In late 2010, DePuy Orthopedics began a recall on its hip implants, which are known as the ASR XL Acetabular and ASR Hip Resurfacing systems. These implants are all-metal artificial hip implants, which were used in more than 40,000 patients nationwide from August 2005 to August 2010. Similarly, the DePuy Pinnacle implant with Pinnacle Metal Insert have been recalled as many of these implants have prematurely failed.
The devices are faulty due to design flaws. The first being that the device shell does not sit in the proper place in the hip and it resists bone growth. The friction caused by the metal hip ball rubbing with the metal hip socket causes small shavings of metal debris to be released in the tissue and blood. Metal flakes in surrounding tissue and blood can lead to a painful inflammatory reaction in the tissue as well as a high blood metal content.
Among data that has recently been released on the ills of metal-on-metal artificial hips are studies done by the Food and Drug Administration. One study found that up to one in two individuals with the implant may be forced to have revision surgery because of the extremely high premature failure rate associated with the DePuy ASR artificial hip implant. Similarly, the Food and Drug Administration released a statement admitting that there are various risks in these types of artificial hips as metal ions can wear off and cause damage to nearby tissue. Individuals who have any type of all-metal implant should understand potential risks and symptoms that may indicate that the implant is defective and not working properly. The most common symptoms reported include, but are not limited to:
- Implant dislocation
- Loosening of either implant or bone
- Fractured bone around implant
- Pain in related areas (groin, hip or leg)
- Swelling near hip joint
- Change in walking ability such as a limp
Patients filing lawsuits on these grounds have sought compensation for pain, suffering, physical injuries, cost of replacement surgery and other related costs that resulted from the failure of the DePuy hip implant.
