Metal On Metal Hip Implants Faqs In California Metal on metal hip implants have the same adverse effects as other types of hip implants, including infection, loosening, bone loss, device or bone fracture, and joint dislocation. in addition. Common symptoms of metallosis include hip or groin pain, numbness and swelling. metallosis is a type of metal poisoning that can occur as a side effect of joint replacement devices with metal components, such as metal on metal hip replacements or other metal implants. these devices are made from a blend of several metals, including chromium.
Nih Researchers Uncover Clues Related To Metal On Metal Hip Implants Metal on metal (mom) hip implants have unique risks in addition to the general risks of all hip implants. in mom hip implants, the metal ball and the metal cup slide against each other during. A metal on metal hip implant consists of a ball and cup made of a cobalt and chromium alloy. originally developed as a more durable alternative to implants with ceramic or polyethylene (plastic) components, mom implants proved to be the opposite. their high failure rate is likely due to loosening, which occurs when components detach from the bone. Abstract. the debate on how best to manage patients with metal on metal (mom) hip implants continues. with over 1 million patients affected worldwide, the impact is far reaching. the majority of the aggressive failures of mom hip implants have been dealt with by revision hip surgery, leaving patients with a much more indolent pattern of failure. Although the vast majority of patients with metal on metal hip replacement do well, a growing number of patients with mom thr have required revision surgery. over 93,000 mom thr have been recalled by an implant manufacturer. over 643,000 mom thr have been done in north america.

Case reports in the medical literature have suggested the potential for systemic effects of elevated metal ion levels resulting from device wear in metal on metal (mom) hip implants. these effects. When they work well, metal on metal hip resurfacing and total hip replacements give years of trouble free use with very low levels of wear. however, some metal on metal implants can fail, increasing the amount of wear and producing small amounts of debris. this debris is particles (ions) of cobalt and chromium that make up the implant.
