When the metal parts rub against each other, they release microscopic metal particles into Cobalt is known to produce a variety of symptoms in patients who accumulate a toxic amount in their blood. It is important to inform the technologist about any metal devices or implants before the scan. I was falling often, had several tests conducted and discovered when I went to my orthopedic surgeon that I have cobalt poisoning caused by the implant. e. This cohort study examines the association of cobalt-chrome arthroprosthetic components with adverse reactions to metallic debris, such as cobaltism. These alloys exhibit excellent mechanical properties, corrosion resistance, and wear behavior, making them a popular choice in the field of orthopedic implants. Demonstration of the implants’ safety is an intrinsic prerequisite for obtaining regulatory approval and placing those implants on the EU market. Constructed from various alloys, including titanium, cobalt-chromium, and stainless steel, these implants provide excellent stability and support to joints. Their compatibility with magnetic Orthopedic implants are the medical devices manufactured to support a damaged bone or to replace a missing joint or bone.
