2. 4 mm Free-Hand Drill
3. 8 mm Guide Sleeve (9)
4. Free-Hand Screw Depth Gauge
5. 3.5 mm Hex Driver Shaft (26)

For 260 mm and 300 mm length Implants, a screw may also be free-handed into the most proximal tibial screw
hole. This screw can also be a substitute for the tibial screw described in Step 15. Drill using the 4 mm Freehand
Drill in the most proximal tibial screw hole using perfect circles technique under fluoroscopy. Determine the
appropriate screw length by inserting the Free-Hand Screw Depth Gauge. Insert the Cortical Screw as described
in Step 12. Use fluoroscopy to determine when desired depth is reached and the screw is fully seated.
