Defective metal on metal hip replacement

Thyroid Dysfunction and Defective Metal on Metal Hip Replacements

Thyroid Dysfunction from Metal-on-Metal Hip Replacements

The thyroid is responsible for regulating the hormones that control our metabolism, cholesterol levels, muscle strength, weight, and even body temperature.
There are three categories of thyroid dysfunction. Hyperthyroidism is when the thyroid is overactive, hypothyroidism is when the thyroid is under-active, and lastly goiter, which is a swollen thyroid.
Doctors have linked thyroid dysfunction to defective metal-on-metal hip replacements. According to the FDA, “thyroid dysfunction, including neck discomfort, fatigue, weight gain or feeling cold,” is one of the systemic adverse effects that can happen with a metal-on-metal hip.

What Causes Thyroid Dysfunction?

In metal hip implants, the ball and the cup components rub against each other during regular daily use. This causes tiny metal particles to scrape off the implant and enter your body and wreak havoc.

According to a 2013 study by Prentice et. al, the tiny metal particles that are released can interfere with the body’s endocrine system, which includes the thyroid. Stated in the study, “prolonged exposure to cobalt can result in thyroid hyperplasia and hypothyroidism.” Similarly, a study by Steplen et. al notes that cobalt toxicity can affect the thyroid and induce hypothyroidism.

What is a “Systemic Effect” from Metal on Metal Hip Poisoning?

A systemic effect of metal on metal hips describes health problems that affect the entire body, instead of only the hip joint. Systemic injuries can happen when the microscopic metal ions flake off in the hip area and travel in the bloodstream to the rest of your body.  That’s how metal-on-metal metal hip can trigger metal poisoning reactions in your thyroid.

Sometimes the first symptoms of a metal on metal hip problem is a reaction in distant parts of the body, like the thyroid.

As attorneys litigating these cases, we strongly suspect thyroid problems can be caused by the toxic heavy metals released from these hip implants.  There is growing scientific and medical research pointing to this.

However, because the science connecting “systemic effects” to metal on metal hips is still fairly new, our ability to make these arguments in court is difficult.

We do find that hip replacement patients with systemic injuries, like thyroid problems, often have physical damage to their hip joint and surrounding muscle. That physical damage can go undetected for years with no symptoms like pain or swelling in the hip area.

Sometimes the first symptom of a metal on metal hip problem is a reaction in distant parts of the body, like the thyroid.

How is Thyroid Dysfunction from Metal-on-Metal Hip Replacements Treated?

For most side-effects of Metal-on-Metal hip implants, a common treatment is revision surgery of your metal-on-metal hip to remove and replace it with a new hip made of different materials.

Replacing your implant cuts off the supply of cobalt and chromium to your blood, which will prevent thyroid dysfunctions from worsening and, in some cases, may completely resolve the problem.

Depending on the severity of your thyroid problem, your doctor might also recommend standard thyroid dysfunction treatments in addition to revision surgery.

Some treatments for different thyroid conditions include synthetic hormone treatments, thyroid-slowing medications, radioactive iodine, thyroid removal surgery, and blood pressure medications.

What to do if you Suffer From Thyroid Dysfunction from a Metal-on-Metal Hip Replacement:

If you have been diagnosed with thyroid problems from your metal-on-metal hip implant, you should seek medical attention as soon as possible. Depending on your physician’s recommendations, they may also suggest you get a revision surgery.

You should also contact a lawyer with experience filing lawsuits against metal-on-metal hip manufacturers.

I can’t recommend this firm enough. They have an outstanding team that truly care for their clients…I have been awarded a fair six figure settlement.

When I say “they went to bat” for me…this Law Firm literally did just that. They persevered to bring the hard-nosed Manufacturer to settle and provide me some recompense for everything I had to endure which led to this suit.
