             11   Pre-Drilling For The gUiDe Wire


                  Drill through the cortical bone with the yellow 3.2 mm

                  spiral drill (33).


              !   The threaded Kirschner wire may damage or bend by
                  the cortical bone, therefore is important to rough-drill it
                  by the tempered spiral drill.







             12   INSERTION OF ThE GUIDE WIRE



                  Insert the 3×400 mm threaded Kirschner guide wire (30)
                  into the femoral head to a level approximately 5 mm
                  below the subchon dral bone.


                  Confirm the position of the guide wire within the head
                  with ap and lateral views.







             13   LENGTh MEASUREMENT


                  Measure the length of the dynamic screw on the guide
                  wire with the gauge (19).


              !   Verify that drill sleeves are against bone.
                  After the determination of the length of screw - while

                  keeping the wire remove the drill sleeve (25).






             14   DRILLING FOR ThE DYNAMIc ScREW


                  Align the length`s buffer to the right position, which is
                  placed on the drill for the dynamic screw (33).


                  Drill through the soft tissue protector till buffer (24).
