Product Overview
The Zimmer Natural Nail System is a
system of intramedullary nails, screws,
instruments and other associated
implants that are designed to provide
stable internal fixation for fractured long
bones. The nails have been designed
for specific applications to help restore
the shape of the fractured bone to its
natural, pre-injured state.
The Tibial Nail is designed to help treat
various fractures of the tibia. Screws are
placed through the nail to secure the
implant in place and maintain length and
alignment while healing occurs. The nail
has multiple screw holes in the proximal
body to allow surgeons to address
different fracture types. The proximal slot
allows for compression or dynamization
across a fracture.
A choice of lengths and diameters
is available to match the individual
anatomy of the patient.

Precision instrumentation is provided
to help implant the nail. Many of the
instruments and implants feature
color coding to help the surgical team
use the system, easily and efficiently.
Certain universal instruments are not
color coded. The color coding system is
referenced in the technique. A wall chart
(97-2495-003-00) is also available to
help explain the color coding system.
The technique is written to explain use
of the SUPRAPATELLA TARGETING GUIDE
which should be used when the knee is
in extension.
Indications
The Zimmer Natural Nail System is
intended for temporary fracture fixation
and stabilization of the bone.
Indications for the tibial nails include the
following:
Compound and simple shaft fractures
Proximal, metaphyseal and distal shaft
fractures
Segmental fractures
Comminuted fractures
Fractures involving osteopenic and
osteoporotic bone
Pathological fractures
Fractures with bone loss
Periprosthetic fractures
Pseudoarthrosis, non-union, mal-
union and delayed union
Surgically created defects such as
osteotomies
When this device is implanted using a
Suprapatella surgical approach, all of
the above indications apply with the
exception of Periprosthetic Fractures.
Contraindications
A medullary canal obliterated by a
previous fracture or tumor
Bone shaft having excessive bow or
deformity
Lack of bone substance or bone
quality which makes stable seating of
the implant impossible
All concomitant diseases that can
impair the functioning and the
success of the implant
• Infection
Insufficient blood circulation
Skeletally immature patients
WARNING: This nail should only be
used to treat a periprosthetic fracture
if the in situ device is firmly fixed and
if the Suprapatella surgical approach is
not being used for implantation. When
treating a periprosthetic fracture, the
nail should be positioned so that it does
not come in contact with the in situ
device.

Surgical Technique
Preoperative Planning
Preoperative planning is recommended
before beginning the surgical procedure.
A/P and Lateral x-rays of the injured tibia
should be taken preoperatively and
evaluated for length, canal size and
implant suitability. A/P and Lateral x-rays
of the contralateral uninjured tibia can
also be taken preoperatively to provide
insight into the characteristics of the pre-
injured tibia.
Patient Positioning
The patient should be positioned in the
supine position. The positioning should
allow the knee of the injured leg to be
placed in at least 10°-20° of flexion. Use
e.g. blankets, custom foam devices or
sterile bumps to support this position.
The use
of a fracture table can be beneficial
to help
reduce fractures as well as to
facilitate intraoperative imaging with a
C-arm. The C-arm should be placed to allow
for imaging of the tibia in both planes
along the entire length of the bone.
Drape the patient appropriately to allow the
surgeon to work from the knee to the foot.
Reduction
It is critical to achieve anatomic
reduction before beginning any of the
steps to place the IM Nail. Traction
should be used as necessary to help
achieve fracture reduction. Several
instruments are available to assist in
fracture reduction including clamps,
ball spike pushers and Steinman pins,
femoral distractors or external fixation
systems.
Starting Point Location
The starting point for the nail is located
on the shelf of the tibia, just medial to the
Lateral Intracondylar Eminence (Fig. 1).
Avoid an excessively medial start point
to minimize potential for intra-articular
damage. With the knee in full extension,
make a 2cm longitudinal skin incision
either starting at the pole of the patella
or starting 1cm superior (corresponds
to one finger breadth) to the pole of the
patella.

