Concerns about shortages of orthopaedic implants due to the EU Medical Device Regulation
The German Society for Endoprosthetics (AE) is concerned about potential shortages of artificial hip and knee joints. Bureaucratic hurdles urgently need to be removed, as otherwise the EU Medical Device Regulation (MDR) would increasingly jeopardize patient safety, it said today. The MDR, which came into force in 2021, has been...
Rehabilitation after leg amputation with transcutaneous osseointegrated prostheses
Traditional prostheses after limb amputations allow only a part of the affected persons to achieve the desired and desired autonomous mobility. In analogy to dental implants, systems have been developed that allow the coupling of an exoprosthesis to a force carrier integrated in the bone and transmitted through the skin....
Detect Endoprosthesis loosening at an early stage
Our society is aging. So the number of people who need an artificial hip joint, for example, is also rising. This can have long-term consequences for the healthcare system. "In more than ten percent of cases, loosening of the implanted prosthesis occurs within 15 years after hip surgery" (Alexander Franck,...
Bioactive bone replacement from the 3D printer
The treatment of bone tumors or severe bone injuries often poses major problems for medicine. Titanium, for example, is used as a bone replacement material. There is a risk that the rigid implant will loosen, leading to long-term problems. A second therapeutic approach, he said, is to remove bone material...
Frequency of transfusions in endoprosthetics reduced
Endoprosthetic surgeries often involve significant blood loss and result in up to 46 percent of patients requiring a blood transfusion during or after surgery. After various changes to procedures during and after surgery, surgical teams can now not only avoid the sometimes high blood loss associated with inserting a knee...
Complication rate after hip and knee arthroplasty related to obesity
Obesity prevalence has almost tripled worldwide since 1975 (Germany). Obesity is a risk factor for osteoarthritis of the hip and even more so of the knee. Compared to non-obese individuals, they have a higher risk of complications. The objective of this study was to analyze the association between obesity and...
Internationally different ratios for hip endoprostheses.
According to the OECD, there are 204 hip replacements per 100,000 people in the USA, 315 in Germany, 128 in Spain and 68 in Israel. How long do patients in Germany and the United States stay in the hospital and rehab after hip replacement surgery? In Germany, about 10 nights...
Bilateral simultaneous hip arthroplasty shows comparable early outcome
Bilateral simultaneous hip arthroplasty shows comparable early outcome and complication rate as staged bilateral hip arthroplasty for patients scored ASA 1-3 if performed by a high-volume surgeon No significant differences were found concerning the complication rate or early inpatient rehabilitation.Conclusion: Simultaneous bilateral hip arthroplasty in patients with symptomatic bilateral hip osteoarthritis...
Total Ankle Replacement Versus Arthrodesis for End-Stage Ankle Osteoarthritis
End-stage ankle osteoarthritis causes severe pain and disability. There are no randomized trials comparing the 2 main surgical treatments: total ankle replacement (TAR) and ankle fusion (AF). Between 6 March 2015 and 10 January 2019, a total of 303 patients were randomly assigned. At 52 weeks, the scores improved for...
