The objective of external fixation is to bring stability to a long bone
that has sustained a fracture. This process must be as physiological
as possible and therefore, the fixation device used must be stable
enough to prevent reduction loss and resist movement in lateral
bending and torque, yet be dynamic enough to allow minute and
controlled amounts of movement at the fracture site during weight
bearing. DDyynnaammiissaattiioonn iiss tthhee tteerrmm ggiivveenn ttoo tthhee ttrraannssmmiissssiioonn ooff

“Healing of the bone fractures using external fixation takes place by
indirect consolidation, and fractures treated by micromovement heal
more quickly than those treated using a rigid external fixator (13
weeks as compared to 18)”.1
The precise amount of weight bearing is dependant on the
type of fracture, soft tissue damage, total weight of the patient,
presence of multiple trauma, pain threshold and the patient's overall
condition.
Dynamisation should occur at the first sign of periosteal
callus formation and the fixator should be set for 1mm of
micromovement at the fracture site (see protocol on page 6).
The Monotube® Triax™ is designed to provide a high degree of
stability, yet permit dynamic movement due to its built in dynamisation
module. The Monotube Triax can easily be converted from static to
dynamic mode by activating the dynamisation module.
The biology of the fracture can be modified by adjusting the external
fixator. Rigid external fixators produce primary bone healing, whereas
elastic fixators produce a greater volume of periosteal callus.2

The second type of dynamisation is referred to as AADDJJUUSSTTAABBLLEE
BBIIOO--SSPPRRIINNGG, and is the combination of an axial telescopic function
and a compressive spring. The objective of this shock absorbing
mechanism is to counteract muscle tension and prevent the collapse
of the fragments in an unstable fracture or a leg lengthening
procedure, yet at the same time to guarantee accurate and effective
dynamisation.
The Adjustable Bio-Spring allows the surgeon to “dial in” the amount
of compression at the fracture site by simply opening the
dynamisation collar from 0 – 1mm, and set the compressive spring to
full tension, based on the fracture type and the patients weight.
Adjustable Bio-Spring is recommended in unstable fractures or
fractures in which there is no cortical contact and leg lengthening
procedures.

Stable Fracture patternsBiocompression is recommended for stable fracture patterns. The
frame may be dynamised anytime after application. The following
steps should be followed:
1. Open the dynamisation collar to 1mm (one complete revolution of
the dynamisation collar equates to 1mm). Use the dynamisation
wrench if necessary.
Note: The one millimetre setting on the collar may or may not be
visible.
Unstable Fracture patternsAdjustable Bio-Spring is recommended for unstable fracture patterns
and leg lengthening. The frame may be dynamised once callus is
evident on the X-ray, approximately 21 to 28 days postoperatively. To
dynamise the frame, the following sequence should be followed:
1. Advance Adjustable Bio-Spring tension screw clockwise until fully
compressed, about 71/2 full turns. The screw will recede into the
tube as it compresses the spring.
2. Open the dynamisation collar to one millimetre. Use the
dynamisation wrench if necessary.
3. Reduce Bio-Spring tension one full turn anti-clockwise each week.
Be sure to check that biocompression collar is still set at 1mm
after each spring adjustment. The force required to dynamise the
frame will be progressively reduced (see technique guide).
Note: X-ray visualisation is required to determine callus formation.

The Monotube® Triax™ has a built in compression distraction
mechanism, which can be used in lengthening procedures and to
adjust fracture gaps.
Compression and Distraction are achieved by turning the Lengthening
Screw – turning the 7mm squared headed screw anti-clockwise will
lengthen the tube and distract the fracture. Turning clockwise will
shorten the tube and compress the fracture.
The end of the tube is marked with a visual reference each 1/4 turn

The Monotube Triax system is available in three sizes which are
colour coded Yellow, Blue, Red.
To determine the proper frame components the size of tube selected
is determined by:

