Metal on Metal hip implants have been around since the 1960s. While they were a gigantic leap forward in the treatment of hip failure for the vast number of folks who needed hip replacements, they didn’t come without risk. This first wave of metal on metal hip implants lasted until the 1980s when straight Metal on Metal was replaced with polyethelene and synthetic components due to high failure rates of the metal on metal. Later in the nineties, companies created a “second generation” of metal on metal devices, with a focus on younger patients in order to boost profits – the more implants sold, the more money the manufacturer makes.However, problems with these implants began to surface in the early 2000s, including high revision rates, metallosis (explained below), pseudotumors, along with a host of other dangerous complications. Despite these recognized safety risks, manufacturers continue to push them on the market despite the growing safety risks. Perhaps the most dangerous and well known risk is what’s called metallosis.
Metallosis, also known as metal poisoning, occurs when metallic debris accumulates in the body’s soft tissue. Usually, the condition refers to cobalt and chromium particles that absorb into tissue as a result of faulty metal orthopedic implants. High levels of cobalt in the body, also known as cobaltism, can cause damage to the body’s organs. Metal parts from orthopedic devices can shed small metal particles when they grind together. When metallosis occurs, the immune system identifies the metal ions as foreign bodies and aggressively attacks the soft tissue that contains them. Damaged and inflamed tissue can contribute to premature loosening of the orthopedic device. Metallosis can also lead to necrosis, which is characterized by extreme skin rash and death of skin cells.It also can lead to neurotoxicity, cardiomyopathy and Hypothyroidism.
Further, wear and debris of metal ions and particles released as a result of Metal on Metal articulation causes tissue destruction, fluid buildup, pseudotumors and bone destruction. Many of these injuries require revision surgery. Common adverse effects include pain and swelling, metal toxicity, and nerve and tissue damage. Other complications include:
When trying to figure out if you may be experiencing some of these complications, the first place to look would be to identify any symptoms you may be having. Symptoms can vary but the most common ones are difficulty walking, swelling, numbness, and grinding/clicking/popping/squeaking surrounding the hip replacement.
As noted above, there are a variety of hip replacements, manufactured by several different companies, that can cause these injuries. If you or a loved one has received a metal on metal hip implant from any of the above companies (DEPUY – ASR AND PINNACLE, ZIMMER – DUROM, STRYKER – REJUVENAT, WRIGHT – CONSERVE AND PRO FEMUR, BIOMET – MAGNUN M2A. ,SMITH & NEPHEW – R3 LINER AND (BIRMINGHAM) BHR), or are unsure of the company, please feel free to reach out to Zaner Harden Law where we will provide you a free consultation and help determine whether you may have an actionable claim.
The reality is that each different Metal on Metal hip replacement, manufactured by each different company, has its own unique and particular side effects and causes of those side effects. While general information is provided on this page, it iss important that your attorney understands the difference between the implants and knows how to pursue a claim accordingly. The different manufacturers have been brought to task in different courts and in different states (while some are about to be brought into court).
