What are Symptoms of Metallosis or Hip Replacement Metal Toxicity from Cobalt, Chromium in the Blood?
Metal-on-metal hip replacement systems, like the recalled DePuy ASR hip, Depuy Pinnacle hip, Biomet M2A-Magnum hip, Wright Conserve hip and others, have been linked to a risk of metal poisoning or metallosis from particles of cobalt and chromium that are released into the blood as the metal components rub against each other.
The metal ions may lead to a reaction around the joint, cause deterioration of the tissue, loosen the artificial hip and result in other serious complications. In addition, as the metal enters the blood stream, it may cause a number of other health problems, potentially impacting the nervous system, heart and thyroid glands.
Some common symptoms of hip replacement metal poisoning may include:
- Hip or Groin Pain
- Difficulty Walking or Standing
- Inflammation or Swelling
- Loosening or Failure of the Metal Hip Replacement
- Development of Tumors
The lawyers at Saiontz & Kirk, P.A. represent individuals throughout the United States who are pursuing financial compensation through a metal hip replacement poisoning lawsuit after experiencing problems caused by the defective and dangerous design of the all-metal artificial hip systems.

HIP REPLACEMENT METALLOSIS FROM METAL IN BLOOD
Design problems with metal-on-metal hip implants, can cause dangerous levels of cobalt and chromium metal particles to enter the body. This can lead to metallosis, a type of blood poisoning, and genotoxicity, which can lead to genetic damage. Chromium and cobalt have also been linked to cancer, and could lead to the development of tumors. It can lead to aseptic fibrosis, local necrosis or even help to cause metallic corrosion and increase the chances of hip replacement failure.
In recent years, many types of metal-on-metal artificial hip systems have been linked to a high failure rate, which may result in the need for risky revision hip revision surgery. Although the manufacturers promoted these implants as stronger and more durable, it appears that they failed to adequately research the impact of metal ions entering the body from the artificial hip.
The metal hip replacement lawyers at Saiontz & Kirk, P.A. began investigating potential lawsuits for individuals with elevated cobalt and chromium levels in early 2010. Since that time, the risk of toxicity from metal-on-metal hip replacement systems has gained substantial attention among the medical community and national media.
In August 2010, a hip replacement recall was issued for the DePuy ASR system, after the manufacturer acknowledged that about one out of every 8 patients may experience problems with the hip within five years after receiving the implant. Since that time, estimates suggest that the DePuy ASR hip failure rate may be substantially higher.
In May 2011, the FDA asked manufacturers of all metal-on-metal hip systems to obtain more information about the levels at which metal in the blood from hip replacements become dangerous and how much metal the devices actually shed. The agency also now provides substantial information about the risk of metal toxicity for individuals who have a metal-on-metal hip implant.
More recently, the FDA has announced that the concerns about metal hip replacement toxicity will be discussed at a June 2012 meeting of the Center for Devices and Radiological Health (CDRH) Orthopedic Devices Panel. At that time, the committee will review the failure rates, testing for metal ion blood poisoning, imaging methods, local and systemic complications, patient risk factors and considerations for follow-up after surgery.
