Orthopedics: personalized prosthetics from the 3D printer

08/04/2019

With the growth of 3D printing, it's entirely possible to 3D print your own prosthetic from models found in open-source databases. But those models lack personalized electronic user interfaces like those found in costly, state-of-the-art prosthetics.

Microgels fight off bacteria of implants

27/03/2019

Joint replacements are among the most common elective surgeries - but around one in 100 patients suffer post-surgical infections, turning a routine procedure into an expensive and dangerous ordeal. Now, researchers at Stevens Institute of Technology have developed a "self-defensive surface" for these implants that release micro-doses of antibiotics when bacteria approach, reducing infection rates.

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.

Endoprostheses - Ultrasound to detect loosening?

27/02/2019

Many patients suffering from arthrosis or other kinds of damage in the hip joint need an endoprosthesis at some point. However, this prosthesis can loosen again after some time, so that it must be replaced. In order to delay this replacement surgery for as long as possible, the TH Mittelhessen University of Applied Sciences develops a new diagnostic method.

A prosthetic that restores the sense

22/02/2019

Researchers have developed a next-generation bionic hand that allows amputees to regain their proprioception. The results of the study, which have been published in Science Robotics, are the culmination of ten years of robotics research.

Hip implants: coating prevents aseptic inflammation, loosening

21/02/2019

A consortium of eleven research and industrial partners led by the Fraunhofer Institute for Production Technology IPT has now joined forces to develop a new generation of endoprosthesis for the treatment of aseptic loosening disease.

MRI and computer modeling reveals how wrist bones move

14/02/2019

We use our wrists constantly, but how do they work? In a just-published Journal of Biomechanics article, the researchers proved a longtime assumption about individuals' right and left wrists, while also finding differences between wrists of males and females: discoveries that could help inform and guide future treatments.

SoftHand: grasping intelligence for lower arm prostheses

10/12/2018

So far, lower arm prostheses often only functioned as a cosmetic disguise to conceal the missing body part. While newer models help the wearer with grip patterns, every hand grip has to be readjusted and newly activated. There is still no prosthetic device that is easy to control and allows a flexible response to objects the wearer is grasping.

Back pain: The research project Ran Rücken is intended to help

10/09/2018

About eight in ten Germans suffer from back pain during their lifetime. Too much or the wrong movements can also cause problems. "Ran Rücken", the interdisciplinary research project aims to determine the right minimum dose of exercise that proves effective. (Explanatory note: "Ran Rücken" can be loosely translated as "Target the Back")

Biomechanical measuring systems – motion and posture analysis in orthopedics

21/06/2018

Biomechanical measuring systems are used in orthopedics to diagnose and treat misalignments and diseases. The Velamed Company uses its high-tech solutions to measure biomechanical parameters that enable a holistic analysis of human movement and posture. We took a closer look at how this works.

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.

The surgeon's co-pilot: pin-point accuracy through electromagnetic navigation systems

04/01/2018

The position and alignment of surgical tools in the patient’s body must always be kept in view during the operation process to guarantee success and safety. With fine sensors at the tip of the instruments and an electromagnetic signal, Fiagon's electromagnetic navigation systems accurately reproduce their position in the body.

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.
