1.
Select the appropriate size A/P resection block and
place over the pins through the appropriate anterior
or posterior referencing holes. Ensure that the cutting
block is flush with the resected distal femur (Figure 17).
2.
Prior to bone resection, insert the resection check
(angel wing) into the anterior blade slot of the A/P
resection block to check the plane of the resection and
to avoid any chance for notching (Figure 17a).
Note: Component size can also be estimated by the
M-L dimension of the cutting block at the condylar
and junctional region. The cutting block M-L width
corresponds to the standard size (not Narrow)
ANTHEM™ femoral component.
AP translations
Should any fine adjustment be required at this stage,
then an option is to use the anterior OR posterior
referencing translation blocks. These are designed
to allow fine adjustment of the A/P position of the
femoral cutting block.
To use the translation block remove the trochar pins,
placing the spikes on the back of the block into the
same location holes used for the A/P cutting block,
and then re-drill pins in the new position. It is useful
to mark the original pin track holes with a marking
pen in order to properly identify the new holes.
Care must be taken when using these translation
blocks as any translation of the cutting block may
affect both the posterior flexion space and patello-
femoral joint space.
3.
In order to secure the block there are additional
fixation holes medially and laterally as well as a
central pin hole. Once secure remove the anterior or
posterior referencing pins from the block..