Fig. 5
Fig. 6
The deep incision, also longitudinal,
splits the quadriceps tendon in its
midsubstance, just above its insertion
into the patella and enters the knee joint
through the suprapatellar pouch.
Blunt dissection can be used to loosen
the patella in the suprapatellar pouch,
allowing the patella to lift off. Displace
the patella anteriorly.
Assemble the ENTRY CANNULA with the
corresponding blue ENTRY CANNULA
HANDLE (Fig. 2). Orient the laser mark
on the handle to any laser mark on the
cannula.
Insert the CANNULATED TROCAR into the
handle assembly. Push down on and lock
the inner instruments to make sure that
everything is properly put together (Fig. 3).
NOTE: Inspect the ENTRY CANNULA as it
may become damaged, bend or chipped
with excessive prior reaming and
insertion of any other instruments. Any
flaws in the tube can lead to damage of
the surrounding tendons and tissues.
CAUTION: Do not use ENTRY CANNULA
without trocar properly assembled
or directly with the STARTING POINT
MODIFIER attached.
Insert the handle assembly through the
incision into the knee joint so that it
glides between the articular surface of
the patella and the trochlea of the distal
femur and rests securely in this groove,
while the patella is displaced anteriorly.
When the CANNULATED TROCAR reaches
the surface of the tibia stop pushing
down the handle assembly.
NOTE: The knee must remain in
extension or slightly flexed once the
handle assembly has been inserted.
Pin Insertion
Place the 3.0mm PIN through the
CANNULATED TROCAR and advance to
the anterior surface of the tibia (Fig. 4).
Slight adjustment of the knee flexion
(between 10°-20°) will provide the ideal
radiographic location for the starting
point and insertion of the PIN into the
tibia.
Use the C-arm to visualize the pin’s
position from A/P and Lateral views. The
PIN should be inserted at the identified
point heading slightly posterior into the
medullary canal.
Drive the pin through the starting point
into the center of the medullary canal.
Adjustments to the PIN location can be
Fig. 3
Fig. 2
Fig. 4
made by replacing the CANNULATED
TROCAR by the STARTING POINT
MODIFIER (Fig. 5). Rotate it to place a
second PIN while the first PIN remains
in place. Distance between the two
pins is 4mm. After correct placement
of the second PIN the initial PIN and
the STARTING POINT MODIFIER can be
removed.
Once the ENTRY CANNULA is in place
and the PIN position is verified, the
CANNULATED TROCAR can be removed
from the surgical field (Fig. 6). If needed,
a standard suction device can be
attached to the ENTRY CANNULA.
Place the 8mm ENTRY REAMER over
the PIN, through the ENTRY CANNULA
and down to the bone (Fig. 7). Using
fluoroscopy, ream an entry portal into
the proximal tibia to the metadiaphyseal
flare. The PIN and the ENTRY REAMER
should not reach the posterior cortex.

Fig. 9
Fig. 8
Fig. 7
Remove the ENTRY REAMER.
Alternatively, a STRAIGHT AWL or a 12mm
ENTRY REAMER can be used to find the
entry
point and create the entry portal (Fig. 8).
NOTE: Do not use the STRAIGHT AWL
with power. Always attach the MODULAR
HANDLE to perform the opening of the
IM canal.
Only nails up to 12mm may be used
with this technique. If an 8mm entry
reamer was used for proximal reaming,
then use the 12.0mm ENTRY REAMER to
finish preparing the proximal tibia for
the proximal portion of the nail (sizes
8-11mm). If the bone is especially
dense, it may be necessary to over-ream
the proximal tibia by 0.5 to 1.0mm to
accommodate the proximal portion of
the nail. The groove in the reamer flutes
indicates the final position of the top of
the nail. In addition, the c-arm should
be used to visualize the depth of the
reamer in the proximal tibia. Care should
be taken to keep the reamer in line with
the shaft of the tibia to avoid reaming
through the cortex of the tibia.
Remove the pin.
Place a 3.0mm x 100cm BALL TIP GUIDE
WIRE or TEAR DROP GUIDE WIRE through
the ENTRY CANNULA into the medullary
canal all the way into the distal tibia. To
aid in manipulation, bend the tip of the
GUIDE WIRE at about a 100 angle 5cm
from the end.
CAUTION: If the GUIDE WIRE is bent
shorter than 5cm from the end of the
wire and/or more than 10 degrees it may
be difficult to remove from the nail. If
the wire becomes lodged inside the nail,
utilize the GUIDE WIRE GRIPPER and
mallet to remove the guide wire from the
nail.
Fluoroscopy can assist you in guiding
the GUIDE WIRE past the fracture site. If
you plan to ream the canal of the tibia,
the GUIDE WIRE should be centered and
embedded in the distal tibia at the level
of the distal epiphyseal scar using the
GUIDE WIRE GRIPPER and a MALLET (Fig.
9). Care should be taken not to drive the
wire through the ankle joint.
Assemble the two piece NAIL LENGTH
GAUGE. Slide the tube portion of the
gauge over the 3.0mm x 100cm GUIDE
WIRE until the tip of the tube is at the
level of the entry point (confirm position
using fluoroscopy)( Fig. 10).
The proximal end of the GUIDE WIRE
indicates the
length of the wire in the
canal (Fig. 11).
When determining nail
length, consideration should be taken as
to how deep the nail will be inserted into
the tibia based upon the desired location
of the proximal screws. A RULER is also
included in the set which can be used to
radiographically determine nail length.
If a 70cm GUIDE WIRE is used, measure
the length of the canal by sliding only the
half of the NAIL LENGTH GAUGE that is
etched with length measurements to the
level of the entry point. The proximal end
of the 70cm GUIDE WIRE will indicate the
length of the wire that is in the canal.

