Set resection Depth
•
Insert tibial cutting block and rotate it into position against
tibia. Attach resection stylus to tibial cutting block.
•
Push release plate of tibial jig up to adjust height of
the tibial cutting block (locking mechanism on cutting
block is in 1 mm increments.) Once tibial cutting block
is at desired position, pin in place with headless pins
provided in instrument tray using distal pin holes.
•
Resect tibia.
•
Press center button when completed.
Finished tibia
•
Use of navigation unit for tibial resection is finished.
TIP:
Press the center button to continue if additional use is
appropriate in this procedure.
Prior to disposal, power off navigation unit by pressing
left and right buttons for 2 seconds.
Prior to resecting tibia, confirm that posterior slope and
varus/valgus angles still match desired values. Use angel
wing stylus to confirm resection level and perform a
visual confirmation of alignment.
TIP:
While setting resection depth, stylus end should not be
pressed into tibial plateau.
TIP:
Resection depth measurement should be set according
to implant manufacturer’s recommendations.
TIP:
If additional support is required, place oblique pin
through tibial cutting block.
TIP:
If additional resection is required, move cutting block
down on pins (2 mm). Tibial jig will need to be removed
to facilitate this.
TIP:
Required saw blade thickness is 1.27 mm (or 0.050 in).
Verify resected tibia with drop rod.
