CAGE INSERTION

Markers
STEP 9
Prior to cage insertion, bone graft material may be
placed anteriorly or contralaterally.
Insert the cage into the interbody space with successive
impactions on the cage holder, parallel to the endplates.
A non-parallel insertion may weaken the end plates due
to conflict with the cage.
Take care to position the cage as close as possible to its
final position.
Confirm proper implant placement using fluoroscopy
