Assembling the Implants – Components
The assembling block is essential for safe and gentle assembling of the implants.
Note
When assembling the implant component, always start with the stem first. Then the blocks
can be fixed. Otherwise the block screw may come loose during impacting.
Important
Be aware: if any screw or clamp is missing from the respective component or for any reason
is not sterile, a set of replacement screws and clamps (page 57) is available.
Assembling the tibial component
The tibial component (page 54) is positioned
in the specifi ed position on the assembling
block.
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 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 when using cementless stems that a
pocket is anterior, not a rib.
Fixing the stem (cemented/cementless) to
the tibial component
The prepared automatic hammer with adap-
tor is placed on the stem. The stem is se-
curely attached to the tibial 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 3° posterior slope is
integrated into the tibial component.
