Slide the femoral stylus backward or forward so that
the size indicated on the femoral stylus matches the
femoral size indicated on the femoral sizer guide.
The point at which the femoral stylus contacts the
bone marks the peak of the femoral anterior flange
(Figure 16d).
7.
If between sizes, it is recommended to use the
following protocol depending on preferred referencing
technique.
Posterior referencing
Choose the next larger size (ie, upsize) to reduce the
risk of anterior notching
Anterior referencing
Choose the next smaller size (ie, downsize) to avoid
overstuffing the flexion space
Note: The average difference between sizes of the
ANTHEM™ femoral implant sizes is 3mm.
8.
Once implant size and external rotation are determined
place two pins in the appropriate anterior OR posterior
referencing pin holes (not both). Remove the Femoral
sizing guide by sliding it off the secured trocar pins,
leaving the pins in situ (Figure 16e and 16f).
