1.1. Foreword
The individual range of the albrecht GmbH
includes:
• CDS®Joint
• CDS®Nano joint
• CDS®Nano hybrid Joint
• CDS ®Micro joint
• ROM Nano adapter joint
• Various anchors for CDS®joints
• Various anchors for CDS®nano joints
• CDS ®Follower
• CDS®Nano Follower
• Coniungi connection unit
• Nano Hand piece
• CDS ®Straightening set
CDS®Joint /CDS® Nano joint /
CDS® Nano hybrid joint /CDS® Micro joint
Dynamic redression joints are used for
the treatment of both orthopaedic and
neurological joint contractures. The shortening
of the tissue surrounding the joint results in
movement restrictions, which significantly
affect the daily life of the patients concerned.
Therefore the aim of our CDS®treatment
plan is to eliminate movement deficits and
thus support a return to an "active life" by
means of suitably-dosed continuous treatment
without pain.
ROM Nano adapter joint
Functional joints are used to relieve and
stabilise the joint and ligamentous apparatus
after trauma and surgical procedures. Their
job is to protect joints and ligaments during
rehabilitation without stiffening them.
The joints provide protection and management
during the healing process and allow a
gradual, controlled return to full physiological
mobility.
1.2. Customer information
For your own safety, please read these
instructions slowly and carefully before using
the devices of the individual range. Only if
all instructions and procedures have been
thoroughly read and understood can proper
use and operation for the purpose intended
be possible. If something is not clear in the

Individual

instructions for use or if directions, operations
or safety information are not completely clear,
please contact the responsible specialist dealer
or go directly to albrecht GmbH before using
the device. This applies in particular to the
safety instructions.
1.3. Mode of operation
CDS®Joint /CDS® Nano joint /
CDS® Nano hybrid joint /CDS® Micro joint
The CDS®Joint /CDS® Nano joint /CDS®
Nano hybrid joint and/CDS® Micro joint are
based on the CDS®principle and are used to
treat joint movement deficits. Thanks to the
dynamic continuous pull, the joint stimulates
the growth of the shortened tissue.
ROM Nano adapter joint
The ROM Nano adapter joint stabilises and
relieves the joint during conservative and post-
operative rehabilitation.
The ROM Nano adapter joint can be
adjusted in 10° increments (from -10° to
100°). Thus, a physiological stretching is
possible.
1.4. Intended use
The products of the Individual range are
intended to be used exclusively for the orthotic
treatment of joints.
1.5. Scope of supply
After receiving the device, please check that it
is complete.

2. CDS®Joint / CDS®Nano joint
2.1. Selection of joints according to position of use and direction
of action
Remarks
—For treatment in the direction
of flexion: The CDS®Joints
and
CDS®Nano joints are basically
extension joints. For the
flexion a right joint is needed
instead of the left one (and
vice versa).
—For a hand or ankle joint
fitting, the joint is rotated
180° so that the anchor is
positioned distally.

2.3.1. Irons and holes of the pivot supports and anchors
The individual special joints and the various anchors are supplied with straight,
non-curved or recessed supports and can be individually processed and adapted
by you.
The following points must be observed when adjusting :
• When you bend the aluminium supports, be sure to heat the aluminium
slightly for the bending operation.
• Always use a round bending iron.
• Bend in several small steps (max. 20° steps).
• Do not bend in close proximity to the joint to avoid damage to the joint
(minimum distance: 5 mm)
• Very small bending radii must be avoided to prevent breakage of the support.
• Multiple corrections and changes to the bend direction must be avoided.
• A maximum bend angle of 90° must not be exceeded.
• When drilling the supports, you should follow the detailed instructions,
especially with VA material. You should always use a HSS/E drill bit to machine
the material and drill at a speed of 400-500 revolutions per minute to prevent
the material from hardening. Suitable HSS/E drills can also be purchased from
albrecht GmbH.

2.4.3. Set and adjust the spring tension to the strength required
by the patient
1 The set spring force is indicated by a scale from 0 to 15 and can be seen
through the viewing window on the CDS®housing,. The areas above 15 and
below 0 are marked in red.
To prevent damage to the CDS®Joint / CDS®Nano joint, do not rotate
into the red area of the joint viewing window .
2 Insert the tool into the hole on the side of the joint up to the stop. Turning
it clockwise or in the + direction increases spring tension, turning it
counterclockwise or in the - direction decreases spring tension.
2211
If two joints are used, the spring tension must be the same for both joints.
The spring tension can be adjusted to the course of treatment.
Activating or deactivating the spring tension does not change the strength of the
spring tension.
The spring force may only be adjusted in consultation with the attending
physician.

2.5. Redression range
The redression range of the CDS®Housing is 90°.
With the CDS®joint / CDS®Nano joint, the position of this redression area can
be freely selected by means of an adjustable joint support. This means that
the CDS®Joint / CDS®Nano joint can be used as both an extension joint and a
flexion joint. This also makes it possible to deal with extreme flexibility deficits,
for example.
