Concerns about the DePuy ASR and other Metal-on-Metal Hip Devices Continues

Law Offices of John David Hart seeks justice for victims of defective hip implants.

FORT WORTH, TEXAS—John David Hart, of the Law Offices of John David Hart, recently filed another DePuy ASR lawsuit seeking recovery for victims of failed hip implant devices.  The firm has now filed over sixty cases.  The cases are pending in the United States District Court for the Northern District of Ohio before Judge David Katz.  Judge Katz is presiding over the multi-district litigation pertaining to the DePuy ASR. 

The Eighth Annual Report 2011 issued by the National Joint Registry for England and Wales cited that a version of the Johnson & Johnson ASR all-metal hip device sold in Britain has failed in approximately one-third of the 2,100 patients followed by the joint registry in the past six years.  Approximately 17% of the individuals in this same group have experienced device failure at the five-year mark. These alarming failure rates have strong implications for U.S. patients implanted with the similar ASR metal hip device.

The British registry further reflects that all-metal hip devices in general have a higher rate of early failure when compared to other types of hip devices manufactured with a combination of different materials (such as metal and plastic). In the past year, the U.S. has further scrutinized all-metal hip implants. The FDA, in particular, has required all-metal hip implant device manufacturers to conduct studies examining the increased failure rates in this type of hip implant.

According to the British report, the release of chromium and cobalt particles into the blood is one of the causes of the increase in early failure rates of all-metal hip devices. Although the release of metal into the body may not be life threatening, it has the potential to cause injuries that can further debilitate hip replacement patients.

“The number of people who have been harmed by the defective DePuy ASR metal-on-metal hip device is staggering,” said attorney Hart.  “I will continue to aggressively seek justice and fair compensation for my clients that have been injured as a result of these unsafe medical devices.”