Reaming
Attach a standard suction device to the
ENTRY CANNULA to remove reaming
debris from the knee joint.
Insert the reamer over the GUIDE WIRE
through the ENTRY CANNULA. Start with
a small reamer. Increase the diameter of
the reamer by 0.5 - 1.0mm depending
on the amount of resistance felt while
reaming.
NOTE: If the reamer head gets stuck in
the IM canal or interferes with the ENTRY
CANNULA, tilt the ENTRY CANNULA
HANDLE to a anterior-inferior position
to re-align the reamer head and ENTRY
CANNULA (Fig. 12).
The GUIDE WIRE PUSHER can help
prevent the GUIDE WIRE from coming out
of the tibia during reaming. When cortical
chatter occurs, stop reaming. Choose a
nail that is 1.0 – 1.5mm smaller than the
last reamer used. The proximal diameter
of nails equal to or smaller than 11mm
in diameter is 11mm. For nails 11mm
and larger in diameter, the diameter of
the nail is constant. If a nail smaller than
11mm is to be used, be sure to ream the
proximal portion of the bone to 11.5mm
to accommodate the proximal portion of
the nail.
NOTE: The ENTRY CANNULA allows
reamers up to 13.5mm to go through.
Do not use a larger reamer. Therefore
nails with a diameter of 13mm or 14mm
can’t be utilized with the suprapatella
instrumentation.
NOTE: If the GUIDE WIRE becomes
lodged within the reamer, use the GUIDE
WIRE PUSHER to push the GUIDE WIRE
back into the IM canal.
Nail Assembly and Insertion
The color code for the tibial nail is
YELLOW. Ti-6Al-4V alloy nails, the
SUPRAPATELLAR TARGETING GUIDE and
the CONNECTING BOLT all have yellow
colors and the word YELLOW etched on
them. Place the appropriate CONNECTING
BOLT (Suprapatella) through the barrel
of the LONG TARGETING GUIDE HANDLE.
Begin threading the CONNECTING BOLT
(by hand or using the CONNECTING BOLT
INSERTER) into the proximal portion of
the nail. Orient the nail so that the distal
portion of the nail angles anterior, the
same direction as the TARGETING GUIDE
HANDLE (Fig. 13).
Fig. 12

Fig. 14
Fig. 15
Slots in the top of the nail will match
tabs on the TARGETING GUIDE HANDLE to
help orient the nail correctly. Completely
tighten the CONNECTING BOLT to secure
the nail to the guide (Fig. 14). The arrow
on the nail will line up with the arrow on
the barrel of the guide when the nail is
correctly aligned.
Attach the TARGETING MODULE to the
TARGETING GUIDE HANDLE. Use a screw
cannula, drill sleeve and drill bit to verify
that the holes in the guide target the
holes in the nail. Remove the TARGETING
MODULE BEFORE inserting the nail.
Insert the NAIL over the GUIDE WIRE with
the arm of the guide facing anterior.
Monitor the progression of the nail down
the canal using the C-arm, especially as
the nail is passing through or near the
fracture site (Fig. 15).
NOTE: Before inserting the nail, the
ENTRY CANNULA has to be removed as
the nail will not pass through it.

