STEP 11
Manually push the double impactor to advance the
impactors and bring the tips of the plates in contact with
the vertebral endplates.
Caution:
Check the alignment of the cage holder with
the cage before starting impaction of the plates. If the
cage and the cage holder are misaligned, the plates won't
be able to follow their predefined trajectory, resulting in
contact with the cage.
Impact the double impactor with a mallet until the
mechanical stop is reached while holding the cage
holder handle firmly to prevent advancement of the
cage
(Figure 11a)
.
Caution:
Once the impactors have reached the
mechanical stop, impaction with the mallet must be
stopped. Plates are inserted and locked inside the cage.
Use fluoroscopy to check proper plate positioning
