Controlling the stem position
An extramedullary reamer alignment guide, which is
attached to the reamer, can be used to check the
position of the stem in axial alignment and depth (the
end of the reamer alignment guide
corresponds to the
tip of the reamer).
Preparing the femoral stem connection
I
M positioning and control with trial stems
The stem connection recess is drilled with the Ø 10/20 mm
stepped drill until the engraved marking «Femur»
respectively «Femur PS» (corresponding to the joint line).
The chosen trial stem is attached to the extension for trial
stem (Ø 8 mm) and with the modular handle carefully
inserted into the femoral IM canal so the line marked with
«MIN.» is approximately level to the distal bone resection.
The modular handle is now removed. It is important to
avoid putting excessive pressure in the femoral IM canal.
Important
With too short IM guidance, the alignment may be incorrect
(varus / valgus, extension / flexion). Therefore the 40 mm
trial stems can’t be used for the IM application!
