Optional Technique
Screw Insertion with Retaining Sleeve, Locking
When using a ratchet handle, make sure to set it to neu-
tral setting.
Rotate the grey knob of the retaining sleeve clockwise.
Firmly tighten to secure the implant, using the handle as
countertorque (6).
Push the green locking ring toward the grey knob (7). If
required, set the ratchet handle to the forward setting to
insert the screw.
To release the screw from the retaining sleeve, retract
the grey locking ring towards the handle, rotate the
silver knob counterclockwise and remove the screw-
driver (8).
Notes:
•
Polyaxial screwheads need to remain free and mo-
bile after insertion to allow accurate alignment to
the rod during locking cap insertion and final
tightening.
•
The mobility of the screwhead cannot be assessed
while the holding sleeve is attached.
