• Lengths: 25-55mm
• Inner diameter: 3.7mm
• Outer diameter: 5.5mm
• Cancellous thread pitch: 3.2mm
• Cortical thread pitch: 1.6mm
• Self-drilling and self-tapping screws
If the posterior aspect of the
cage is at max expansion, the
greatest possible lordosis
would be 14° for the Small
cage, 15.5° for the Medium,
and 16° for the Large cage.

Access
Catalyft™ LS expandable
The
interbody system can be used
with an OLIF51™ procedure or an
ALIF procedure, depending upon
the surgeon’s preference and
anatomical considerations. Refer to
the appropriate procedural
surgical technique for access and
disc preparation instructions.

Templates/Distractors
After the disc space has been
prepared and any osteophytes have
been removed, Templates matching
the cage in a collapsed state are used
to identify the cage's footprint and size
matching the initial anatomy.
Distractors can be used sequentially
to stretch the soft tissues and optimize
the segmental correction by expansion
of the cage in situ. A/P and lateral
fluoroscopy can also be used to
confirm the appropriate cage size and
positioning.
Note
Due to expansion capability of the
cage, the template may fit loosely in
the disc space.

Cage attachment
After the appropriate cage has been
determined, attach the corresponding
cage to the Inserter. Insert the
Lordosis/Parallel Shaft 5NM 98100002
into the Inserter by pressing down on
the release button on the handle and
fully inserting the shaft into the cannula
of the Inserter until the expansion
indicator is in the "Parallel" expansion
state. Attach the cage to the Inserter
by threading the Inserter into the
female thread of the cage by using the
thumbwheel on the Inserter
and advancing the threads until the
cage is firmly attached to the cage.
When inserting the cage, the Inserter
should be in the parallel expansion
state.
Note
The Inserter can be attached
independently of the orientation of the
cage or handle.
Ensure the cage is in collapsed state
prior to implantation.

Pre-implantation graft delivery
Once the correct cage has been
attached to the Inserter, the Bone Graft
Loader can be used to pre-pack the
cage with autogenous bone graft and/
or allograft bone graft comprised of
cancellous and/or corticocancellous
bone, and/or demineralized allograft
bone with bone marrow aspirate. If
using Grafton™ DBF Inject, hydrate the
DBF with BMA according to the mixing
instructions in the Grafton™ DBF Inject
instructions for use.
Note
Refer to the Grafton™ DBF Inject IFU
for handling and preparation steps.
