DePuy ASR Hip Replacement Recall
In the fall of 2010 DePuy Orthopaedics issued a recall of over 93,000 of its metal on metal hip replacement implants. The FDA began receiving complaints about these implant failures for more than 2 years prior to the recall. The recall involves two Depuy products, the ASR XL Acetabular System (a total hip replacement) and the ASR Hip Resurfacing System (a partial replacement system). Only the ASR XL Acetabular system was approved for use in the United States.
The problems related to these metal on metal implants include loosening of the joint and the collection of metal debris deposits in the tissue surrounding the joint. The metal deposits are caused by the metal ball scraping against the metal cup. These metal deposits can cause inflammation, pain in the hip joint and in the groin. In some cases the metal deposits can cause a condition known as metallosis and even pseudotumors.
While the ASR metal on metal systems has been recalled, the Pinnacle model has not yet been. Although a recall of the Pinnacle model has not been issued, this metal on metal model is the subject of lawsuits against the manufacturer. Keep posted for further updates on these developments.
