Metallosis is commonly referred to as metal poisoning, or cobalt/chromium poisoning. The condition occurs after metallic components from hip replacements rub against one another resulting in the accumulation of metal in the body’s soft tissue. This condition has also occurred in patients that are sensitive to the implant, or for other unknown reasons. Over the last 40 years, this condition has been observed in an estimated 5% of metal hip replacement implant patients.

The medical device injury attorneys at Di Pietro Partners are pursuing cases against certain manufacturers of metal hip implants. Many of these devices are/were defective, and exposed patients to unnecessary health risks including cobalt/chromium poisoning. Therefore, if you or a loved one are suffering from metallosis as a result of a defective hip implant, you may be eligible to file a metal hip replacement lawsuit.

Metallosis Symptoms

Certain metal on metal hip implants may cause pieces of metal to be worn off the device. The metal may cause damage to nearby bones and tissue.  According to the FDA, these metal particles may even enter the bloodstream and cause problems in a patient’s heart, nervous system, skin, and thyroid gland. Thus, metal pieces of ions from metal on metal hip replacements present serious health risks.

The FDA recommends that anyone who undergoes a metal-on-metal hip replacement surgery be on the lookout for symptoms which may indicate a problem with their implant.  These symptoms include:

  • Pseudo tumor
  • chest pain
  • shortness of breath
  • numbness
  • weakness
  • change in vision or hearing
  • fatigue
  • feeling cold
  • weight gain
  • change in urination habits

Patients who have any of these symptoms after a hip replacement surgery may be experiencing a reaction to the metal of the implant or an increase in the amount of metal in the bloodstream. You can find additional information about these symptoms on the FDA’s Information for Patients Who Have Metal-on-Metal Hip Implants.
