Optional Technique

If desired, the cemented tibial drill stop collar, may be
used to aid in drilling to the correct depth. Depress
the button on the cemented tibial drill stop collar and
slide the cemented tibial drill stop collar to the desired
size-specific position on the cemented tibial drill
(Figure 52).

Confirm that the correct size is displayed in the
cemented tibial drill stop collar window (Figure 53)
and that the cemented tibial drill stop collar is locked
on the cemented tibial drill.

Technique Tip:

Verify that the cemented tibial drill

stop collar is locked on the cemented tibial drill by
attempting to slide the cemented tibial drill stop
collar on the cemented tibial drill by hand. The
cemented tibial drill stop collar will make an audible
click when it locks on the cemented tibial drill.

Technique Tip:

Insert cemented tibial drill into

cemented tibial drill guide prior to drilling.

After positioning the cemented tibial drill stop collar in
the proper position, drill through the cemented tibial
drill guide until the cemented tibial drill stop collar
contacts the cemented tibial drill guide (Figure 54).
After drilling is complete, remove the cemented tibial
drill and cemented tibial drill guide from the cemented
tibial sizing plate.
