Contour rod ex-situ

►
For ex-situ rod contouring, place the flexible rod template SZ267SU in
the head of the screws or hooks and bend it according to the corrected
spine.
►
Carefully remove the rod template so it is not incorrectly repositioned,
and use it for reference when bending the rod ex-situ.

WARNING
Danger of injury from damage (breakage) of the rod if bent incor-
rectly!
Rod cannot be inserted into the tube!
Rod cannot be fastened!
►
Avoid severe rod bending in the region of the pedicle screw or
hooks.
►
Only bend rod with provided rod bending instruments.
►
Do not bend rod multiple times at the same location.
►
Do not bend rod back.

Adjust desired bending radius on the french rod benders e: pull rotary
knob a and set the desired radius by turning
►
Place rod b between rotary knob a and the two rollers c.
►
Bend rod b to the desired radius by actuating the handle d of the
french rod benders SZ270R.
Note
The rod b has an orientation line that facilitates the alignment of the rod
during the bending process.
Note
In addition, the rod grippers 16 or rod holding forceps SZ272R could be
used to prevent undesired rod rotation during the bending process.
►
To prevent undesired rod rotation during the bending process, use the
additional rod grippers 16 or rod holding forceps SZ272R.
3.7.2
Rods may be contoured using the sagittal rod benders left 18 (SZ342R)
and right 19 (SZ343R), which also allow for small radius bending.

►
To contour the rod, slide the rod into the desired hole of each sagittal
rod bender.
Note
The sagittal rod benders have two sets of holes, one set straight through the
shafts and one set at an angle through the shafts to allow for multiple ex-
situ bending curves.

►
Grip the most distal portions of the sagittal rod benders for enhanced
mechanical advantage during contouring.
►
By levering the sagittal rod benders the rod is bent according to the
desired contour.
