Remark
When putting the augmentations into place, care
must be taken to ensure that the lettering is legible. If
it is not, this means that the augmentation has been
positioned with the wrong side facing out.
The balanSys REV system comprises straight stems
and stems with a 4 mm offset.
To prepare the cutting block of the 3in1 system, first
tighten the anterior screw and then loosen it again
by one quarter of a turn, to secure the femur offset
guide in place. It must be possible to turn the femur
offset guide.
Slide the assembled combination (cutting block of the
3in1 system plus the offset sleeve insert and the offset
guide) onto the shaft of the reamer. Then push the
rotation guide (71.34.0665) along the shaft and fit it
into the holes provided on the cutting block.
Once the assembled combination is correctly posi-
tioned, it is possible to make several different settings
at the same time:
• Determine the AP and ML position of the femoral
implant, using the offset guide
• Check the flexion gap, with the help of the trial
inlay for the spacer as defined in the extended
position (79.02.0730 to 79.02.736) and the size
12 femoral spacer block (79.02.0652)
• Make the final setting of the femur rotation
