Guidewire Insertion
Instruments Used:
1. Trocar Tipped Guidewire (19)
2. 3.3 mm Protection Sleeve (4)
3. 9.5 mm Protection Sleeve (3)
4. 14 mm Protection Sleeve (24)
Assemble the 3.3 mm, 9.5 mm, and 14 mm Protection Sleeves as shown in Inset A. Place the Protection Sleeve
Assembly against the plantar surface of the calcaneus. Insert the Trocar Tipped Guidewire (B) into the 3.3 mm
Protection Sleeve, taking care that the guidewire tip is contacting the inferior aspect of the calcaneus. Drill the
guidewire through the calcaneus and talus into the tibial medullary canal. With the Protection Sleeve abutted
against the bone, confirm proper depth has been reached by reading the lasermarks off the back of the Protection
Sleeve (C). When satisfied with the guidewire placement, remove the 3.3 mm Protection Sleeve leaving the Trocar
Tipped Guidewire in place.
TECH TIP
• Fluoroscopy should be utilized throughout the entire insertion process to ensure centered guidewire placement
in the tibial medullary canal on both the anterior and lateral views.
