Locking Distally

Distal locking is performed using the 6.0 mm Titanium Locking Screws [450.861-450.872].

Attach the Aiming Arm for 6.0 mm Titanium Locking Screws [357.096] to the Insertion Handle. Insert the triple trocar assembly* into the Aiming Arm and through a stab incision to the bone. Remove the trocar.

Drill through both cortices using the 5.0 mm Calibrated Drill Bit [357.099], stopping the drill immediately after penetrating the far cortex. Confirm drill bit position radiographically. Ensure the drill sleeve is pressed firmly to the cortex and read locking screw length directly from the calibrated drill bit at the back of the drill sleeve. The calibrated drill bit provides a direct measurement.

Note:
Since drill bit position directly represents locking screw position in bone, the locking screw will be too long if the drill bit is over- inserted, or if the drill sleeve is not pressed down to the cortex.
