Concept 4D orthosis | Aids for children with plexus paresis
In cooperation with Dr. med. Jörg Bahm (Head of Plexus Surgery at the University Hospital RWTH Aachen), we were able to develop a dynamic corrective positioning orthosis for children with a condition following birth trauma plexus paresis.
What is Obstetric brachial plexus palsy (OBPP)?
Nerves connect the brain with the body or muscles and send important information back and forth. If the nerves have been injured, for example during childbirth, this subsequently affects the child's muscles. The messages sent by the brain no longer reach the muscles in full.
Basically, the arm is supplied by the nerve plexus "plexus brachialis". The nerves run from the cervical spine through the shoulder to the upper and lower arm and are responsible for allowing the arm to move and feel. After an obstetric brachial plexus palsy (also Erb's or Klumpke's palsy, brachial plexus injury), these nerves are injured, which in turn affects the musculature and sense of touch.
How does the Concept 4D orthosis according to Pohlig/Bahm work?
The Concept 4D orthosis consists of individual modules that are used depending on the required mode of action. Due to its special design, the Concept 4D orthosis can act in four dimensions simultaneously:
1. Shoulder: It supports the shoulder in external rotation with the upper arm in the best possible position (adduction).
2. Elbow: The elbow joint remains freely movable
3. Forearm: It corrects the supination or pronation malposition in the forearm statically or dynamically
4. Hand & thumb: If necessary, it statically positions a drop hand and a collapsed thumb.
Advantages of the Concept 4D orthosis
The great advantage of the Concept 4D orthosis is that it can be optimally adapted to the child's individual situation. The settings for the shoulder and elbow joints can be varied dynamically. If necessary, movement limitations can be set. Thanks to the individual modules, the Concept 4D orthosis can be donned and doffed separately, allowing even more targeted adjustment of the corrective effect.
Thanks to the 3D printing process, we can use an extremely lightweight, air-permeable, flexible and at the same time robust material for the orthosis. The Concept 4D orthosis has an appealing design and color for children and is very user-friendly.

Eine gute Erfindung ❤ danke

[@yousafyousaf-ib9qn]

what program are they using to model the orthosis ??? if any idea let me know

[@pohliggmbh]

I think the software is called: Geomagic Freeform
