HONOUR® Spacer System - TLIF and tPLIF
The HONOUR® Spacer System is a collection of radiolucent
cage devices constructed of medical grade
polyetheretherketone with tantalum markers as described in
ASTM F-2026 and ASTM F-560. The TLIF and TPLIF implants
are comprised of various heights and footprints to
accommodate individual patient anatomy and to maximize
bone graft material volume.
Following adequate general anesthesia, the patient is placed in
the prone position on a radiolucent spine table (Fig. 1).
Particular attention is applied to the positioning of the head and
extremities to lessen the risk of ocular and nerve compression.
EXPOSURE OF OPERATIVE LEVEL(S)
Identify the affected level(s) using fluoroscopic imaging and
palpation of the targeted anatomy (Fig. 2). Access the
operative site using preferred instruments. Tissues should be
retracted enough to allow for exposure and visualization of the
targeted disc space. Insert a marker into the disc(s) to confirm
the correct operative level(s) using a lateral radiograph (Fig. 3).
NOTE: HONOUR® TLIF/tPLIF Interbodies are indicated for use
at up to two contiguous levels in the lumbar spine, from L2-S1.
Perform a complete discectomy using preferred surgical
instruments. Pituitaries, cup curettes, rongeurs and interspace
shavers may be used to remove the disc material (Fig. 4). If
there is significant disc space collapse, a complete discectomy
may not be possible until disc space distraction is
accomplished. The main goal of this step is to provide entry to
the disc space for distraction with minimal or no nerve root