The Monotube® Triax™ Pin Clamp allows independent control of
the fracture reduction in three planes. Clamps may be placed
anywhere along the length of the tube at virtually any angle, wherever
the best bone purchase may be available.
A unique compression sleeve allows for excellent mobility in rotation
preventing deviation of the pin clamp while guaranteeing maximum
stability.
The two outer square head screws A when tightened hold the pins in
the clamp. Each screw can independently lock up to two pins in place.
The red and blue Triax Clamps have four pin positions, and the yellow
Triax Clamp has two pin positions.
The centre square head screw B allows for +/- 20° degrees of
angulation in the sagittal plane.
The side square head screw C allows for 360° of rotation in the
coronal plane.
The square head screw D at the bottom of the clamp allows for
translation along the length of the tube and for 360° rotation around
the axis of the tube.
Note: All square head screws need to be tightened to the appropriate
torque to maintain adequate stability using the torque wrench (picture
of use).

T-clamps are beneficial when treating proximal and distal fractures or
fractures that span a joint. The T-clamp allows for perpendicular
placement of pins.
Standard Monotube® Triax™ Clamps can be converted to T-clamps
utilising the T-adapter. Be sure you select the appropriate adapter for
the size of clamp to be modified.
Assembly Instructions1. Select the appropriate T-adapter.
2. Remove body screw and compression sleeve from T-adapter.
3. Remove body screw and compression sleeve from Standard Pin
Clamp. Separate pin connector from tube coupling.
4. Insert T-adapter into tube coupling and replace compression
sleeve. Body screws C should be introduced through the recessed
portion of clamp until fully seated and finger tight.
5. Insert pin connector onto T-adapter and replace compression
sleeves. Body screw C should be introduced through recessed
portion of the clamp until fully seated and finger tight.
NOTE: Body screws and
compression sleeves are exactly
alike and will fit in either position.
However, if body screws are not
started from recessed side of the
clamp, they will not fully seat. In
addition, the T-adapter should
always be connected to the tube
coupling before the pin connector.

The Monotube® Triax™ Single Pin Clamps are designed for
independent pin placement. They allow for capture and stabilisation of
fracture fragments. They are also intended for use in pathologies that
require non parallel pin position for additional stability of the frame.
The Single Pin Clamp features a snap-fit fixation mechanism which
ensures an easy and firm grip to the fixation pins. A serrated
interlocking mechanism between the jaws of the Pin Clamp provides
superior rotational locking. A 7mm square head screw allows easy
access. Pins can be placed parallel or convergent to improve stability.
The Monotube Triax Single Pin Clamps come in three sizes and
accept the following Apex® pins
Yellow 3/4mm dia. Blue 4/5mm dia. Red 5/6mm dia.
Top locking for adjustable control of the pin placement.
The Single Pin Clamp allows 360° of rotation in the coronal plane.
The square head screw positioned at the
bottom of the pin clamp allows for
translation along the length of the tube
and 360° around the axis of the tube.
The Monotube Triax tube-to-tube Clamps allow connection of Red,
Blue, and Yellow tubes in various combinations to treat complex trauma
or pelvic fractures.

Triax Tube-to-Tube
The Monotube® Triax™ can be connected to the TenXor™ carbon ring
by using a ring-to-tube clamp. Such a Triax Hybrid Frame was
designed to address C type fracture of the proximal and distal tibia
using K-wires. It combines the principles of the circular ring and
unilateral frame fixation to better neutralise the forces acting upon the
fracture.
The TenXor carbon ring is available in various sizes and the ring-to-
tube clamp is available in 2 sizes for blue and red Monotube Triax.
Its main features are:
Possibility of sliding along the ring in order to determine the best
position according to frame configuration
Integrated snap-fit mechanism for "clicking" the clamp on the
ring

