CDS®Elbow Brace Flexion
User Instructions
1. Introduction
1.1. Foreword
Dynamic spring-loaded orthoses can be used
to treat joint contractures caused by both
neurological and orthopaedic conditions.
The shortening of the tissue surrounding the
joint decreases the range of motion affecting
the patient’s everyday life. Therefore, our
CDS®-concept aims to increase the range of
motion without pain by applying a constant,
appropriate low load prolonged stretch (LLPS).
1.2. Customer information
For your own safety please read through these
User Instructions carefully and accurately
before using the brace. The instructions, notes
and procedures must be read and understood
thoroughly in order to benefit from the correct
operation and use of the device. If anything
in the User Instructions is not clear, or any
instructions, operating procedures or safety
information is not fully understandable, please
contact the appropriate specialist retailer or
albrechtGmbH directly, before you use the
brace. This particularly applies to the safety
instructions.
1.3. Mode of operation
The CDS®Elbow Brace Flexion functions
according to the CDS®-principle and has
been designed to treat a flexion deficit of the
elbow. The brace applies a dynamic low load
prolonged stretch to simulate growth in the
contracted tissue. The adjustable redression
range protects the tissue from painful
overstretching.
1.4. Application
The brace has been designed exclusively for
the orthotic treatment of the elbow joint and
for contact with intact skin.
1.5. Scope of delivery
The CDS®Elbow Brace Flexion is delivered to
you ready to use in the size requested, with
User Instructions and labeling on the product
Please check the completeness of the brace at

CDS®Elbow Brace Flexion
User Instructions
1.10. Safety Instructions
The optimal effect of the brace is only
achieved when used correctly.
• The brace must only be used in the intact,
complete and mechanically undamaged
condition and with complete and intact
cushioning and walers. This must be verified
by the user before each usage.
• Opening or removing one or more belts,
as well as excessive loosening of the waler
when using the brace leads to a reduction of
the therapeutic effect of the brace and may
lead to injury.
• The brace must not be worn over open
wounds.
• The skin should be free of oils, grease, gels
or other debris, to prevent reactions with the
skin or the structure of the material.
• The orthosis should fit firmly but not
too tight, so as not to restrict the blood
circulation and adversely affect nerve and
lymph vessels. Excessive compression is
therefore to be avoided.
• Combination with other products is currently
not provided for or is to be agreed with the
manufacturer in writing.
• The brace is not intended for single use,
but is intended for multiple use by a single
person.
• The product as delivered is not sterile.
• Contact your physician immediately in the
event of an allergic reaction.
• Please note that cushioned sections can heat
up under direct sunlight. Protect the orthosis
from direct sunlight if necessary.
• Currently there is no test for flammability.
Exercise caution when using the orthosis
in the direct vicinity of open flames such as
lighters and cigarettes.
• The mechanical functions must only be
adjusted using the supplied tools in order to
avoid injuries and damage of the hinge.
• When adjusting the hinge rods to the shape
of the extermity by using an orthopaedic
bending iron, you must not bend the rods in
the area of the hinge housing or the hinge
cover as this could lead to damage or break
of the hinge.

User Instructions
1.11. Warranty
In addition to the legal warranty, we provide
a 6-month durability guarantee for the
orthosis. If properly used, this guarantees
that the orthosis will function without fault.
This excludes the padding and straps, which
are usually liable to a certain amount of
wear and tear. This kind of wear and tear
does not represent a product defect. This
manufacturer’s warranty is subject to the
condition that the orthosis is used as a medical
rehabilitation device and for no other purpose
than that described in the instructions for
use. Changes to the orthosis or the removal /
damage to the quality management seal will
invalidate the warranty.

2. Adjustment by the orthopaedic technician
2.1. Fitting to the patient
• Our CDS®braces are constructed to be adjustable.
• The position of the shell components can be changed and they can be shaped.
• The hinge rods can be adapted to the shape of the extremity by using an
orthopaedic bending iron.
• The strap lengths can be adjusted to different girths and shortened if
necessary.
2.1.1. Adjusting the brace to the arm shape by using an
orthopaedic "bending iron"
The brace is anatomically contoured. However, if a different shape is required,
the hinge rods can be adjusted to the shape of the patient’s arm with the aid of
an orthopaedic bending iron.
Loosen the screws on the shell components and either move or remove them.
Then adjust the hinge rods to the shape of the extremity.

upper arm rod. The position of the redression and limtation range can be thereby altered and
adjusted to the patient. The position of the stops depends on the position of the redression and
limitation range.

2.2.3. Setting the limitation for
CDS®Elbow Braces Flexion L/L, M/M, S/S and Junior
The limitation restricts the range of motion.
Flexion and the redression range are limited by the stop screw. In a second step,
the set value can be reduced up to a maximum of 15°, enabling infinitly variable
adjustment of the redression range.
1.Before setting the limitation, you must deactivate the spring tension. Turn the
switch to “off”.
2.Bring the brace into extension.
3.There are three holes on the side of the CDS®housing. The number of
degrees depends on the position of the redression and limitation range and
can be determined with a goniometer. The stop screw is located in one of
the holes. Then turn the stop screw with the supplied tool from the CDS®
housing.
Before screwing it into one of the three holes, bring the brace into extension,
so that the holes are freely accessible. Positon the stop screw in the desired
position and tighten the screw.

the activation mechanism of the hinge is set to this the position and the
patient can reactivate the spring tension in this position.
3.To facilitate attaching of the brace on the patients, adjust the length of all
brace straps to their maximum length without unthreading them. First open
the wide elastic upper arm strap. Now open the remaining straps by opening
the clips.
For XS/XS and Bambini, you must open and close the straps in order to attach
and remove the brace.
