Researchers develop ceramic resurfacing prosthesis for hip joint

January 4, 2021 | Europe | News

HERMSDORF, Germany: The hip resurfacing prosthesis currently used in surgeries is made from an alloy consisting of cobalt, chromium and molybdenum. However, this metal is not tolerated well by all patients, as some develop allergic reactions or infections. In some cases, the prosthesis may even need to be removed. Through the Ceramic Bonepreserver project, Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) has developed a new ceramic resurfacing prosthesis consisting of femoral cap and monobloc acetabulum, which have a higher biocompatibility—and are yet just as stable and strong as their metal counterparts.

Improved survival after bariatric surgery in patients with previous myocardial infarction

November 24, 2020 | Europe | News

STOCKHOLM, Sweden: Researchers at Karolinska Institutet and Danderyd Hospital have studied the risk of additional myocardial infarctions and early death in severely obese patients who underwent metabolic surgery following a myocardial event. The registry study, which included 1,018 individuals, showed a lower risk of additional myocardial infarctions and an improved survival rate that cannot be attributed solely to weight loss.

Bioceramic implant induces cranial regrowth and restores bone defects in oral cavity

November 16, 2020 | Europe | News

GOTHENBURG, Sweden: Large cranial reconstructions are being increasingly performed worldwide, but remain a substantial clinical challenge. Researchers from Sahlgrenska Academy at the University of Gothenburg, in cooperation with Karolinska Institutet in Stockholm and Uppsala University, have now developed a novel bioceramic implant. Study results show that it has been proved to stimulate regeneration of natural skull bone so that even large cranial defects can be repaired in a way which was previously not possible.

Bariatric surgery increases life expectancy of obese patients

November 9, 2020 | Europe | News

GOTHENBURG, Sweden: On average, patients who have undergone bariatric surgery live longer than those given conventional treatments, a recent study has shown. Compared with the general population, however, both groups’ excess mortality is high. The study results are based on the Swedish Obese Subjects (SOS) study, which started in 1987 and is led by Sahlgrenska Academy at the University of Gothenburg.

COVID-19 free hospital areas could save lives after surgery

October 27, 2020 | Europe | News

BIRMINGHAM, UK: For fear that patients may contract COVID-19 in hospitals, millions of operations around the world were cancelled during the first wave of the pandemic. If operations for cancer and other time-dependent diseases are delayed, they may progress to be untreatable. Setting up COVID-19 free hospital areas for surgical patients could save lives during the second wave of the pandemic, a new global study has revealed.

New research on surgery volumes for cataract operations

October 13, 2020 | Europe | News

GOTHENBURG, Sweden: In general, surgeons who perform numerous cataract operations each year encounter relatively few severe cases, which probably contributes to their lower complication rate, as shown by a study led by the University of Gothenburg. The study results have provided new evidence in the endeavour to further improve patient care.

Surgical robot systems to gain more autonomy

October 5, 2020 | Europe | News

KLAGENFURT, Austria: An important sub-area of minimally invasive surgery is interventional radiology. At present, robotic systems are only used to hold and position surgical instruments. A research project, led by the Alpen-Adria-Universität Klagenfurt, will now explore more advantages of surgical robots and increase their autonomy to support surgeons.

Endoprostheses constantly release metal particles into the body

September 24, 2020 | Europe | News

BERLIN, Germany: Using highly complex analytical techniques, researchers from Charité – Universitätsmedizin Berlin have been able to observe how different metals were released from joint implants and accumulated in the surrounding bone tissue. Contrary to previous assumptions, a constant release of metals from various implant components occurred independently of mechanical stress. The study findings will help to optimise the materials used in implants and enhance their safety.

New method to improve quality control of donor organs

September 2, 2020 | Europe | News

GRAZ, Austria: Of 790 patients currently waiting for a donor organ in Austria, approximately three quarters need a new kidney, followed by patients in need of a liver. Particularly in the latter case, the organ quality of the available liver decreases with increasing donor age. To enable a faster and more comprehensive assessment of the organ quality needed for transplantation, researchers at the University of Graz and the Medical University of Graz are working together to develop a new imaging process, using the liver as test model.

Hip replacement surgery: Practice makes perfect

August 20, 2020 | Europe | News

GOTHENBURG, Sweden: A doctoral thesis at Sahlgrenska Academy at the University of Gothenburg has shown that the results of primary hip replacement surgery improve the more often a surgeon performs this operation annually. However, it did not make a significant difference whether the operating surgeon was a fully trained specialist in orthopaedics or a resident physician being trained as an orthopaedic specialist. The results may help to improve the quality for patients undergoing a hip replacement operation.
