For implanting the S Spinal System implant, the following steps need to be
carried out:
4
Select the appropriate S Spinal System variant and anchoring implants
according to indication, preoperative planning and bone situation found
intraoperatively.
4
When choosing the S Spinal System screw types, make certain to select
the correct diameter, length and canal orientation.
Trauma to the spinal column and nerve roots due
to incorrect application!
Position instruments and insert pedicle and
polyaxial screw only with the aid of a radio-
graphic visualization or navigation system.
WARNING
To avoid internal stress on, and weakening of the implant: avoid scoring
or scratching of the implant components.
Do not change the shape of any metal implants except for the rods and
4
transverse connectors of the Aesculap S Spinal System.
Do not bend back, or bend excessively, the rods and transverse connec-
tors.
4
Always use bending instruments of the S
for bending the rods and transverse connectors.
For positioning the clamping screw, always use the clamping screw
insertion instrument intended for this purpose.
For tightening and loosening the clamping screw, always use the screw-
driver and countering instrument intended for this purpose.
Always tighten the clamping screws with the torque wrench intended
for this purpose.
Risk of injury due to improper mounting of the
clamping screw!
Set the clamping screw in place correctly.
Make certain that rods are correctly posi-
tioned on the floor of the groove.
WARNING
Fully tighten the clamping screw, using the
torque wrench.
Break off the flanks only when the clamping
screws have been fully tightened.
Correction loss due to insufficient fixation of the
implant head!
Never loosen the connection of the implant
head again, once it has been tightened.
Tighten the clamping screw only after every
WARNING
necessary correction measure has been per-
formed.
Damage to the implant caused by overtightening
of the clamping screw!
Always tighten the clamping screw with the
exact torque specified for this purpose.
WARNING
Implant head expansion caused by tightening of
the clamping screw without using the countering
instrument!
Always use the countering instrument when
tightening the clamping screw.
WARNING
Damage to the implant caused by applying the
repositioning instruments too high at the implant!
Always apply repositioning instruments (e.g.
distraction and compression forceps) below
the rod at the implant.
WARNING
Implant head expansion caused by derotation
without using derotation sleeves!
Always use derotation sleeves for rod derota-
tion.
WARNING
Damage to the implant caused by spondylolisthesis
reposition through the clamping screw!
Always use the rod persuader for spondylolis-
thesis reposition.
WARNING
Always use the special flank breaking forceps for breaking off the flanks.
If the screw head comes loose during a revision of the larger polyaxial
screws (∅ 7.5 mm or larger), remove the remaining screw component
with the screwdriver SW 3.5.
Inadequate fixation due to incorrect rod position!
Always position rods with hexagon and tip in
such a way that hexagon and tip are outside
the implant head.
WARNING
For tightening the locking screws of the cross connector, always use the
torque wrench and countering instrument intended for this purpose.
