4NCB® Proximal Tibia System – Surgical Technique
Introduction
The NCB PT (Non-Contact Bridging
for the Proximal Tibia) is an optimal
plate solution for the treatment of
complex fractures of the proximal tibia.
The system allows for polyaxial screw
placement (30°) with subsequent screw
locking. Before locking, the screws
can act as lag screws and be used for
fracture reduction; a benefit which
is not offered with standard locking
systems.
In the locked mode, NCB PT Plate late
acts as an internal fixator without
contact between the plate and the
bone surface reducing the risk of
periosteal blood supply impairment.
The surgical technique is based on
the well-known standard plate osteo-
synthesis technique which gives
to surgeon the feeling for bone quality
during drilling and tightening of the
screws. In the last step all screws can
be locked and made angularly stable.
The instrumentation includes a fully
radiolucent targeting device for a
minimally invasive surgical technique
(MIS).
Materials: NCB Plates and Screws are made
of Ti6Al4V, ISO 5832-3, ASTM F136
Blind screw insert
Implants are available with
2 or 3 proximal holes,
left and right. Plate length
varies from 5 to 9 shaft
holes for the 2-proximal hole
plate and between 3 and
13 shaft holes for the 3-proxi-
mal hole plate.

Plate Design
Two versions of the NCB PT Plate are
available: 2-proximal and 3-proximal
holes.
Due to the angular freedom of the
screws the whole plateau area can
be covered with both plates. The
2-proximal holes plate is recommended
when soft tissue coverage is a greater
concern.
The 3-proximal holes plate is recom-
mended when there is a higher concern
for supporting the tibial plateau
(e.g. severe intra-articular comminution).
Plate head has 6˚ posterior tilt to match
the lateral tibial contour.

Preoperative Planning
and Patient Positioning
Select the appropriate length and type
of the NCB PT Plate using X rays and the
X ray template (REF 06.01365.000).
Based on the fracture type and the
specific patient condition determine
the surgical approach (i.e., open
technique or MIS) to be performed.
Place the patient in a supine position.
Lower the contralateral leg slightly
to make sure that lateral and AP X ray
views can be obtained clearly.
Support the knee while allowing the
leg to move freely.
Note: Do not use the x-ray template with
the 3 hole length tibial NCB plate with 3
proximal holes (REF 02.02261.203 and

Open Technique
Incision
A lateral incision is recommended for
extra-articular and laterally based
type 41-B fractures, according to the
OTA classification.
For type 41-C fractures according to
the OTA classification with a complete
articular fracture, a straight antero-
lateral incision or short medial and
lateral incisions are recommended.
To facilitate fracture healing do not strip
the periosteum.
Fracture Reduction
Restore the articular surface (if needed)
and reduce the fracture prior to
inserting the plate. Bone fragments
can be secured with 2.0 mm K-wires
(REF 290.20.280). Make sure that
K-wires do not interfere with the future
location of the plate and screws.
Note: Check fragment position with an
image intensifier.
Optional: Bone Spacers
Two bone spacers can be used in
the diaphysis to avoid contact of the
plate with the bone surface reducing
the risk of periosteal blood supply
impairment.
The spacers are available in sizes
of 1 mm, 2 mm and 3 mm
(REF 02.0x150.311 to 313).
Note: Insert adequate bone spacers into
the plate before plate insertion using a
3.5mm hex screwdriver. Spacers are
single use only and they can be removed
after locking the screws.

Insertion of NCB PT Plate
Insert the plate (REF 02.02261.xxx)
between the anterior tibialis muscle and
the periosteum.
The plate should be placed as close
as possible to the cartilage.
Temporarily fix the plate proximally and
distally with 2.0 mm K-wires through
the small holes in the plate.
Check the plate position and the fracture
alignment with an image intensifier in
both planes. Make sure the leg axis has
been restored.
Note: The plate is anatomically shaped.
Do not bend or contour the plate to
avoid damage of the locking mechanism.
Insertion of NCB Screws
A maximum of thirty degrees of screw
angulation is allowed in all plate holes.
Use the NCB Drill Guide to avoid exces-
sive screw angulation with consequent
failure of the locking mechanism.
Note: The 4 mm NCB MotionLoc
Screws are also compatible with all
plates in the Proximal Tibia Plate System
except for the 3 hole length tibial NCB
plates with 3 proximal holes
(REF
02.02261.203 and 02.02261.303)**.
See Zimmer MotionLoc surgical technique
(REF 97-3161-002-00 or 97-3161-004-00)*
for more specific instructions.

