S U R GI C A L T ECHNI Q U E EXaMPLE OF application: SUBTALAR FUSION (Example of subtalar fusion surgical technique with ø6.0 mm screws and associated instruments.) Screw the guide for the Ø1.6 mm pin (ANC429) into the soft tissue protection sleeve (ANC441). Insert the pin (33.0216.180) through the assembly and remove the latter. Screw the reamer tip (ANC418) in the extension stem (ANC412). Read the length of the screw on the measuring gauge of the extension stem (ANC412) at the rear of the pin. NB: Screw length can be read on both sides of the extension stem: Use the graduated side corresponding to the chosen screw diameter. - 1 side is graduated for ø4.0 mm screws - 1 side is graduated for ø6.0 and 8.0 mm screws Remark: In case of dense cortical bone, it is recommended to drill before the screw insertion. The cannulated drill bit (ANC415) is inserted over the pin and through the soft tissue protection sleeve (ANC441). Read the screw length on the drill bit, at the rear of the protection sleeve.

Prepare the first cortical using the reamer tip + extension stem assembly (ANC418+ANC412) so that the screw head can be safely inserted. To make the next steps easier, make a note of the number indicating the upper level of the skin. Screw the screwdriver tip (ANC421) into the 2nd extension stem (ANC412). Insert the screw over the pin using the screwdriver. The number read on the gauge during the reaming phase (step 4) can be used as an indicator of the insertion depth: insertion is completed when the number is reached. Remove the pin and check if the implant is on the same level or lower than...
