SLIMPLICITY ANTERIOR CERVICAL PLATE SYSTEM OVERVIEW
®
The Slimplicity Anterior Cervical Plate System offers one
of the slimmest plates available with an easy to use locking
mechanism that facilitates visual locking confirmation.
Large graft windows have been incorporated to provide
unimpeded graft site and end plate visualization. The large
array of variable and fixed screw options accommodate
semi-constrained, constrained and hybrid philosophies,
while the plates are pre-contoured to address varying
patient anatomy in single and multi-level constructs.
Indications
The Slimplicity Anterior Cervical Plate System is indicated
for use in temporary stabilization of the anterior spine from
C2 to T1 during the development of cervical spinal fusions
in patients with: degenerative disc disease (DDD)
(as defined by neck pain of discogenic origin with
degeneration of disc confirmed by patient history and
radiographic studies); spondylolisthesis; trauma (including
fractures or dislocations); spinal tumors; spinal stenosis;
pseudarthrosis; and failed previous fusions.
Please refer to package insert (LBL-IFU-005) for complete
system description, indications and warnings.

SURGICAL TECHNIQUE
1. Patient Positioning and Approach:
The patient is placed on the operating room table in
the supine position with the head in slight extension
and slight rotation opposite the side of incision. After
decompression and interbody grafting procedures
have been completed, remove all anterior osteophytes
to provide a contoured contact surface for optimum
plate positioning.
2. Plate Selection:
When selecting the Plate size that best fits the anatomy,
it is important to know that the length of the Plate is
based on the distance between the ends of the Plate.
The Plate should not extend over the adjacent disc
spaces.
3. Plate Contouring:
The Slimplicity Anterior Cervical Plate is precontoured with lordotic curvature to minimize intraoperative contouring. If the lordotic curvature of the
Plate needs to be modified, the Plate Bender may
be used for contouring. The Plate should not be
contoured through the locking mechanism as it
could become damaged.
®
4. Plate Positioning:
Position the Plate over the vertebral bodies to
be instrumented using a plate holder. Confirm the
Plate is properly aligned in mediolateral and
caudocranial position.
6
5. Temporary Pin Placement:
Plate position can be temporarily fixed using the
Fixation Pin and Bone Screw Driver. The Temporary Pin
can be inserted through any of the screw holes in the
Plate and provides stability during Screw placement
(Figure 5).
6. Preparing Screw Hole:
In preparing the screw hole, the Awl may be used to
create a pilot hole. The Awl is placed in the desired
screw hole position with up to 14˚ of angulation. Press
and rotate the Awl through the Plate and into the bone
until the depth has bottomed out against the Plate. The
Awl will provide a pilot hole up to a depth of 10mm
(Figure 6). If preferred, the Drill Guide (fixed or variable
depending on Screw choice) and Drill can be used to
create the screw hole. Attach the Drill Guide to the
Plate and drill the screw hole (Fixed Drill Guide if Fixed
Screws are desired or Variable Drill Guide if Variable
Screws are desired). The Drills are provided in 12, 14,
and 16mm lengths with corresponding Drill Guides in
both variable and fixed positions (Figures 7 and 7a).

7. Screw Insertion:
The self-tapping, self-drilling Bone Screws are
available in 12, 14, 16, and 18mm lengths in both
4 and 4.5mm diameters. All length and diameter Bone
Screw options are available in a fixed and variable
head design. Bone Screw lengths measure from under
screw head to point. The Bone Screws selected for
implantation are inserted using the ACP Bone Screw
Driver (Figure 8). Insert the Bone Screw into the
vertebrae to be instrumented until it rests firmly inside
the plate screw hole (Figure 9). This will enable the
Locking Mechanism to be engaged. Repeat the Screw
insertion procedure for each screw hole position
within the Plate.
Figure 8
8. Locking Mechanism:
Once the Bone Screws have been properly seated,
positioned, and tightened, the Locking Mechanism can
be rotated to secure the seated Bone Screws within the
construct. Insert the ACP Locking Tool between the two
green rivets and rotate 360˚ until the rivets cover both
screw heads (Figure 10). Do not rotate rivets more than
two times as this will weaken the Locking Mechanism.
Secure all Bone Screws with the Locking Mechanism
(Figure 11). If desired the ACP Lock/Unlock tool can
be used to lock the green rivets individually. Turn the
rivet until it is fully engaged as pictured in Figure 11.

9. Closure:
After visual and radiographic confirmation of Plate,
Screw, and bone graft placement, the closure process
can proceed.
The Slimplicity Anterior Cervical Plate System surgical
technique is a general guide for instrumentation. The
surgeon should be familiar with anterior cervical fusion.
®
10. Screw Removal:
Figure 12
If needed, the Bone Screws can be removed using the
Lock/Unlock Tool. The Locking Mechanism is rotated
back to its unlocked position (Figure 12). Once the
rivet has been rotated the Screws can be removed
from the construct.