Cancellous Screws
For the 5.0 mm cancellous screws (REF 02.0x152.xxx) use the NCB Drill
Guide 2.5 mm (REF 02.00024.010). To ensure correct use of the drill
guide, press the drill guide into the plate hole in a perpendicular
position and then tilt it into the preferred position. The drill guide
needs to be in constant contact with the bottom ring of the hole.
Use the 2.5 mm drill bit (REF 103.25.180) for the 5.0 mm cancellous
screws.
* 97-3161-002-00 is for countries where NCB MotionLoc screws are approved to be used with only NCB plates and 97-3161-004-00 is for countries where
NCB MotionLoc screws are approved to be used with both NCB as well as NCB Periprosthetic plates. See NCB MotionLoc package insert for approved plate/

14 NCB® Proximal Tibia System – Surgical Technique
Use the NCB Depth Gauge
(REF 02.00024.005) to determine
the appropriate screw length.
Insert NCB Cancellous Screws using
the NCB PT Hexagonal Screwdriver,
(REF 02.00024.124) and apply compres-
sion if needed. Cancellous screws are
partially threaded and can be used as
lag screws.
Depending on fracture type, in the
epiphyseal and metaphyseal areas,
screws should be tightened to reduce
the fracture and obtain close contact
between the plate and the bone in order
to buttress the fracture.
Note: Tighten the bone screws by
hand only.
Repeat this procedure to insert all the
necessary NCB Cancellous Screws.
It is recommended that the most
proximal cancellous screws be placed
parallel to the tibia plateau.
Check the fracture reduction, plate
position and the leg axis with an
image intensifier.
To secure the angular stability insert the
NCB Locking Caps (REF 02.03150.300)
on all the cancellous screws used. Tighten
the locking caps with the NCB Torque
Screwdriver, 6 Nm (REF 02.00024.021)
until a clicking sound is heard.
Note: Always use the torque screwdriver
to tighten the locking caps and make
sure the screwdriver is not tilted during
its usage. Failure to do so could damage
the hex drive and might complicate
extraction of the implant.
Remove the proximal K-wire.

Optional
Cannulated Cancellous Screws
NCB Cannulated Cancellous Screws
are self-drilling and self-tapping. These
screws can be precisely placed over
the NCB Guide Wire, 1.6 mm.
A cannulated drill bit can be used to
pre-drill hard cortical bone.
Insertion of the 1.6 mm NCB
Guide Wire
Use the NCB Drill Guide to avoid exces-
sive angulation of the cannulated
screws with consequent failure of the
locking mechanism.
For the 4.5 mm cannulated cancellous
screws (REF 02.0x158.0xx) insert the
NCB PT Drill Guide 3.3/1.6 mm
(REF 02.00024.192) into the NCB Drill
Guide 3.3 mm (REF 02.00024.111).
Press the drill guide into the plate hole,
tilt it in the preferred position and insert
the NCB Guide Wire with threaded tip
(REF 02.01362.116).
Note: use only the NCB Guide Wire
(REF 02.01362.116) 1.6 mm,
L = 190 mm.
Failure to do so misleads the screw
length measurement.
Use the NCB Drill Guides to avoid an inclination 30° when inserting
the NCB 1.6 guide wire
16 NCB® Proximal Tibia System – Surgical Technique
Insertion of the Cannulated
Cancellous Screws
Remove the NCB Drill Guide 3.3 mm
(REF 02.00024.111) and NCB PT Drill
Guide 3.3/1.6 mm (REF 02.00024.192)
and determine the screw length from
the measurement with the NCB PH/PT
Measuring Device (REF 02.00024.219)
along the NCB Guide Wire.
For hard cortical bone it is possible to
use the 3.3 mm NCB PT Cannulated
Drill Bit (REF 02.00024.233).
Note: use the 3.3 mm NCB PT Cannu-
lated Drill Bit (REF 02.00024.233)
only for the first lateral cortex, to make
sure that the NCB Guide Wire does
not fall out.
Use the cannulated hexagonal screw-
driver (REF 02.00024.120) to insert
the cannulated self-drilling screws over
the 1.6 mm NCB Guide Wire.
To achieve the final angular stability
remove the NCB Guide Wire and tighten
the locking cap with the torque
screwdriver 6 Nm (REF 02.00024.021)
until the clicking sound is heard.
Note: it is important to remove the NCB
Guide Wire (REF 02.01362.116) prior to
inserting the locking cap
(REF 02.0x150.300) because the axial
directions for the cannulated screws and
locking cap may be different.
Measure the screw length with the
NCB PH/PT Measuring Device
Insert the cannulated screw with the
hexagonal cannulated screw driver
NCB® Proximal Tibia System– Surgical Technique 17
Cortical Screws
Bicortical insertion is recommended.
For the 4.0 mm cortical screws
(REF 02.0x155.0xx) use the NCB Drill
Guide 3.3 mm (REF 02.00024.111)
with the 3.3 mm drill bit
(REF 02.00024.118).
In case of hard cortical bone tap the
cortex with the NCB Tap
(REF 02.00024.040). Remove the
NCB Drill Guide 3.3 mm when using
the NCB Tap.
Measure the screw length and
insert NCB Cortical Screw using the

