The dual-opening pedicle screws have the same head as
the pedicle, lamina and angled hooks. The following
handling instructions hence refer to both the pedicle
screws and all three hook types (termed “implants” in
the following).
1. Attach handle to stick
Press the knurled release button on the upper end of the
handle (388.622), and simultaneously attach the hook
and screw holder with hexagonal 4.0 mm (388.612)
(also termed the ”stick”) to the handle.
2. Pick up implant
Pick up the dual-opening implant with the stick and
handle by rotating the release button on the handle.
3. Release handle from stick
Insert the implant. To release the handle from the stick,
press the release button on the handle.
