Parker Waichman LLP Comments on New Research Showing that Ultrasound is Useful for Detecting Pseudotumors in Patients with Metal-on-Metal Hip Implants

Researchers at the Hip Society Specialty Day Meeting in Chicago have presented findings showing that ultrasound can help diagnose pseudotumors in asymptomatic patients with metal-on-metal hip implants. Parker Waichman LLP comments on the findings and warns consumers to be aware of the risks of using all-metal hip replacements.

Parker Waichman LLP, a national law firm dedicated to protecting the rights of victims injured by defective medical devices, is commenting on the results of a prospective study presented at the Hip Society Specialty Day Meeting in Chicago. On April 17th, Orthopedics Today* reported that Dr. Donald S. Garbuz and his team had found that ultrasound is helpful for diagnosing pseudotumors in asymptomatic patients with large head metal-on-metal hip implants. Dr. Garbuz and his team won the Hip Society’s John Charnley Award for their research.

“These findings are helpful for patients with metal-on-metal hip implants,” said Daniel C. Burke, Senior Litigation Counsel at Parker Waichman LLP. “There are numerous lawsuits alleging that an all-metal hip replacement caused pseudotumors and other serious complications.” Mr. Burke said that the alleged flaws of the DePuy ASR are a prime example of why metal-on-metal hip implants are dangerous as a class of medical devices.

Parker Waichman LLP continues to offer free legal advice to patients implanted with such devices, and advises patients to speak with their doctors if they experience any symptoms or complications, such as:

  •     Metallosis, high levels of metal ions in the bloodstream
  •     Early failure, need for revision surgery
  •     Pain
  •     Swelling
  •     Difficulty walking, or a change in one’s walking ability

According to the Orthopedics Today report mentioned previously, the researchers analyzed 40 patients with metal-on-metal hip implants who underwent both ultrasound and metal artifact reduction sequence (MARS) MRIs. “Both tests, ultrasound and metal-reduction MRI, performed well for the detection of pseudotumors. However for screening or initial diagnosis, I would say to you that ultrasound in an experienced ultrasonographer’s hand would be the preferred method due to its 100% sensitivity and lower cost,” said Dr. Garbuz.

Metal-on-metal hip implants have raised safety concerns due to reports that the devices lead to early failure and other complications by releasing metal ions into the bloodstream and surrounding tissue. In 2010, Johnson & Johnson recalled 93,000 ASR metal-on-metal hip implants because of a high revision rate. J&J and its subsidiary DePuy face over 10,000 lawsuits alleging injuries from the hip device, according to Bloomberg.**

In January, the U.S. Food and Drug Administration (FDA***) issued new warnings about metal-on-metal hip implants, warning that the release of metallic debris can cause damage to the bone or soft tissue. Among other things, the agency recommended diagnostic imaging such as CT, MARS MRI and ultrasound in some symptomatic patients.

Parker Waichman LLP continues to offer free legal consultations to victims of the DePuy ASR and other metal-on-metal hip implant injuries.
