming Device, the image should appear in the lower middle half of the screen.

Lock the image intensifier in this position until drilling is complete. Cover the leg with the Radiation Shield. To prevent the beam intensity from being automatically raised, do not allow the shield to extend into the radiation field.

Using image intensification to verify the location of the incision, make a stab incision over the hole, down to the bone.