MIS Technique
MIS is recommended for simple and/
or extra-articular fractures. An open
approach is recommended in the proxi-
mal area to restore the articular surface.
Plate Hole Numbering System
To target the correct plate holes there
is a numbering system on the targeting
devices (REF 02.00024.08x)
Screw holes in the proximal and meta-
physeal areas are indicated with Greek
letters (α, β, γ, δ and ε).
Screw holes in the shaft area are
indicated with Roman numbers (1 to 13
according to plate length).
Note: Do not use the MIS device with the
3 hole length tibial NCB plate with 3
proximal holes (REF 02.02261.203 and
02.02261.303)**.
Incision and Fracture Reduction
A lateral incision should start proximal
to Gerdy’s tubercle and should be
extended for about 50 mm distally.
Note: Incision length will vary according
to the type of fracture.
Reduce the fracture as described in the
open technique. Take care that K-wires
used to temporarily stabilize the fracture
do not interfere with the future plate
location.

22 NCB® Proximal Tibia System – Surgical Technique
Insert the tissue protection sleeve
Insertion of NCB Screws
in the Shaft
Make a stab incision to access the plate
hole and insert the tissue protection
sleeve assembly (REF 02.00024.090 to
093).
Screw the NCB PT Drill Guide
(REF 02.00024.091) into the plate and
then the NCB PT soft tissue protection
sleeve (REF 02.00024.090) into the
targeting device.
Remove the NCB PT Trocar and NCB PT
K-Wire Guide and insert the NCB PT
Drill Bit 3.3 mm (REF 02.00024.133)
when the 4.0 mm cortical screw is used.
Use the scale on the drill bit shaft
or the NCB PT Depth Gauge
(REF 02.00024.007) to determine the
appropriate screw length.
Alternative measuring of the screw
length with the NCB Depth Gauge
Drill the screw hole in the bone shaft
NCB® Proximal Tibia System– Surgical Technique 23
Remove the NCB PT Drill Guide and
insert the appropriate screw using
the NCB PT Hexagonal Screwdriver
(REF 02.00024.124).
Note: The screw is completely inserted
when the marker on the screwdriver
reaches the soft tissue protection sleeve.
Insert and tighten the locking cap
(REF 02.03150.300) with the NCB Torque
Screwdriver, 6 Nm (REF 02.00024.021)
until a clicking sound is heard.
Note: Always use the torque screwdriver
to tighten the locking caps and make
sure the screwdriver is not tilted during
its usage. Failure to do so could damage
the hex drive and might complicate
extraction of the implant.
Remove the NCB PT Soft Tissue Protec-
tion and insert the NCB Screw Marker
(REF 02.00024.077) to indicate that the
screw is placed and locked in the hole.
Repeat the described procedure to
insert additional screws.
Insert the screw in the bone shaft
Use the screw marker to indicate that the screw is inserted and
locked in the hole and proceed to insert additional screws
Insert the locking caps using the NCB Torque
Screwdriver to achieve 6 Nm
24 NCB® Proximal Tibia System – Surgical Technique
To place the most distal screw, exchange
the NCB Stabilization Bolt with the
NCB PT Drill Guide and protection sleeve
and follow the procedure described
above.
Unscrew the connecting bolt to remove
the targeting device.
Note: when using the long plate (i.e.
13 holes) the last three distal screws
may interfere with the Superficial
Peroneal nerve. Therefore, it is recom-
mended a slightly longer stab incision
to visualize and avoid damage to the
Superficial Peroneal nerve.
Implant Removal
To remove the NCB PT Plate, first remove
all the locking caps. Then loosen all the
NCB Bone Screws without completely
removing them (this prevents rotation of
the bone plate when removing the last
screw). Then, completely remove all the
bone screws.
Note: make sure that the tip of the
NCB PT Screwdriver (REF 02.00024.124)
is correctly placed in the hex drive
of the locking caps and/or NCB Screws.
Failure to do so could damage the
hex drive and complicate the extraction
of the implant.
Removal Tips
Re-assemble the NCB Targeting
Device to remove the shaft screws
if the MIS approach was used
for implantation. The targeting device
ensures that the axial direction used
during implantation is considered.
In case of difficulties in loosing the
NCB Screws, tighten the screws slightly
before loosening them.
Take care to avoid damage
of the Superficial Peroneal
nerve when using long plates
Remove the NCB Stabilization
Bolt and insert the NCB Protection
Sleeve to insert the most distal
cortical screw
