![]() The authors screened 241 patients at a single center (one of limiting factors of this study) for the presence of cobalt in urine and blood. Systemic cobalt dissemination can result in brain hypometabolism and atrophy patients with levels of cobalt in blood as low as 1.1 ppb and in urine as low as 4.1 ppb are reported as having cobalt encephalopathy.” Periprosthetic cobalt-chrome metallosis is disseminated systemically and may result in arthro-prosthetic cobaltism. ”Īnd, they noted, “Wear and corrosion of cobalt-chrome joint implantations can result in periprosthetic tissue inflammation or necrosis, also known clinically as adverse reactions to metallic debris. (University of Alaska, University of Washington School of Medicine Anchorage Alaska, Tower Orthopedic and Joint Replacement Clinic, Aegis Imaging Consultants and EpiVac Consulting Services, respectively): “Cobalt is a mitochondrial toxin-encephalopathy and cardiomyopathy (cobaltism) may occur from iatrogenic, industrial, dietary, or arthro-prosthetic cobalt exposure.”įor the study, the authors first established a baseline level of cobalt levels in unexposed populations which: “In unexposed populations, the 95th percentile of cobalt levels in urine and blood are 1 part per billion (ppb) and 0.4 ppb, respectively. Here’s a link to that research letter.Īccording to authors Stephen S. In the JAMA research letter from six months ago, the authors summarized the issues with cobalt chrome large joint implants. Indeed, according to an August 2021 research letter in the Journal of the American Medical Association (JAMA), twenty million North Americans have cobalt-chrome arthro-prosthetic components.īut cobalt chrome has a checkered history. Pelt told OTW.Ī majority of knee implants are made with cobalt chrome in large part because of cobalt chrome’s 15-20-year longevity in the human body. “It’s time to remove cobalt chrome from the human body,” Dr. Pelt, M.D., Tenured Associate Professor in the Department of Orthopaedics at the University of Utah, Medical Director of the Orthopaedic and Trauma Unit at the University Hospital, and Chief Value Officer for the inpatient orthopaedic service line in the Department of Orthopaedics. Presenting Aurum® technology (as embodied in the Klassic® femur implant) is Christopher E. This is a must-attend meeting for all large joint surgeons. Thursday, March 24 | 1:30pm | Academy’s Innovation Theater | Chicago’s McCormick Center The company is introducing the Aurum® to the orthopedic community in the form of a new femur implant, brand named The Klassic®.Īurum® Presentation at AAOS: Date, Time and Location Exceptionally strong, lightweight titanium.More closely replicates the weight of native bone. ![]() ![]() No deliberate addition of common metal sensitizers such as nickel, cobalt, or chromium.“Our team has been working diligently for several years to find a material that can rival cobalt chrome in strength and hardness, and we are thrilled to introduce the first cobalt chrome alternative to our portfolio,” said Erin Hofmann, CEO of Total Joint Orthopedics.Īurum® is made using a patented ion beam enhanced deposition (IBED) process which ballistically bonds a titanium nitride (TiN) coating to a titanium femur substrate for significantly improved wear-resistance, abrasion-resistance, and surface hardness when compared to cobalt chrome. The company launching this new implant material is Utah-based Total Joint Orthopedics, Inc. It’s been decades since a truly new arthroplasty implant material was introduced at AAOS. if it meets all of its pre-launch promise, this modern application could well challenge cobalt chrome’s strength, hardness, and longevity and, in the process, establish a new standard for total knee arthroplasty implant materials. Brand named Aurum®, a novel implant coating process is being introduced to the orthopedic community at AAOS as a first step toward Total Joint Orthopedics, Inc.’s commitment to eliminate cobalt chrome in orthopedics. ![]()
