Ankle Fix System 4.0 Titanium osteosynthesis system for tibio-talar and tibio-talo-calcaneal fusion Patient Positioning • Place the patient in the supine position with an ipsilateral pelvic sand bag or midlateral position. Surgical Technique Step 1 ————––––––——————————————————————————————————————————— Incision for Ankle Fix Plates (TT Fusion) • Using a lateral approach, make a straight incision to enable the best view of the lateral talar and calcaneal walls. Mobilize the peroneal tendons. Incision for Ankle Fix Plus Plates (TTC Fusion) • Using a lateral approach, make a straight incision longer...

Step 4 ————––––––—————————————————————————————— Temporary Positioning of the Arthrodesis • Temporarily position and fix the ankle alignment with 2 mm K-wires. • Optional: With the fibula removed, there is easy access to the posterolateral aspect of the tibial metaphysis. A K-wire can be placed from the postero-lateral tibia into the neck of the talus over which a cannulated single- and partial threaded screw (with or without a washer) can be applied to provide compression across the arthrodesis. Ensure the screw is of sufficient strength and does not lock the arthrodesis in the direction in which...

Step 8 ————––––––—————————————————————————————— Distal Screw Insertion • Use as many screws as possible to ensure stable fixation. • Attach the screwdriver blade to the handle by pulling back on the coupling, inserting the blade into the shaft, and releasing the coupling. Pull on the blade to ensure that it is locked into the handle. The screwdriver has a ratchet function to simplify screw insertion. Insert the screws bicortically, if possible. The screwdriver can be used to facilitate removal of the screws from the tray by pushing the tip of the blade firmly into the screw head in a vertical...

Step 13 ———––––––—————————————————————————————— Proximal Screw Fixation • Once adequate compression has been achieved, drill, measure, and insert locking screws in the plate in the same manner as with the distal screws for: Ankle Fix – insert screws in the tibial part Ankle Fix Plus – insert screws in the talus and tibial part For tibial screws, use the 3.2 mm instruments (with red markings). Before Compression Device removal • After achieving adequate fixation, remove the fixation pin and the Compression/Distraction Device. Then insert locking screws into the remaining tibial holes. For improved...
