Arguments Concerning the DePuy ASR Hip System

Posted by on Oct 11, 2013 in Personal Injury, Product Liability | 0 comments

In 2010, DePuy Orthopaedics, a holding company of Johnson & Johnson, recalled the widely used DePuy ASR hip implant. The recall was issued after numerous reports and lawsuits were filed against Johnson & Johnson for defective product design. Many of the recipients of a DePuy ASR hip were badly injured by the implant.

According to the website of the National Injury Law Center, the DePuy ASR ball-and-socket technology was made of cobalt and chromium alloy. The acetabulum shell (socket) and femoral head (ball) were separated by a flimsy polyethylene liner. In many cases, this liner wore down causing the cobalt and chromium to grind against one another. Not only did the grinding pain mimic the arthritic pre-operation condition, but it also put patients at risk for blood toxicity and damaged tissue.

Lawyers representing the victims of a defective DePuy ASR Hip System have mentioned that the scraping action of the metal-on-metal implant can cause damage to the tissue surrounding the joint. This damage can become so extensive that it eventually causes the surrounding tissue to die. Additionally, the scraping of the metal can raise the amount of metal ions in the bloodstream. This alteration to blood levels can affect a patient’s ability to fight infection as well as increase the risk for blood clotting complications.

In addition to physical complications to patients, many lawyers have argued that Johnson & Johnson was aware of the defective qualities of the DePuy hip implant before releasing it for market use. Johnson & Johnson has been accused of inadequate testing, the hiding of failure complaints, and the discarding of redesign efforts. The first federal trial over the DePuy Hip System began in September of 2013. Johnson & Johnson stands to lose around $3 billion dollars if they are held liable for the full extent of the damages.
