More Hip Replacement Devices Recalled US-wide
Hip replacement surfacing has become one of the popular surgical operations performed in our times, online sources say. However, one type of hip implant in the metal-on-metal (MoM) hipcategory has sparked some concerns over safety. Implantation of metal-on-metal hip replacements sometimes results in failures that are attributed to adverse local tissue reactions, according to an article found at medpagetoday.com/Orthopedics/Orthopedics/39234. Potential safety issues associated with MoM hip systems include local complications, such as pseudotumors and aseptic lymphocytic vasculitis – associated lesions, early device failure and the need for revision surgery, and systemic complications from metal ion exposure. About 16,800 adverse events associated with metal-on-metal hip implants were reported from 2000 to 2011. More than 14,000 recipients required revision surgery to remove a failing metal-on-metal hip implant. These problems have provoked patients to file lawsuits against MoM implant manufacturers. Lawsuits that have been piling up across the United States had been consolidated into multidistrict litigation.
In MoM hip implants the metal ball and the metal cup slide against each other during walking or running. Metal shards may also be released from other parts of the implant where two implant components connect. Such metal flux may cause some tiny metal particles to wear off of the device around the implant, which may cause damage to bone and/or soft tissue surrounding the implant and joint. This is sometimes referred to as an “adverse local tissue reaction (ALTR)” or an “adverse reaction to metal debris (ARMD).”
In fact, there are a number of metal-on-metal hip implants that are being recalled by its manufacturers. A hip system may be recalled by the manufacturer for a number of reasons. If your device is recalled, this does not necessarily mean that the device needs to be removed and replaced. In some cases, the recall just calls for different or more frequent monitoring. It is important to discuss the reason for the recall with your surgeon to determine the most appropriate course of action. If you are unsure if your hip implant was recalled, consult with your orthopaedic surgeon. Additional information on the recall may be obtained from the manufacturer or from the Stryker Rejuvenate Modular hip device recall website.