If the nail does not pass down the canal
easily, attach the IMPACTION HEAD to
the TARGETING GUIDE HANDLE. Using the
MALLET, impact gently on the IMPACTION
HEAD (Fig. 16). Do not impact when the
MODULE is attached to the IMPACTION
HEAD. Verify that the CONNECTING BOLT
is tight while impacting. Do not impact
on any other portion of the TARGETING
GUIDE HANDLE or MODULE as this may
break the guide or cause it to lose its
accuracy. If the nail will not advance with
impaction, remove the nail and ream the
canal to a larger diameter at additional
0.5 mm increments or consider using a
smaller diameter nail. Place the top of
the nail in line with or below the surface
of the tibia, depending on its position
relative to the expected screw location.
Care should be taken to not pry on the
handle as this may cause damage to the
instrumentation.
Remove the GUIDE WIRE from the nail
using the GUIDE WIRE GRIPPER (Fig. 17).
If possible, remove the GUIDE WIRE
before fully seating the nail, if desired.

Retighten the CONNECTING BOLT to
the nail.
Attach the TARGETING MODULE to the
TARGETING GUIDE HANDLE (Fig. 18).
Select the screw holes that will be used
in the nail. Insert HOLE INDICATORS in
the holes in the TARGETING MODULE that
will NOT be used.

Proximal Screw Placement
All of the screw holes in the tibial nail
allow for standard locking or fixed angle
locking. To achieve standard locking,
choose a PARTIALLY THREADED SCREW.
To achieve a fixed angle construct,
choose a FIXED ANGLE SCREW.
Instruments that are specific to the
tibia nail are marked in YELLOW. The
instruments needed to place screws
through the proximal portion of the nail
are color coded ORANGE/ORANGE. These
instruments are placed through holes in
the targeting guide which are color coded
ORANGE. The chart below details the
color coded instruments that are used to
target and place screws.
Slide the TROCAR into the SCREW
CANNULA. Slide the SCREW CANNULA
through one of the selected holes in the
TARGETING MODULE. Dissect through
the tissue down to the bone to make a
path for the SCREW CANNULA (Fig. 19).
Advance the SCREW CANNULA until the
tip of the TROCAR is against the bone
(Fig. 20).

Remove the TROCAR. Insert the 4.3mm
DRILL SLEEVE through the CANNULA
down to the bone. Place the 4.3mm
DRILL BIT through the DRILL SLEEVE.
Before the DRILL BIT contacts the bone,
start the drill. Advance the spinning
DRILL BIT through the bone bicortically.
Use fluoroscopy to verify the appropriate
location of the DRILL BIT in the bone.
With the DRILL BIT in place and the DRILL
SLEEVE pressed against the bone, the
length of screw needed is indicated by
the etch marks on the DRILL BIT where
it exits the SCREW CANNULA (Fig. 21).
The tip of the drill should be no more
than 5mm through the far cortex of the
bone to reduce the risk of complications
associated with screw protrusion.
(Alternatively, the DRILL BIT and DRILL
SLEEVE can be removed and the SCREW
DEPTH GAUGE used to measure the
length of screw.)
Remove the DRILL BIT and DRILL SLEEVE.
Place the appropriate length 5.0mm
screw (color coded RED) through the
SCREW CANNULA into the bone (Fig. 22).
Using the screwdriver, advance the screw
to achieve bicortical purchase (the screw
head should sit on the near cortex of the
bone). The screws are self tapping so
tapping should not be necessary (Fig.
23).
If using the CAPTURED SCREWDRIVER,
place the appropriate screw on the
3.5mm HEX and tighten the screw to the
CAPTURED SCREWDRIVER by turning the
knob next to the handle clockwise.
CAUTION: If using the CAPTURED
SCREWDRIVER, do not torque the
CAPTURED SCREWDRIVER beyond the
calibration line next to the handle.
CAUTION: Do not drive the screws into
the bone under power, as damage to the
bone, screws and nail could result.
Note: Do not overtighten the screws.
Repeat this technique to place
additional proximal screws as necessary.