If no dynamisation is required or a radiotranslucent frame is needed,
Triax™ Carbon Tubes can be used in place of the Dynamic Tube.
Triax Carbon Tubes are available in 3 diameters; Yellow 15,
Blue 20, Red 25 and in lengths from 150 – 400mm
The use of Triax Carbon Tubes does not alter the surgical
protocol, except that the colour coded end caps must be
removed before placement of the Monotube® Triax™ Clamps.
Unlike the Dynamic Monotube Triax the Triax Carbon Tubes
require an external compression/distraction device.
To use the device, position the chariot over the back of the
standard Triax pin clamp, and wrap the swivel clamp around the
tube. Tighten the 7mm square head screw A, then proceed to
loosen pin clamp square head screw D.
Compression or distraction can now be achieved. Maximum
distraction/compression is:-
Yellow 20mm
Blue 30mm
Red 30mm
1 revolution of square head screw B provides 1mm of
compression or distraction. After distraction or compression is
completed, re-tighten pin clamp square head screw D. The
external compression distraction device may now be moved.

The Monotube® Triax™ external fixation system was developed in
cooperation with Prof. J. Lazo-Zbikowski and Prof. J. Cañadell.
Its design consists of a dynamic axial fixator designed to maintain
rotational and angular stability while allowing the bone to share the
load in the axial plane.
The Monotube Triax has been designed to handle a wide variety of
orthopaedic and trauma applications keeping in mind the need for
ccoonnttrroolllleedd ddyynnaammiissaattiioonn. The built in dynamisation collar allows 0-
1mm axial compression thus allowing the surgeon to initiate the
nnaattuurraall ccaalllluuss ffoorrmmaattiioonn that is critical to the healing process.
Its absolute modularity and uunnrreessttrriicctteedd rreeppoossiittiioonn ppoossssiibbiilliittiieess
allow restoration of the correct anatomy in three planes.
The system consists of tthhrreeee bbaassiicc ccoommppoonneennttss. The dynamic tube,
the pin clamp, and the single pin clamp. Speciality clamps and
accessories are also available.
Overview
The Monotube® Triax™ system can be ddyynnaammiiccaallllyy llooaaddeedd
upon muscular contraction and weightbearing. This allows the
system to be converted from a static to a ddyynnaammiicc mmooddee by
activating the built in dynamisation collar. This will stimulate
and enhance callus formation and promote faster healing.1
The Monotube Triax is mmiinniimmaallllyy iinnvvaassiivvee using only
percutaneous Apex® Pins which are nnoonn ccoonniiccaall and therefore
avoid radial stresses at the bone to pin interface
and reduce soft tissue disruption.
The Monotube Triax simple design characteristics make
its use eexxttrreemmeellyy vveerrssaattiillee and easy to apply thanks to
uunniivveerrssaall iinnssttrruummeennttaattiioonn and few basic components.
The Monotube Triax is ssiimmppllee ttoo uussee,, by sliding the desired
clamps anywhere along the tube. Fine tuning the reduction is
simple, and requires no additional components.
The Monotube Triax system is available in tthhrreeee ssiizzeess allowing
the surgeon to choose the appropriate fixator according to
patient size and indication requirements.
All the adjustments on the tube and clamp use 7mm square
head screws in the red and blue and 5mm square head screws
in the yellow and require only one instrument.
The Monotube Triax is ffuunnccttiioonnaall,, allowing patients partial
weightbearing from the beginning of the treatment.
The Monotube® Triax™ system is designed to permit two types of
dynamisation, BBiiooccoommpprreessssiioonn aanndd AAddjjuussttaabbllee BBiioo--SSpprriinngg. The first
is an axial telescopic function in which an outer tube slides over an
inner tube, allowing a recommended 1mm micromovement at the
fracture site.
Biocompression allows the surgeon to “dial in” the amount of
compression at the fracture site by simply opening the dynamisation
collar from 0 – 1mm from the beginning. This micromotion is
controlled by a specially designed needle-bearing technology that
allows the tube to slide effortlessly even if not axially aligned. Other
systems have a tendency to jam in this situation. This specialised
technology guarantees appropriate dynamisation and therefore,
callus formation leading to faster healing.
Biocompression is recommended for stable fractures or in fractures
where there is substantial cortical contact.
