PHYSICA ZUK SURGICAL TECHNIQUE Step 6 | Sizing and Finishing the Tibia
Ensure the Tibial Trial plate is properly seated according to the cuts and the anatomy of the tibia and flush against the bone. (Fig. 50) When the Tibial Trial Plate is positioned you can secure the Tibial Trial Plate with one Tibial Headed pin or with a 20mm screw. (Figs. 51a and 51b) The 20mm Tibial Headed Pin can be inserted and removed with the Tibial Pin Inserter. The 20mm Tibial Headed Screw can be inserted and removed with the Pin Driver.

TECHNIQUE TIP. To facilitate insertion of the Tibial Trial Plate, externally rotate the tibia while the knee is flexed.
TIBIAL PEG PREPARATION Use the Tibial Drill to drill the two tibial peg holes. (Fig. 52) Note that these holes are angled 20° posteriorly. It is recommended to start with the anterior peg hole. The drill is automatically guided to ensure that the holes are at the correct inclination. (Fig. 52 inset) Although the pegs on the implant are at 90°, the drill is designed so that the pegs will fit into these angled holes. Leave the Tibial Trial Plate in place on the bone.
