8 21 Tibial Cutting Jig 9403-2120-RE 9403-2220-RE 19 Tibial IM Alignment Guide 9403-2103-RA 20 Tibial Stylus 9403-7101-RA Position the Tibial Cutting Jig 21 onto the Tibial IM Alignment Guide 19 . With the thumb screw held loosely, the Tibial Stylus 20 may be used to establish the appropriate height position of the Tibial Cutting Jig 21 . NOTE : The Tibial Stylus 20 allows two options to position the Cutting Guide: 2 mm or 9 mm cutting levels. When the Tibial Stylus 20 tip marked 2 mm is positioned on the low point of the tibial plateau, the bone resection will be 2 mm below the contact point of the stylus tip. If the 9 mm stylus tip is positioned on the high point of the tibial plateau, it will position the Tibial Cutting Jig 21 9 mm below the contact point of the stylus tip. With the Tibial Cutting Jig 21 properly positioned, two 3.2 mm Twist Drills 11 are placed into the “0” hole locations. Additional Drills 11 may be used in the peripheral holes provided. With the Tibial Cutting Jig 21 secured, the T-Handle 5 is re-assembled onto the Tibial IM Rod 18 for the removal of the Tibial IM Rod 18 and Tibial IM Alignment Guide 19 . The Tibial Cutting Jig 21 will stay in the position. Now the proximal tibial resection may be performed utilizing a 1.27 mm saw blade. Once the resection is completed, the Cutting Guide and Pins may be removed for subsequent trial reduction. NOTE : Prior to resection, if the surgeon wishes to increase or decrease the tibial resection thickness, the “+2” or “-2” hole locations may be utilized to re-position the Tibial Cutting Jig 21 . B.
