Bionic prosthesis: easy to put on, intuitive to use

22/09/2020

Patients who receive a prosthesis after the amputation of a limb often have to train for weeks or months until they can control the technology and use it in everyday life without problems. At the Medical University of Vienna, the world's first bionic prosthesis has now been developed that has a closed control loop and enables immediate, intuitive use.

Versatile new material family could build realistic prosthetics

17/08/2020

Nature's blueprint for the human limb is a carefully layered structure with stiff bone wrapped in layers of different soft tissue, like muscle and skin, all bound to each other perfectly. Achieving this kind of sophistication using synthetic materials to build biologically inspired robotic parts or multicomponent, complex machines has been an engineering challenge.

Replacing hip prostheses – removing bone cement with the laser

14/08/2020

When hip prostheses are replaced, the old bone cement in the femur must first be removed – a complicated procedure. The Laser Zentrum Hannover e.V. (LZH) is developing an endoscope-based laser system with which doctors should be able to remove the old cement more gently and with an improved vision.

Repurposed spinal stimulators to restore touch in lost limb

21/07/2020

Imagine tying your shoes or taking a sip of coffee or cracking an egg but without any feeling in your hand. That's life for users of even the most advanced prosthetic arms. Although it's possible to simulate touch by stimulating the remaining nerves in the stump after an amputation, such a surgery is highly complex and individualized.

MoreGrasp – being able to grasp again with paraplegia

22/11/2018

Every year between 250.000 and 500.000 people suffer a spinal cord injury, MoreGrasp is intended to make their lives easier. The project aims to restore the lost gripping function in people with high paraplegia. Researchers at Graz University of Technology have developed a neuroprosthesis that is currently undergoing a feasibility study.

Regenerative heart valves: from simulation to replacement

23/07/2018

Every year, more than 250,000 patients worldwide receive heart valve implants. Children require repeated replacement surgery because their bodies are still growing, the prosthetic heart valves are not. Regenerative heart valves solve this problem. Until now, we have only been able to monitor how these living implants develop in the body after the fact. Computer models now make this predictable.

Light and Bluetooth – dynamic measurement techniques for orthopedics

02/05/2018

X-rays for diagnostic imaging and therapy evaluation are still the norm in orthopedics. Meanwhile, patients who frequently need X-rays are repeatedly exposed to radiation. That's why the University Hospital RWTH Aachen uses and develops methods that are not just radiation-free but can also capture motions.

Biomechanical measuring systems: Versatile tools for many disciplines

02/05/2018

When human movements are no longer as smooth as they should be – due to misalignments or as the result of an injury for example – biomechanical measuring systems spring into action. Thanks to different types of sensors and optical technologies, physicians, therapists, and sports scientists embark on a search for possible causes and corrective options.

Surgical navigation systems – with precision to the destination

06/03/2018

With the help of surgical navigation systems, prostheses or implants can be better inserted. During the procedure, surgeons can see exactly where they need to operate on a screen. Just like a navigation system in the car, navigation in the OR guides you precisely to your destination. At the Uniklinik RWTH Aachen we can find out what advantages this has for physicians and patients.
