The Ø 8 mm IM rod is carefully inserted using
the modular handle to approximately the
isthmus of the femoral IM canal and removed
again. It is important to work carefully to pre-
vent excess pressure in the IM canal.
The femoral IM canal is opened further with
the Ø 8/14 mm stepped drill. Note that the
drill is positioned at the entry point of the
femoral IM canal, previously determinated by
the IM drill. The drill direction is along the
femoral axis. Drill as far as the stop.
Note
The femoral IM canal, which determines the
implants stem position, must be opened
carefully (reference for the femoral position)
to prevent the development of a relative ex-
tension position (risk of notching) or flexion
position (projecting patella).
Preparing the femoral anchorage
Reamers are used carefully and in progres-
sive stages (starting with Ø 10) to ream to the
required stem diameter and depth.
Notes
Reamers are available in diameter Ø 10,
Ø 12, Ø 14, Ø 16, Ø 18 and Ø 20. The depth
indicator is on the reamer: observe the laser
markings (95, 120, 160 and 200).
When using cemented stems, the Ø 12 mm
reamer is used to drill to the desired depth
and the corresponding cementless trial stem
is used. The optional cemented trial stems
are only used with the trial components (not
with the instruments)!
The 200 mm length is only available in the
cementless version.
