PHYSICA ZUK SURGICAL TECHNIQUE Step 1 | Proximal Tibial Resection
Insert the EM Tibial Guide Cutting Block Connection into the Tibial EM Guide Height Adjuster by pressing the red button. (Fig. 8) . Place the knee in 90° of flexion with the tibia translated anteriorly and the whole leg held firmly in place on the surgical table.
Position the EM Tibial Guide assembly around the ankle and place the cutting block against the proximal tibia.
Position the EM Tibial Guide assembly following the bony landmarks:
• • • •
Medial / Lateral malleoli;
Tibial Crest;
Tibial tubercle (2/3 - 1/3);
Second Metatarsal.
The red button at the proximal end of the Tibial EM Guide Height Adjuster is used for macro-adjustment of the height of the proximal tibial cutting block.
Adjust the EM Tibial Guide assembly approximately along the length of the tibia.
Figure 8
The red dial on the EM Tibial Guide Height Adjuster is used for micro-adjustment of the height of the tibial cutting block. (Fig. 8 inset) Fine-tune the proximal tibial cut height exactly to achieve the need of the patient’s knee by using the Tibial Resection Stylus, feeler blade or by checking the X-Rays. When the approximate M/L position is achieved place a 35 or 50 mm headed screw into the proximal tibial cutting block central hole by using the pin driver to fix the position of the EM Tibial Guide. This still allows some degree of fine tuning in height, slope and varus/valgus. (Figs. 9 and 9 inset)
