Implants: 3D-printed skull provides window to brain

04/04/2019

Researchers at the University of Minnesota have developed a unique 3D-printed transparent skull implant for mice that provides an opportunity to watch activity of the entire brain surface in real time. The device allows fundamental brain research that could provide new insight for human brain conditions such as concussions, Alzheimer's and Parkinson's disease.

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.

Implants: From foam to bone

20/03/2019

Researchers from the University of British Columbia and McMaster University have developed what could be the bone implant material of the future: an airy, foamlike substance that can be injected into the body and provide scaffolding for the growth of new bone.

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.

Implants: New method for developing artificial ovaries

04/03/2019

An interdisciplinary team of researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) led by Prof. Aldo R. Boccaccini from the Chair of Materials Science (biomaterials) and Prof. Dr. Ralf Dittrich from the Department of Obstetrics and Gynaecology at Universitätsklinikum Erlangen have taken an important step towards developing artificial ovaries for patients suffering from cancer.

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.

Powering a pacemaker with a patient's heartbeat

22/02/2019

Implantable pacemakers have without doubt altered modern medicine, saving countless lives by regulating heart rhythm. But they have one serious shortcoming: Their batteries last only five to 12 years, at which point they have to be replaced surgically.

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.

Gummy-like robots prevent disease

08/02/2019

Human tissues experience a variety of mechanical stimuli that can affect their ability to carry out their physiological functions, such as protecting organs from injury. The controlled application of such stimuli to living tissues in vivo and in vitro has now proven instrumental to studying the conditions that lead to disease.

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.

Ophthalmology today and tomorrow: surgery and more

01/02/2017

Ophthalmology procedures and eye surgeries have been around since ancient times. Today we can hardly imagine the types of circumstances that surrounded any surgical procedures to our perhaps most important sense organ in those days and later eras. Meanwhile, the present and future of this medical specialty looks all the more promising.
