Endoprotheses: between possibility and reality

01.01.2020

When natural joints lose their ability to function, they can be completely or partially replaced by artificial joints, also called endoprotheses. Endoprotheses must be of a certain quality, as they should remain in the body as long as possible. In addition to some risks, endoprotheses can also contribute to a mobile and carefree life for young and old.

APRICOT-project: implant "help(s) patients heal themselves"

01.01.2020

Today, people tend to live longer, while an increasing number of patients suffer from osteoarthritis. Even younger generations are now at a higher risk of getting osteoarthritis due to the frequent use of mobile devices. The EU research project APRICOT aims to develop a novel type of implant for the treatment of osteoarthritis of the hands – helping patients heal themselves.

Endoprotheses: regaining independence and mobility

01.01.2020

Joints can suddenly or gradually deteriorate and lose their natural strength, whether it’s due to accidents, diseases or simple wear and tear. In some of these cases, implants of artificial joints – endoprostheses - can help. As a joint replacement, they are designed to stay in the body for as long as needed and as such improve the patient’s quality of life and mobility.

Tissue Engineering: tracking lab-grown tissue with light

16.12.2019

New proof-of-concept photonic pH sensor could advance studies of tissue regeneration. Someday, doctors would like to grow limbs and other body tissue for soldiers who have lost arms in battle, children who need a new heart or liver, and many other people with critical needs.

'Smart' surfaces help to improve blood-vessel grafts

03.12.2019

Researchers at McMaster University have created a new coating to prevent clotting and infection in synthetic vascular grafts, while also accelerating the body's own process for integrating the grafted vessels.

Implants: novel sensor improves significance of NMR brain scans

27.11.2019

A team of neuroscientists and electrical engineers developed a highly sensitive implant that enables to probe brain physiology with unparalleled spatial and temporal resolution. Now published in Nature Methods, they introduce an ultra-fine needle with an integrated chip that is capable of detecting and transmitting NMR data from nanoliter volumes of brain oxygen metabolism.

Bone: dissolving screws

07.11.2019

Where bones fracture, surgeons often have to join the fragments with implants. Magnesium orthopaedic screws, which over time dissolve in the body, spare patients another operation after healing is completed and reduce the risk of infection. To develop optimized alloys and orthopaedic screws with functionalized surfaces, Empa researchers are now investigating magnesium corrosion.

Implant: 3D printing, bioinks create blood vessels

24.10.2019

A biomimetic blood vessel was fabricated using a modified 3D cell printing technique and bioinks, which were formulated from smooth muscle cells from a human aorta and endothelial cells from an umbilical vein.

Cataract surgery: more safety on the road

18.10.2019

The ability of cataract surgery to restore sight is well known. People say they're stunned by the vibrancy of color after surgery and the improvement in night vision. Some can even reduce their reliance on glasses. But is it possible to quantify that improved quality of vision?

Orthopedic implant: More comfortable thanks to full weight-bearing capacity

08.03.2019

Orthopedic implants – they are a necessity when it comes to congenital or acquired limb length discrepancies. However, full weight-bearing during the limb lengthening process is not feasible with previous implant models. For the first time, the 3D Surgery division at the Medical Center of the University of Munich has succeeded in using an implant that facilitates immediate weight-bearing.

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.

Early detection: Tattoo signals cancer – and more

09.07.2018

People who are not ill and do not show any symptoms typically do not visit the doctor. And while most people know that preventive medical checkups for cancer, for example, are important, they still avoid them. They tend to be very hesitant because the doctor might detect a serious illness. In the future, a new type of implant could make it easier to go to a screening test.

Tissue engineering: how to grow a bypass

23.04.2018

A bypass is a complicated structure. It is either made of synthetic materials that can cause blood clots and infections or created by using the patient’s veins. However, the latter often does not yield adequate material. A newly developed bioreactor could solve this problem in the future. It is designed to tissue engineer vascular grafts by using the body’s own material.

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.

High-quality implants and orthopaedic instruments - Interview with GPC Medical Ltd.

16.11.2017

The quality of the implants and orthopaedic instruments used is a fundamental prerequisite for the success of surgical procedures. They have to meet very high international standards. Find out more about the orthopaedic implants and tools of the Indian company GPC Medical Ltd. in our interview.

Cochlear implants: safe procedure thanks to surgical robots

22.05.2017

For many years, cochlear implants have restored a sense of hearing in people with certain types of hearing loss. For surgeons, the implantation requires a precise attention to detail under the microscope. The results for the patients improve significantly with a more precise placement of the electrode array. The use of a surgical robot can increase the accuracy of the procedure.

Hip joint: sleeve versus endoprosthesis

10.04.2017

People with hip osteoarthritis often suffer from severe pain and only an endoprosthesis implantation can provide relief. This involves a major intervention and long-term rehabilitation because the implant requires the removal of a section of the thigh bone. The "MioHIP" research project looks for an elastic alternative.
