NOTE:
The alignment device MUST be used for each
screw intended for cement augmentation. Without the
alignment device, there is a potential risk of cannula
breakage. Use of the alignment device will prevent
undue stress from being applied to the cannula.
NOTE:
If a biopsy is completed prior to screw
placement, care must be taken not to place the tip of
the biopsy needle beyond the desired location of the
screw tip in order to reduce the risk for cement
leakage or extravasation.
NOTE:
Fenestrated screws should NOT be placed
bicortically. It is very important not to breach the pedicle
wall or anterior cortex of the vertebral body to avoid
cement extrusion into the retroperitoneal space. Use
appropriate imaging techniques, such as fluoroscopy, to
confirm screw placement.

If enhanced fixation in the pedicle and the vertebral body is
desired, the EXPEDIUM VERSE Fenestrated Polyaxial Screw
provides a fenestrated screw shank will accommodated the
delivery of cement.
Reference the prior surgical steps above for pedicle
preparation and screw insertion.
ASSEMBLY OF THE ALIGNMENT GUIDE
Check that the alignment device and alignment sleeve are
clear of any cement from prior use.
Insert the alignment device into the alignment sleeve and
push the two pieces together until you hear a click.
ALIGNMENT OF THE SCREW
Align the tabs of the alignment sleeve with the rod slot in the
screw head, ensuring that the soft tissue does not impinge
on the connection of the alignment sleeve to the screw head.
Thread the assembled alignment guide into the screw head.
This will align the screw shank to the screw head.
Confirm that the alignment device is fully seated by checking
that the alignment guide and the alignment sleeve are fully
seated (See detail).
Repeat this step for each screw intended for
cement augmentation.
