4-in-1 Femoral Cuts
Choose the Vanguard XP Femoral 4-in-1 Block that
matches the selected size (Figure 17).
Place the block into the 1/8 inch distal femur holes.
Note:
A 1.37 mm feeler blade can be used to
determine the amount of anterior bone resection.
Ensure the block is sitting flush against the distal
femur.
If additional stability is required, 1/8 inch quick release
drill pins or the threaded headed pins can be placed in
the angled side holes provided on the femoral 4-in-1
block (Figure 17A).
Once the block position is satisfactory, resect the
anterior and posterior bone and the anterior and
posterior chamfers with a 1.37 mm thick saw blade in
a standard configuration (Figure 17).
After making the anterior resection, assess the anterior
resection relative to the anterior cortex.
If downsizing is possible, the initial block can be
removed and the smaller sized block applied. The
anterior and posterior femur and chamfers then can
be resected.
Note:
Take care not to stretch the soft tissues by
over-retracting the ligaments.
