DePuy ASR Hip Implant Revision Surgery Reveals Damage Caused by Metal-on-Metal Hip Implant

Mar 19, 2012 | Parker Waichman LLP

Doctors who recently operated on a Massachusetts woman to remove a failed DePuy ASR Hip Implant discovered that the muscle surrounding her device was dead and dying, while other tissue was blackened from a reaction to toxic metal ions shed by the metal-on-metal hip implant known as metallosis.  The victim, Suzy Mansfield, was just 57 when she received her all-metal ASR Implant in 2009, following assurance from her doctor that a metal-on-metal hip implant was the best option for a young, active woman like herself.

According to NPR, like so many other people fitted with a DePuy ASR hip implant, Mansfield's failed within just a few years of implantation.  Not long after receiving the device, she began experiencing constant, burning pain that grew worse overtime. 

Meanwhile, the DePuy ASR hip implant was named in a worldwide recall in August 2010, after it was found that they were failing in about 12 percent of patients within five years. Realistically, a hip implant should last around 10-15 years.   A year after the DePuy ASR hip implant recall was issued, Mansfield said she discovered that she had received on of the devices.

Recently, she underwent surgery at Massachusetts General Hospital to have the failing implant removed and replaced.  "You can see here the yellowish discoloration of the tissue that is no longer functioning,” surgeon Young-min Kwon explained to an NPR reporter during the surgery.  The yellow tissue was dead and dying muscle.  Other tissue surrounding the implant was blackened due to metallosis.  All of the damage was caused by toxic metal ions leaking from Mansfield's DePuy ASR hip implant.

According to NPR, Kwon has given Mansfield a hopeful prognosis in the wake of her surgery.  Four days later, Mansfield was ready to leave the hospital, and full of hope that her ordeal was finally over.

"I'm going to actually be able to — I think, and fairly soon — have no pain," she told NPR.
