6 Initial Drilling Instruments Used: 1. Trocar Tipped Guidewire (19) 2. 9.5 mm Protection Sleeve (3) 3. 14 mm Protection Sleeve (24) 4. 7 mm Cannulated Drill (28) 5. 9 mm Cannulated Drill (27) 6. Bead Tipped Guidewire (20) With the 9.5 mm Protection Sleeve still in place, insert the 7 mm Cannulated Drill over the guidewire and drill into the medullary canal. The Trocar-Tipped Guidewire will come out when removing the 7 mm Drill. Replace the Trocar-Tipped Guidewire with the Bead-Tipped Guidewire. Reconfirm with fluoroscopy that the Guidewire is seated in the same position prior to proceeding with the 9 mm Drill. Repeat drilling using the 9 mm Cannulated Drill. Remove the 9.5 mm Protection Sleeve. TECH TIPS • It is recommended to drill with the 7 mm Cannulated Drill to just beyond the tibiotalar joint, stopping at the metaphyseal level. Then, drill through the tibial canal using the 9 mm Cannulated Drill. • A 2nd Bead-Tipped Guidewire can be inserted into the back of the drill and pushed against the inserted Bead-Tipped Guidewire ensuring it remains in place while pulling out the drill. • Do NOT forget to replace the Trocar-Tipped Guidewire with the Bead-Tipped prior to reaming. 15
