Patients that have received metal-on-metal hip implant devices are far more likely to need revision surgery, an article by verywell.com states.
Jonathan Cluett, MD, contributed his expertise in an article published by the website providing information to patients that have received metal-on-metal hip implants, and what they should do if they are experiencing problems.
Metal-on-Metal hip implant designs were recommended for patients with a more active lifestyle, based on claims the all-metal system was a better fit for their needs. But many of the implants were failing at an alarmingly high rate, whereas traditional models made of ceramics and polyethylene can last as long as 20 years or more. The failure of these metal hips has caused makers such as DePuy to face many lawsuits regarding the painful issues that patients are enduring.
Reports indicate metal-on-metal designs are failing in as little as five years, and many patients are experiencing adverse affects such as loosening, which is an especially dangerous issue for this design. As the parts of the device rub together during normal activities such as walking or running, the metal parts grind together, which may result in metal debris shedding into the body. According to Dr. Cluett, the body reacts to this microscopic debris with an immune response. This can lead to soft-tissue damage, as well as bone damage around the hip joint.
Dr. Cluett also states that “Patients with these metal-on-metal implants have also been found to have high levels of metal ions in their blood stream.” This release of metal can cause a type of blood poisoning called metallosis.
Dr. Cluett urges any patient that has received a metal-on-metal hip implant to please see their doctor regularly for evaluations and possibly regular surveillance tests because of these dangerous concerns.
