2. Position pedicle hook
Using the stick, pick up a pedicle hook from the set, as
described on page 4.
Note:
Use a front-opening hook if a rod connector is
needed.
Insert the hook positioner (388.631) into the positioning
hole of the hook, and ease the pedicle hook into the
previously prepared seat. Ensure that the pedicle hook is
snug around the pedicle by pushing the hook positioner
axially and laterally. The pedicle hook should not move.
Gently tap the hook positioner with a hammer to firmly
seat the hook.
Remove the hook positioner and the handle. The stick
remains attached to the hook.
3. Drill hole for screw Ø 3.2 mm
To anchor the pedicle hook to the pedicle, a screw Ø 3.2
mm can be inserted through the hole at the back of the
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.
Warning:
Do not start the power drill if the bit does
not hit bone after passing through the drill sleeve.
