In 2002, DePuy Orthopaedics along with Johnson & Johnson manufactured a hip implant sold under the name DePuy Pinnacle.
A typical total hip replacement system consists of four separate components: 1) a femoral stem; 2) a femoral head; 3) a liner; and 4) an acetabular shell. The DePuy Pinnacle hip is unique because some of the Pinnacle hips utilize a metal liner.
Hundreds of lawsuits have been filed alleging that the DePuy Pinnacle hips with the metal liner suffers from a design and manufacturing defect. Plaintiffs allege that the friction between the liner and the head cause excessive amounts of metallic particles, specifically cobalt and chromium, to wear from the surface of the insert or from the femoral head.
Although the Pinnacle liner has never been recalled, in 2013 DePuy announced that it was discontinuing the metal liners.
No. Many of the DePuy Pinnacle hips used a Polyethylene liner, which is not subject to the lawsuit.
Whenever a medical device is implanted during surgery, a detachable sticker is removed from the device packaging and placed in the patient’s medical record. This sticker has a bar code and identifies the make, model, and serial number of the enclosed parts. This product identification label will tell you exactly what type of components were implanted during your hip replacement surgery. Meshbesher & Spence will obtain these product identification stickers on your behalf from the implanting hospital free of charge.
If you received a DePuy Pinnacle hip with a metal liner, we recommend asking your doctor about a simple, inexpensive blood test to check your cobalt and chromium levels. If your levels are elevated, it could be a sign that your hip is failing. Cobalt and chromium is measured in “parts per billion” or ppb. Normal cobalt and chromium levels are less than 1ppb. Many people with Pinnacle metal inserts have been found to have cobalt and chromium many times higher than normal in their blood.
If you have elevated cobalt and chromium in your blood, your surgeon will likely order a Metal Artifact Reduction Sequence or “MARS” MRI. This is a special type of MRI that is designed to determine whether there is soft tissue damage in your hip or the development of pseudotumors (abnormal pockets of fluid). These soft tissue injuries will not show up on x-rays.
Unlike many firms who make big promises and then refer their cases to other attorneys, Meshbesher & Spence will handle your DePuy Pinnacle hip case from beginning to end.
The lawyers at Meshbesher & Spence have recovered well over $100 million for their drug and medical device clients over the past few years.
