STEP 2, OPTION 1B
Band Advancement
•
When the band is visible at the cephalad margin
of the lamina, hold and stabilize the tip of the
band with the
bengolea forceps
.
•
To avoid pushing the band into the dura, maintain
upward pressure against the anterior aspect of the
lamina by pulling up on the tip of the band while
advancing the malleable leader under the lamina
until its ends are of equal length.
Note:
Periosteal elevators are not used to prepare
laminar anatomy prior to band passage. Band passers
are not used to pass the band under the lamina. Do not
twist the band during band passage maneuvers and
take care when passing the band near the thecal sac.
STEP 2, OPTION 2A
Transverse Process Band—
For Use in Adult Patients
•
Requires Universal Clamp Instrument Kit
SNA027-0008-PL.
•
Transverse process band passage is warranted
where additional bony fixation is desired.
Passage Around Transverse Process
•
To pass the band around the transverse process,
first use an elevator to create a pathway for the
band. Introduce the elevator from the cephalad
margin of the transverse process, holding the
handle lateral to the spine.
•
With a rotating motion, turn the elevator
around the transverse process.