Distal Targeting – Freehand
Technique
8.3mm nails utilize a 4.0mm screw
(3.3mm drill bit) distally. These items are
color coded WHITE.
9.3mm and larger diameter nails use a
5.0mm screw (4.3mm drill bit) distally.
These items are color coded RED.
NOTE: There is no color indication on the
screw itself. Screw packaging and the
screw case contain color coding to help
identify the screw size.
Insert the appropriate diameter
FREEHAND DRILL BIT into the DISTAL
TARGETING WAND. Finger tighten the SET
SCREW. Position the C-arm in order to get
a lateral view of the distal tibia. Adjust
the angle of the C-arm so that the hole
through the nail appears as a perfect
circle on the monitor. Bring the tip of the
drill bit to the skin and use the C-arm to
center it over the hole that you desire to
place a screw through (Fig. 24).
Make a stab incision at this point and
dissect down to the bone. Place the tip
of the drill bit against the bone. Verify
that the tip of the drill bit is in the center
of the hole. While keeping the tip of the
drill bit against the bone, move the other
end of the drill bit into other positions
and take additional fluoroscopic images
to verify the position of the tip in the
center of the hole. Align the drill bit with
the C-arm beam. Tap the drill bit into the
bone using the MALLET.
Loosen the SET SCREW and remove the
DISTAL TARGETING WAND, leaving the
DRILL BIT in place. Slide the FREEHAND
TISSUE PROTECTION SLEEVE over the
DRILL BIT (Fig. 25).

Fig. 27
Fig. 26
Attach the DRILL to the DRILL BIT and
advance the drill bit through the bone.
Verify that the drill bit has gone through
the hole in the nail.
Remove the drill bit. Measure the depth
of the hole using the FREEHAND SCREW
DEPTH GAUGE (Fig. 26).
Alternatively, the appropriate length
of screw can be measured using the
numbered etch on the DRILL BIT closest
to the end of the FREEHAND TISSUE
PROTECTION SLEEVE when the DRILL
BIT is in the bone and the SLEEVE is
touching the bone (Fig. 27). Insert the
appropriate length screw using the
screwdriver.
If using the CAPTURED SCREWDRIVER,
place the appropriate screw on the
3.5mm HEX and tighten the screw to the
CAPTURED SCREWDRIVER by turning the
knob next to the handle clockwise.
CAUTION: If using the CAPTURED
SCREWDRIVER, do not torque the
CAPTURED SCREWDRIVER beyond the
calibration line next to the handle.
CAUTION: Do not drive the screws into
the bone under power, as damage to the
bone, screws and nail could result.
NOTE: Do not overtighten the screws.
Repeat these steps to insert additional
distal screws.

Finalize Implant Placement
Observe the depth of the nail in proximal
tibia. Ridges in the targeting guide barrel
indicate depths of 5, 10 and 15mm.
Disconnect the TARGETING MODULE
from the TARGETING GUIDE HANDLE and
set aside. Place a 2.0MM PIN through
the guide against the proximal screws.
Loosen and remove the CONNECTING
BOLT from the nail (Fig. 28). Remove the
TARGETING GUIDE HANDLE and set aside.
Assemble the ENTRY CANNULA with the
blue ENTRY CANNULA HANDLE and slide
over 2.0MM PIN.
Choose the appropriate height TIBIAL
NAIL CAP. Secure the selected NAIL CAP
to the NAIL CAP INSERTER using the NAIL
CAP RETAINING SHAFT (Fig. 29). Slide the
TIBIAL NAIL CAP over the 2.0MM PIN and
tighten to the nail (Fig. 30). Using the
C-arm, verify that the cap is completely
seated to the top of the nail.
Disengage the NAIL CAP INSERTER from
the TIBIAL NAIL CAP. Remove the 2.0MM
GUIDE PIN.
Close all wounds and apply the
appropriate dressings.
Postoperative Care
Early range of motion exercises of the
knee and ankle are encouraged. Allow
toe-touch weight bearing to progress
to full weight bearing as fracture callus
increases on the x-ray films.
Nail Extraction
Because of the potential for damage
to intra-articular structures, use a
standard parapatellar incision for any
nail extractions. Do not extract the nail
via a suprapatellar approach. Before
attempting to remove any screws or nail
caps, clean any bone from the hex of the
screw or cap.
Use the C-arm to locate any distal screws.
Remove the screws using a 3.5mm hex
screwdriver. Remove the nail cap (if one
was inserted) with the CONNECTING BOLT
INSERTER or another Zimmer 5.0mm hex
screwdriver. Expose the proximal screws
and use a 3.5mm hex screwdriver to
remove them.
NOTE: Use the specific captured
screwdriver.
To remove the nail, slide a 2.0mm
Guide Pin through the nail. Insert the
CANNULATED EXTRACTION ADAPTER
over the wire into the top of the nail.
Tighten the adapter to the nail. Attach a
slaphammer or other impaction device
and impact to back out the nail.
