Is Joining the DePuy ASR Class Action Lawsuit still an Option for Recalled DePuy ASR Hip Implant Recipients With No Pain?

Andrew Sullo, Class Action Lead Counsel & Managing Partner at Sullo & Sullo is working hard to ensure that every single recipient of the DePuy ASR metal-on-metal hip implant is fully aware of both the recall on August 26, 2010 and the upcoming statute of limitations expiration for those who reside in states which implement the two-year statute. There are over 40,000 people who have received an ASR implant in the United States. The ASR was approved by theFDA in 2005 and began being widely used by surgeons who believed the metal-on-metal design would last much longer than the metal-on-ceramic or metal-on-polyethylene models.

Unfortunately, adverse health reports began pouring in with over 17,000 such reports received by the FDA regarding these all metal hip implants. Of those thousands of recipients, there are only approximately 6,000 who have joined into the MDL lawsuits against DePuy. While this might cause some to wonder if the risks of the ASR have been exaggerated, there are other factors involved. First of all, many recipients may not have heard the device was recalled or may truly have no idea what type of implant was used in their surgery. Second, many recipients of the ASR and other hip implant devices are senior citizens who may believe the symptoms they are experiencing are related to advancing age rather than attributing them to the ASR implant.

Finally, many of those who have not come forward to take part in the lawsuits state they are not having any problems with the ASR at present, so why would they sue the company? This is very flawed logic in this particular instance. Although the failure rate of the ASR was originally stated by DePuy to be in the 12-13% range—still much higher than the average of .5-5% failure rates—experts in the field have estimated that by six years following the initial surgery nearly 50% of the ASR hip implants will have failed and by eight years following the surgery a staggering 80% will have failed. When you look at those numbers you can see that it is highly likely that at least half of those thousands of people who have not joined into the lawsuit will suffer a hip failure. In fact, Andrew Sullo notes that “More than 50% of our ASR hip recipient docket has already received revisions.”

Chromium and Cobalt Poisoning: What are the Long Term Side Effects of Metallosis?

It is likely that the recipients of a metal-on-metal hip implant have heard about the possible consequences from the metal shavings which can be released into the body when the metal cup and ball rub against one another during normal activities. Tiny ions of cobalt and chromium shear off when the two surfaces meet and those ions can lodge in the surrounding tissues or can end up in the bloodstream. As more and more metal hip implant patients are realizing the seriousness of metal toxicity, blood testing for elevated levels of metals is increasing. In many cases patients have been found to have levels of cobalt and chromium in their bloodstream which are as much as a hundred times normal levels. 

Although slightly elevated levels of these metals are fairly normal for patients with metal-on-metal hip implants, extreme elevations can be very dangerous—and anxiety-producing for the patient. DePuy released a report indicating that concentrations of the metals greater than 7 parts per billion are cause for concern. The Mayo Clinic has set somewhat different reference values, stating that blood serum concentrations of chromium greater than 1ng/mL suggests significant wear of the metal implant while serum concentrations greater than 5.0 ng/mL of cobalt can be considered toxic and also suggest significant wear of the prosthesis. Remember that 1 PPB (part per billion) equals 1.0 ng/mL.

U.S. District Judge Expects DePuy MDL to Move Forward

A recent meeting between the Judge chosen to oversee the multi-district litigation in the DePuy Pinnacle hip implant case included attorneys from both sides. The goal of the meeting was to determine the most practical manner of handling the more than 1,000 current DePuy lawsuits. U.S. District Judge Ed Kinkeade—judge for the northern district of Texas—will use the MDL in the interest of expediting and coordinating these consolidated pre-trial proceedings. Unlike many MDL cases, the DePuy case appears to be moving forward with case management procedures expected in the next six weeks to two months.

The initial MDL trials in the DePuy Pinnacle cases are bellwether trials with a purpose of choosing representative cases from those filed to determine how juries will likely react to evidence which is common to all the cases. During a bellwether trial the judge and attorneys are able to gain knowledge which will be helpful in negotiating future DePuy lawsuits. The process dictates that representative attorneys will be chosen to try the DePuy bellwether trials; the knowledge gained from these trials will be extremely helpful in planning strategies and setting precedence for future Pinnacle cases. All attorneys involved in litigating the DePuy Pinnacle metal-on-metal hip implants will be watching the bellwether cases closely as well as the entire MDL.
