Hip and dental implant operations are routine. But not entirely risk-free. They may result in infection that is difficult to control with oral or intravenous antibiotics. In such cases, the implant will probably need to be replaced. Fraunhofer researchers can now apply a precisely matched drug directly to the replacement implant while significantly increasing the effectiveness of the antibiotic…
Researchers at McMaster University have solved a vexing problem by engineering surface coatings that can repel everything, such as bacteria, viruses and living cells, but can be modified to permit beneficial exceptions. The discovery holds significant promise for medical and other applications, making it possible for implants such as vascular grafts, replacement heart valves and artificial joints…
Breast surgeons across the UK must ensure women are aware of BIA-ALCL, a non-Hodgkin’s lymphoma that is associated with implants; and more responsibility must be taken to diagnose and report cases, surgeons attending the 2018 London Breast Meeting have warned. Hundreds of breast specialists from around the world met at the Royal College of Physicians for the four-day conference this autumn,…
A team of researchers at the University of Minnesota have, for the first time, fully 3D printed an array of light receptors on a hemispherical surface. This discovery marks a significant step toward creating a “bionic eye” that could someday help blind people see or sighted people see better. The research is published in Advanced Materials, a peer-reviewed scientific journal covering…
As the world’s largest cardiology congress gets underway in Munich, it’s worth looking back to previous ESC sessions to see how scientific debates have evolved. At ESC 2016, held in Rome, REM-HF investigators presented data suggesting remote monitoring in implantable cardiac devices offered no added clinical benefit. Two years on, there are new reasons to re-examine that conclusion, with a…
Could weight loss surgery before knee replacement improve outcomes or even eliminate the need for joint replacement in severely overweight patients? A study by researchers at Hospital for Special Surgery (HSS) aims to answer that question. Orthopedic surgeons often encourage obese patients considering knee replacement to try to lose weight before the procedure. The study, known as SWIFT (Surgical…
The FDA has been closely tracking the relationship between breast implants and a rare type of non-Hodgkin's lymphoma since we first identified this possible association. We’ve been working to gather additional information to better characterize and quantify the risk so that patients and providers can have more informed discussions about breast implants,” said Binita Ashar, M.D., director of…
Joint replacement surgery carries the risk of developing an infection in the replaced joint, which can lead to a so-called revision or re-do of the joint replacement. However, current diagnostic practices can fail to detect bacteria in 30-50 percent of clinical cases, complicating or delaying appropriate treatment. Thomas Jefferson University researchers have found that genomic analysis using…
Luke Skywalker’s bionic hand is a step closer to reality for amputees in this galaxy. Researchers at the Georgia Institute of Technology have created an ultrasonic sensor that allows amputees to control each of their prosthetic fingers individually. It provides fine motor hand gestures that aren’t possible with current commercially available devices. The first amputee to use it, a musician…
Researchers using CT scans and 3-D printing have created accurate, custom-designed prosthetic replacements for damaged parts of the middle ear, according to a study being presented at the annual meeting of the Radiological Society of North America (RSNA). The technique has the potential to improve a surgical procedure that often fails because of incorrectly sized prosthetic implants, researchers…
Everyone is unique – and so is human anatomy. Thus orthopaedics or implantology call for medical products that provide a perfect fit and demand is high for one-off components, or small production runs. At the same time, the materials used and manufacturing standards applied must fulfil extremely stringent quality control. This also holds for specialised surgical instruments and medical devices,…
Electrospun materials bring a spark of hope to a cardiovascular landscape darkened by setbacks for reabsorbable stents.
Which CRT patients can be ‘downgraded’ from a CRT-D device with defibrillator function to a CRT-P with just a pacemaker function? This, with two further current CRT issues – chronotropic incompetence and telemonitoring of CRT patients – featured prominently at the Europace-Cardiostim Congress in Vienna.
Columbia Engineers make major advance in helping the hearing impaired follow a conversation in a noisy environment - and bring cognitive hearing aids a step closer to reality.
Biotronik’s Home Monitoring is an award-winning remote cardiac monitoring system that automatically collects data from a patient’s cardiac device, enabling the physician to review cardiac function independently of in-office visits.
The association of biofilms with multi-drug resistance has highlighted the need for further understanding of biofilms and for anti-biofilm strategies.
Breast implants may impede an electrocardiogram (ECG) and could result in a false heart attack diagnosis, according to research by the European Heart Rhythm Association (EHRA), a registered branch of the European Society of Cardiology (ESC).
The implantation of knee and hip joints is considered one of the success stories of recent years. But periprosthetic joints infections (PJI) are one of the severe complications, with an infection rate of 2%. The probability of revision surgery increases with concomitant diseases such as rheumatoid arthritis, with fracture prosthesis or after previous surgery.
Good news for World Antibiotics Day on November 18th. As local substances carriers, antibiotic-loaded bone cements from Heraeus help in the battle against implant-associated infections in orthopaedics and trauma surgery to prevent infection. This is demonstrated by a new randomised study from Great Britain in which the use of double-loaded antibiotic bone cement following femoral head fracture…
Complex bone fractures are often set with titanium or steel screws and plates. However, if these remain in the body for some time, they can cause health problems. A new bioceramic screw nail has the capacity of replacing the currently used metal components. It can be easily introduced into bone and does not have to be removed.
CarThera, a French company based at the Brain and Spine Institute (ICM), that designs and develops innovative ultrasound-based medical devices to treat brain disorders, announces the publication on initial successes in disrupting the blood-brain barrier (BBB) with the use of ultrasound. This has been achieved in association with teams from the Assistance Publique-Hôpitaux de Paris (the Greater…
An amputee was able to feel smoothness and roughness in real-time with an artificial fingertip that was surgically connected to nerves in his upper arm. Moreover, the nerves of non-amputees can also be stimulated to feel roughness, without the need of surgery, meaning that prosthetic touch for amputees can now be developed and safely tested on intact individuals.
Researchers from Charité – Universitätsmedizin Berlin and EPFL, Lausanne have succeeded in restoring motor function following spinal cord injury. The researchers were able to show that coordinated muscle movement is the result of alternating activation patterns emanating from the spinal cord. Newly-developed implants, which use electrical stimulation to mimic these signals, were used to…
Studies are underway to determine if a new modular partial wrist replacement will allow for better movement and last longer than traditional implants for people seeking relief from painful wrist arthritis. Although current options such as total wrist replacement and wrist fusion can alleviate pain, patients are often limited in performing certain activities after surgery.
By implanting electrodes in the brain tissue one can stimulate or capture signals from different areas of the brain. These types of brain implants, or neuro-prostheses as they are sometimes called, are used to treat Parkinson's disease and other neurological diseases.
