Trial reduction ( femoral component )
The manipulation femoral component is screwed to the
manipulation femoral adapter (corresponding to the preset
valgus angle) and the trial stem (corresponding to the last
reamer).
Important
There is a danger that the same trial stem will be needed
on the femur and on the tibia. In this case a shorter trial
stem
of the same diameter is mounted on the manipulation
femoral component or a trial stem of the same length
and smaller diameter or no trial stem at all is used.
The manipulation femoral component is inserted with the
hammer.
Important
When using distal and / or posterior tibia blocks,
appropriate manipulation femoral blocks («5 mm», «10 mm»
and «15 mm») are available. They are fixed laterally on the
manipulation femoral component.
The corresponding manipulation tibial insert is positioned.
The implant seat, the kinematics of the joint and the
patella function are checked.
The final decision in favour of a patella replacement is
made at this point (see instructions from page 46).
If the definitive implants are specified, the components are
prepared for assembly (
see instructions from page 48 ).
The manipulation components are removed with the
hammer, starting with the femur.
Important
However, we recommend leaving the manipulation
components with stem and any blocks mounted as a
reference. They are used as a check and as a comparison
to the definitive implant.
