Risks of DePuy Pinnacle Hip Implant

DePuy Pinnacle Hip Replacement

Numerous lawsuits have been filed regarding the DePuy Pinnacle Hip Implant. The lawsuits claim that its manufacturer, DePuy Orthopaedics, did not properly warn the public about the serious risks associated with using this device. The lawsuits claim that DePuy bypassed rigorous FDA testing by comparing it to older hip replacement devices that the company manufactured.

A typical hip replacement system consists of a number of components: the implant, meant to mimic the body’s hip joint; a metal ball; a cushion liner; and a cup-like structure. The DePuy Pinnacle has a different design that puts the metal ball directly in contact with a metal liner. Both the ball and the liner are made of cobalt-chromium metal.

Studies show that the metal-on-metal construction, like that in the DePuy Pinnacle,  creates serious problems. The friction between cobalt-chromium ball and lining can cause a release of metal particles into the surrounding tissue.  This inherent design problem can lead to an increased failure rate, metallosis, infection, dislocation and immobility. The FDA has received over 1,800 adverse event reports related to Pinnacle components. At least 800 of these reports identify the metal liner as a part of the problem. In fact, the rate of adverse event reposts given to the FDA has steadily increased since its inception in 2001. 

Patients who have DePuy Pinnacle metal-on-metal hip implant failures often experience one or more of the following side effects:

  • Pain in the hip region
  • Inability to walk/difficulty walking
  • Limited flexibility
  • Swelling/inflammation in the hip region

Patients often experience a variety of medical symptoms from metallosis that include:

  • Pseudotumors
  • Pain in the hip region
  • Tissue degradation
  • Nerve problems including weakness and numbness
  • Bone problems including unexplained fractures
