Mount aiming arm and insert trocar assembly
Attach the Aiming Arm for Standard Locking (357.115) to the
insertion handle. Insert the turquoise triple trocar assembly
(Protection Sleeve 11.0/8.0 (357.118), Drill Sleeve 8.0/4.9
(357.097) and Trocar
4.9 mm (357.098)) through the
cranial hole of the aiming arm and, after a stab incision, to
the bone. Remove the trocar.

Drill and measure length for locking screw
Drill through both cortices using the calibrated Drill Bit
4.9 mm (357.099) stopping just after penetrating the far
cortex. Confirm the drill bit position radiographically. Make
sure the drill sleeve is in contact with the bone and read the
length for the locking screw from the ringmarks on the drill
bit. The locking screw should not surpass the medial cortex
by more than 2 mm.
Alternative
The Depth Gauge for Locking Bolts (357.791) may be used to
determine the length of the locking screw. Remove the Drill
Sleeve 8.0/4.9 and insert the measuring hook through the
Protection Sleeve 11.0/8.0. Determine the length of the
locking screw by adding 2 mm to the reading on the depth
gauge.
