SUBSEQUENT LEVEL AUGMENTATION
Place the existing cannula and cement reservoir into the next
alignment guide and repeat the procedure described above.
Repeat for each desired vertebral level, ensuring that
cement flow has stopped between each level.
If an additional cement package is needed, remove the
existing cannula and attach a new cannula.
If additional cement is needed beyond its working time,
dispose of the cement and cannula. Use a new cannula and
mix a new dose of cement for the remaining screws.
Optional Step: The plunger can be used to pass the cement
remaining in the cannula into the screw after the cement
reservoir has been emptied. Detach the reservoir from the
cannula and proceed with plunger insertion.
REMOVAL OF ALIGNMENT DEVICES
After the cement introduction, the alignment devices can
be unthreaded from the screw head.
RESIDUAL CEMENT REMOVAL
After use, the Alignment Devices must be visually inspected
for any cement.
If cement remains in the Alignment Device, insert the Stylet
through the Alignment Device and rotate to ensure any
cement is removed.
Insert the Mini-Stylet into the threaded tip of the
Alignment Device.
If cement remains in the device, repeat cleaning steps above
or return it to DePuy Synthes Spine.
FIGURE 25
NOTE:
After cement injection, no torsional movement
must be applied to the screw throughout the cement
setting time outlined in the respective package insert.
At the end of the case, any opened cannulas must be
discarded.
