When illness,
injury or disability strikes, the loss of
normal function can be a devastating blow to
you and your family. You may be unable to
move around safely and easily, unable to
work or care for yourself or your family, unable to enjoy life to its fullest. When
this impairment involves your arms, legs or
spine it may be necessary to provide support
with an orthotic device, sometimes called a
brace. Orthoses come in many styles and
materials.
They can be either pre-fabricated or custom
made, simple or complex, lightweight or
heavy-duty. There are many options and
features to consider, and it takes a highly
trained individual to properly assess the
situation and formulate a plan for the best
result. This clinician called an orthotist,
and the best orthotists have a high level of
education and training. At Sai, Inc. we
employ only ABC certified or board-eligible
practitioners.
TAMARACK
FLEXURE ANKLE JOINT
Tamarack Joint self co-align the medical and
lateral Joint axes. The unique high strength
inner filament core prevents elongation and
ensure precise hinging action. For the
patients with:
• Foot drop
• Flaccidity at Ankle during support
Available at 3 different sizes
 TAMARACK
DORSIFLEXION-ASSIST FLEXURE ANKLE JOINT
The biased design provides motion assist
power similar to traditional metal dorsi-assist
ankle joints.
For the patients with:
• Mild/ Moderate Spasticity or Drop foot
• Dorsiflexors Weakness
Available in six different sizes with three
durometeres i.e.75, 85 & 95 to provide the
amount of motion assistance required for the
patients.
 TAMARACK
VARIABLE ASSIST ANKLE JOINT
The Tamarack variable assist allow the
practioner to adjust moments of the joints
to any value from zero to nearly three times
what is possible with standard installation.
• When greater adjustability or angular
range of motion is required
• High plantar Flexure tones (mild
contracture) needs gradual corrective
adjustment.
• To avoid frequent change of AFO after
corrections
 TAMARACK
CLEVISPHERE ANKLE JOINT
Clevisphere ankle joint is a free motion
adjustable stop ankle joint that features a
spherical wing which can rotate about any
axis within a 24 conical range and provides
automatic co-alignment of the medical and
lateral joint axes. For the patients with:
• Flexible Varus/Valgus position during gait
or drop foot.
• Flaccidity at Ankle during support and
tibial torsions.
Comes in adult size only.
 CAMBER
AXIS HINGE ANKLE JOINT
• Camber Axis Hinge Ankle Joint provides
variable range of motion or fixed ankle
positioning for patients.
• A durable stainless steel joint that
eliminates the need for posterior stops.
• Colour code keys allow variable degrees of
control from fixed ankle to limited motion
of planter or dorsi flexion.
Available in three sizes.
Can be used at other joint locations.
SCOTTY FREE MOTION ANKLE JOINT
Scotty is a free motion stainless steel
ankle joint.
For the patients with:
• Mild mediolateral instability
• Flexible Varus/Valgus position and foot
drop
Available in two size:
780 L – Large with a length of 76mm
780 S – Small with a length of 64mm
 OKLAHOMA
ANKLE JOINT
Oklahoma is a cost effective method for
creating a free motion AFO. When utilized
with posterior stop range –of –motion
control is added to the AFO.
For the patients with:
• Mild Mediolateral Ankle instability
• Mild Ankle spasticity or Drop Foot
Available in 5 sizes with Polypropylene or
Nylon (High Density)
WHAT MAKES
THE UNLOADER ONE® SO UNIQUE?
In 1986
inventors started developing a new concept
for OA bracing.
The 3-Point
Leverage System is born. The theory was
that, by adding a valgus bend to a single,
medial upright, the upper and lower shells
of the brace frame would act as leverage
arms when the counter force of a diagonal
Dynamic Force Strap® was applied. This would
unload weight from the medial compartment of
the knee, relieving pain. The first study.
After consultation with the medical
community, a groundbreaking scientific study
examining the efficacy of
lateral and medial hinge placement for
treating medial OA was conducted. This study
ultimately concluded that medial valgus
bracing resulted in significant reduction of
pain. With a scientifically proven method
and patents in place, these new custom knee
braces were launched. Quickly, this viable
option for treating unicompartmental
osteoarthritis of the knee gathered
momentum. Eventually, lateral hinge
placement was used to treat lateral
compartment symptoms.By the mid-‘90s, the
new Unloader brace was being used around the
globe and the name Unloader became
synonymous with OA knee bracing.
The latest
technology: Unloader One. Unloader One
is the most signficant re-design of the
Unloader concept since its inception.
Available in both custom and OTS models,
Unloader One offers a unique twist on the
traditional 3-Point Leverage System. The
brace has a flexible upright and Dual
Dynamic Force Straps disperse the counter
force across two points of contact. With a
racheting Dynamic Force Control System and
padding that features Ossur Sensil® Silicone
Technology Unloader One offers superior
unloading power and minimum risk of
migration. The Unloader One has been
streamlined to half of its former weight
while increasing the unloading power and
improving comfort and compliance.
THE 3- POINT
LEVERAGE SYSTEM
the fundamental
component of unloader osteoarthritis knee
braces is the 3-point leverage system, which
consists of a single upright plus diagonal
dynamic force strapstm.
