Reforming surgical procedures with 3D printing hubs in hospitals

Increasingly, hospitals use 3D printing in surgery because the technology can enable fast, unique production of patient-tailored tools at relatively low costs. ‘As the technology itself is developing and accelerating at a fast pace, hospitals may be left behind if they choose not to adopt these advances,’ said Limor Haviv, surgical 3D printing designer at 3D4OP. Today, 3D printing is used in…

'Soft' 3D printing could jump-start creation of tiny medical devices

Researchers at the U.S. National Institute of Standards and Technology (NIST) have developed a new method of 3D-printing gels and other soft materials. Published in a new paper, it has the potential to create complex structures with nanometer-scale precision. Because many gels are compatible with living cells, the new method could jump-start the production of soft tiny medical devices such as…

Endoprothetic risk: Metals from implants can accumulate in bone tissue

Using highly complex analytical techniques, a group of researchers from Charité – Universitätsmedizin Berlin were able to observe in detail how different metals are released from joint implants and accumulate in the surrounding bone tissue. Findings showed a steady release of metals from various implant components. In contrast to previous assumptions, this was not related to the degree of…

Can special coatings reduce complications after implant surgery?

New coatings on implants could help make them more compatible. Researchers at the Martin Luther University Halle-Wittenberg (MLU) have developed a new method of applying anti-inflammatory substances to implants in order to inhibit undesirable inflammatory reactions in the body. Their study was recently published in the "International Journal of Molecular Sciences".

New heart valve could transform open heart surgery

A new polymeric heart valve with a life span potentially longer than current artificial valves that would also prevent the need for the millions of patients with diseased heart valves to require life-long blood thinning tablets has been developed by scientists at the universities of Bristol and Cambridge. The team's latest in-vitro results, published in Biomaterials Science, suggest that the…

Developing self-healing bone replacements

Our body is able to treat many injuries and wounds all by itself. Self-healing powers repair skin abrasions and enable bones to grow back together. However, doctors often have to lend a helping hand to repair bones after a fracture or due to a defect. Increasingly, bone replacement materials are being used, which partially or completely restore the form and function of the bone at the site of the…

VR training to improve hip replacement surgery

More than 200,000 patients undergo hip replacement surgery in Germany each year. To avoid complications and extend the lifespan of the artificial joint, the implants must be fitted precisely in the acetabulum (hip socket). The procedure, particularly milling the acetabulum, is not only difficult but also the technique is difficult to teach and train. This is where HIPS…

Using iPS cells to fight transplant rejection

Scientists suggest a new strategy that uses induced pluripotent stem cells (iPSCs) to regulate immune reaction to transplanted tissues. The team, led by Professor Ken-ichiro Seino of Hokkaido University’s Institute for Genetic Medicine, found that thymic epithelium cells derived from mouse induced pluripotent stem cells (iPSCs) can regulate immune response to skin grafts, extending their…

Promising approach for breast regeneration

A team of researchers from Osaka University, Kyoto Prefectural University of Medicine, and Toppan Printing Co., Ltd. succeeded in reconstructing adipose tissue balls (“mini-breasts”) with a functional vascular network using patient-derived cells, achieving a high graft survival rate in small animal models. So far, silicone breast implants were primarily used in breast reconstruction following…

Challenges of periprosthetic infection

Periprosthetic joint infection (PJI) is on the increase internationally. In Germany, for example, around 14,500 cases of PJI in hip and knee replacements occur annually. 5,100 of those are caused by multidrug resistant pathogens. ‘Eighty-seven percent of those affected die within five years,’ orthopaedic surgeon Professor Rudolf Ascherl MD pointed out during the Heraeus Symposium held at the…

Nano-patch stores medical information under the skin

Every year, a lack of vaccination leads to about 1.5 million preventable deaths, primarily in developing nations. One factor that makes vaccination campaigns in those nations more difficult is that there is little infrastructure for storing medical records, so there’s often no easy way to determine who needs a particular vaccine. Researchers at the Massachusetts Institute of Technology (MIT)…

Implantable cardiac monitor gets diagnosis in just three days

It started as a fairly typical case: The 79-year-old patient had suffered unexplained dizziness for years. To diagnose why, the cardiology team at Sweden’s Kalmar Hospital performed echocardiograms, Holter ECGs and other tests. However, these tests showed normal sinus rhythm and thus were inconclusive.
