Assembling the femoral component
The femoral component (page 54) is posi-
tioned in the specifi ed position on the
assembling block.
Fixing the stem (cementless) to the femo-
ral component
The stem (page 58) is inserted into the taper.
It is recommended to turn the stem so that
the security screw is positioned medially
(lower stress in this zone, and in addition will
facilitate the screwing later on), and that no
fi n but a groove is anteriorly positioned
(thereby a larger surface is in contact with
the internal cortical bone).
Important
Pay attention that the tapered connection is
undamaged, clean and dry before mounting
and by using cementless stems that a pocket
is anterior, not a rib.
The prepared automatic hammer with adap-
tor is placed on the stem. The stem is se-
curely attached to the femoral component by
impacting the stem three times.
Notes
When using 200 mm stems, place the cross-
shaped stem protector into the adaptor for
automatic hammer.
A stem connection with 6° valgus angle is
integrated into the femoral component.
