Cobalt Poisoning Metallosis

Has your metal-on-metal hip implant failed prematurely? Have you suffered from pain, inflammation, difficulty walking, or developed non-cancerous tumors (cysts) since receiving your metal-on-metal hip implant? You could be the victim of cobaltism, or cobalt poisoning, from your metal-on-metal hip implant. Cobalt poisoning results when the metal components of an implant begin to wear and microscopic metal shards are absorbed into the blood stream and infiltrate the organs. The tissue damage that results from cobalt poisoning can complicate future revision surgeries intended to replace the damaged metal-on-metal hip implant.

Cobalt poisoning is extremely serious. Left untreated, it can result in tinnitus (ringing in the ears), vertigo, deafness, blindness, optic nerve atrophy, convulsions, headaches, peripheral neuropathy, cardiomyopathy, hypothyroidism, and cognitive problems, including dementia. Our cobalt poisoning lawyers are investigating the link between metal-on-metal hip implants. Some metal devices sold in the US include Wright Medical’s CONSERVE Total Hip System, Biomet’s M2a Metal Hip, Zimmer Orthopedics’ Metasul, and DePuy Orthopaedic’s now-recalled ASR XL Acetabular Hip Replacement System. If you received one of these, or another metal-on-metal hip implant, and your health has deteriorated, our cobalt poisoning lawyers want to hear from you today.

Cobalt Poisoning and Metal-on-Metal Hip Implants

A metal-on-metal hip implant is made of chromium and cobalt, and consists of a cup that’s implanted into the hip with a ball joint that connects to the leg. According to a New York Times report published in March 2010, metal-on-metal hip implants have been used in about one-third of the approximately 250,000 hip replacements performed annually in this country. However, many of the nation’s leading orthopedic surgeons have reduced or stopped use of these devices because of concerns that they can cause severe tissue and bone damage. When they wear, metal particles from these hip implants can infiltrate organs and tissues, and may even create large, painful cysts. The limited studies conducted so far on metal-on-metal hip implants estimate that 1 to 3 percent of implant recipients could be affected by the problem.

An October 2010 article published in The Journal of Bone and Joint Surgery linked metal-on-metal hip implants to cobalt poisoning. The article described two patients from Alaska who developed the condition after receiving DePuy ASR metal-on-metal hip implants. Both were “fit, well, forty-nine-year-old men at the time of metal-on-metal arthroplasty with ASR implants,” the article said. Thirty months after surgery, one patient’s blood cobalt level was 122 µg/L, while the second patient’s measured 23 µg/L one year after receiving a metal-on-metal implant. According to the study’s authors, normal serum cobalt level is 0.19 µg/L, and 95 percent of those who are unexposed to cobalt have a value of <0.41 µg/L.

Within one year of the hip implant surgery, both patients experienced symptoms of persistent hip pain and shortness of breath as the microscopic metallic particles from the hip implant were released into the bloodstream and tissues. Two years after the hip implantation, the patients in the study experienced even more symptoms of cobaltism, which can include irritability, fatigue, tinnitus, hearing loss, headaches, loss of coordination, cognitive decline, and depression. After revision surgeries, the patients’ symptoms improved. The authors called for a larger group study to define the prevalence and spectrum of cobalt poisoning due to hip replacement surgery.

Hip replacement patients should be relatively pain-free three months after surgery. Any new pain or increase in pain at that point should be promptly communicated to your surgeon, as it may indicate a complication. Signs that you may be the victim of a failed metal-on-metal hip implant and cobalt poisoning include:

  • Swelling, Extreme Pain & Discomfort
  • Dislocation of Implant
  • Clicking, Popping or Grinding
  • Loosening of the Implant
  • Unexplained Hip Pain
  • Thigh Pain or Groin Pain
  • Pain with Walking
  • Pain Rising from a Seated Position
  • Pain with Weight Bearing
