Pedicle hook positioning
3. Drill hole for Ø 3.2 mm screw
To anchor the pedicle hook to the pedicle screw, a
Ø 3.2 mm cortical screw can be inserted through the
hole at the back of the pedicle hook.
Use a three-fluted drill bit Ø 2.0 mm (315.190) together
with the USS drill sleeve 2.0 and an oscillating drill to
drill the screw hole. The drill sleeve consists of two com-
ponents, the drill sleeve (388.581) and the handle
(387.060). These two components must be screwed
together before use. Advance the tip of the drill until it
passes through the vertebral endplate.
Warning:
Do not start the power drill if the drill does
not hit bone after passing through the drill sleeve.
4. Determine screw length
Remove the drill sleeve and determine the depth with
the Depth Gauge for Screws Ø 1.5 to 2.0 mm (319.060).
5. Insert Ø 3.2 mm screw
Pick up an appropriate length USS Screw for Pedicle
Hooks using the Holding Sleeve (314.060) using the
Holding Sleeve (314.060) and Screwdriver (314.070) and
insert it into the previously prepared drill hole. The pedi-
cle hook is now attached to the pedicle and the
endplate.
