Precaution:
Ensure all locking caps are fully re-
duced and provisionally tightened (see “Insert
1-step locking cap”). Failure to do so could poten-
tially lead to a misalignment.
Finally tighten one locking cap completely to create a
fixed point for distraction (see “Perform final tighten
-
ing”). Reverse the locking cap of the screw to be relo-
cated a quarter of a turn.
Use the compression forceps to compress the construct.
Once in the desired position, tighten the locking caps
with the screwdriver.
The rod holding forceps can be used as a temporary
point of compression when adjacent pedicle screws are
too distant.
Note:
Always fully seat the counter torque on the
rod. The instrument must be perpendicular to the
rod during tightening.
