In responding to the growing number of complaints concerning metal-on-metal hip replacements, the FDA has responded in a two-fold manner. A few months ago, the governmental agency ordered all metal-on-metal hip replacement manufacturers to provide them with failure data and required them to contact patients who’ve received such hip replacements. Now, the FDA has published new information on its website concerning symptoms and signs of metallosis, a condition where metal fragments from the hip device enter the bloodstream. These metal fragments are loosened and fragment due to the wear and tear of the metal-on-metal friction caused by joint motion.
The new information should prove very helpful for patients who have a metal-on-metal hip replacement but don’t know if they are susceptible to metallosis or hip failure. In publishing the new information and making it accessible to the general public, the FDA has provided a real benefit to those who are concerned about their hip replacement. Here’s what they say in a nutshell:
Among the warning signs of such systemic reactions, according to the FDA:
• Chest pain
• Shortness of breath
• Neuropathies
• Visual or hearing disturbance
• Fatigue
• Weight gain
• Abnormal feelings of cold
• Urinary trouble
Patients with suspected adverse reactions should receive blood tests — to check for cobalt or chromium ions.
If you have a metal-on-metal hip replacement or aren’t sure what type of hip you have and are experiencing any of the symptoms or conditions mentioned above, check with your doctor and refer him to the FDA website.
