Preparation
(cont.)
Silver/Gold Broach Preparation
Attach the smallest sized broach that best fits the size
of the tibial defect to the DR handle by pulling back the
lever and locking into place (Figure 6).
Note:
The 0, +5 and +10 marks on the DR handle are
for femoral use only.
Slide the broach over the extension post and align
anteriorly to the tibia. Fully seat the broach. Sequentially
broach until the desired fit or stability is achieved
(Figures 7 and 8). To remove the DR handle/broach,
rotate the lever to the unlocked position and use the
slap hammer to remove the broach from the tibia
(Figure 9).
Ensure the broach sits at or below the proximal surface
of the tibia. Check for rotational stability of the broach.
If the broach is unstable or the defect is unfilled, repeat
with sequentially larger broaches until the desired fit is
achieved.
Note:
If the broach was not prepared at or distal
to the proximal surface of the tibia, it will cause the
tibial baseplate to sit proud.
Note: The silver broaches are designed to be
broached up to 20 mm below the proximal surface
of the tibia.
Gold Broaches
The gold cone broach is a coupled device. Broaching
deeper in the proximal tibia will drive the provisional
stem deeper into the tibial canal.
If the gold broach needs to sit more distal, remove the
stem extension post/stem provisional construct and
proceed with freehand broaching using the DR handle
and the gold cone broaches. The stem extension
post/stem provisional construct must be removed.
Broaching will drive the provisional stem deeper into
the tibial canal which could potentially cause the tibia
to fracture.
Note:
If a cut was made for a tibial augment, the
cone broach must be impacted until the top of the
broach is level with or slightly below the augment
cut.
Remove all instruments from the tibia.
