PHYSICA ZUK SURGICAL TECHNIQUE Step 1 | Proximal Tibial Resection
RESECTION LEVEL The Tibial Resection Stylus should be used to ensure that the selected proximal tibial resection level is achieved. Each tip of the stylus indicates a different depth. The “+2” tip is used to set the resection depth from the most damaged part of the tibial plateau for a minimal cut. In this position, the tibial cutting block removes 2 mm of bone below the tip of the stylus. Alternatively, the “+4” tip is used to set the resection depth from the least damaged part of the tibial plateau. Rest the “+4” tip of the stylus on the cartilage of the least damaged part of the tibial articulation. Insert the Tibial Resection Stylus into the slot of the tibial cutting guide in the desired position. (Fig. 13) PROXIMAL TIBIAL RESECTION When the desired resection level is achieved secure the Tibial Cutting Block with Hexagonal Headless Long Pins using the “0” holes. (Fig. 14) Pay particular attention if the tibial bone is small. If an additional 2 mm tibial cut is required pull out first the central pin and then the Tibial Cutting Block leaving in place the headless pins. Reattach the block ensuring that it passes over the +2 mm holes and secure it with a 35 mm or 50 mm headed screw in the central pin hole. If required the Tibial Cutting Block can be disconnected from the EM Tibial Guide assembly and reinserted after Tibial Cutting block +2 mm repositioning. TECHNIQUE TIP. Alternatively headed screws can be used. In case of a tibial recut replace the headed screws by headless screws so you can move the Tibial Cutting Block to the +2mm holes easily.
