Securing the stem
With the stem screw the stem is additionally
secured. The screw has to be tightened with
the provided screwdriver.
Note
The stem screwdriver is intentionally slim
designed and must be used carefully.
Assembling the tibial blocks
There are blocks with a thickness of 5 mm,
10 mm and 15 mm available for the tibial com-
ponent (page 57).
To enable tibial block assembly, the required
PE pegs must fi rst be removed.
Note
When using blocks, care must be taken to
ensure that the femoral implants are dry and
clean. Observe the appropriate size combi-
nations.
The tibial blocks are also fi xed mechanically
with the preassembled screws with the
screwdriver with torque. The required torque
is reached when the line reaches the "Stem/
Block" position (4.5 Nm).
Notes
The tibial blocks can be inserted either medi-
ally or laterally (except tibial blocks size
15 mm). The 15 mm tibial blocks are anatomi-
cally conical tapered and therefore differently
used (R-Lat/L-Med, respectively; L-Lat/R-Med).
The screws are screwed into the block through
the tibial component and must always be
countersunk.
