Defective Hip Implants

Experienced product liability attorneys for your defective hip implant case.

The attorneys at Florin|Roebig are investigating health complications such as metallosis caused to consumers who have undergone hip replacement surgery using a metal-on-metal hip implant. Lawsuits have alleged that the implants, composed of metals such as chromium and cobalt, are defective and damaging to patients since health complications linked to excessive levels of metal in the tissues, bones, and nervous system have been reported within the first four years after hip replacement surgery.

What is metallosis and how does it form?

Many patients who suffer from hip pain opt for surgery to replace the joint with an implant. Metal-on-metal hip implants are a popular choice among patients because they are made of metals such as chromium or cobalt which are considered more durable and corrosion-resistant than other materials. When the metal components of the implant rub together during day-to-day movement, the friction causes microscopic metal particles to shed into the bloodstream and surrounding tissues. Over time, this process can lead to a buildup of metal particles in the body that reaches toxic levels, causing a form of metal poisoning called metallosis. As an indicator of elevated levels of metal ions in the body after hip replacement, metallosis can be manifested by health problems including:

  • Bone and tissue death (necrosis)
  • Implant failure, loosening, or
  • Severe pain
  • Organ damage
  • Cardiomyopathy (heart problems)
  • Depression, anxiety, and other mental problems
  • Visual impairment (including blindness)
  • Cognitive issues
  • Nerve damage
  • Hearing loss
  • Infection

Doctors can diagnose patients with metallosis by performing a blood test to measure the levels of metal ions in the body. To treat the effects of metallosis after hip replacement, revision surgery has been widely used in order to replace the prosthetic with a safer product.

FDA Actions and product recalls

The U.S. Food and Drug Administration (FDA) warns that metal-on-metal implants pose unique risks due to the potential for metal ions to be released from wear of the implant. The agency refers to metallosis as an “adverse local tissue reaction. Despite massive manufacturer recalls and the risks associated with using metal-on-metal implants, the FDA has not banned the devices.

In an effort to limit the harm caused by metal-on-metal implants, the FDA tightened pre- and post-market regulations in 2016 by requiring all manufacturers to complete clinical trials to demonstrate safety and effectiveness before sales could continue. In 2018, DePuy, a division of Johnson & Johnson, announced that it would discontinue worldwide sales of its metal-on-metal products by August 31st. It is estimated that over 500,000 Americans have been fitted with metal-on-metal hip implants.

Thousands of injured patients have filed lawsuits against manufacturers for suffering from the defective design of metal-on-metal implants, the resulting revision surgeries, and the failure to warn the public about the risk of metallosis from use. Some examples of metal-on-metal hip implants include:

If you are contemplating a hip replacement surgery, ask your doctor what type of hip they plan to use, whether it is a metal-on-metal hip, and what are the long-term risks associated with that type of implant. If you already have a metal-on-metal prosthetic hip, and you are experiencing pain in that hip, you may want to consider being tested for metallosis. If you find that you do have metallosis and that a revision surgery is indicated, listen to the advice of your orthopedic surgeon.
