Patients who received a DePuy ASR hip replacement, are experiencing a higher than normal failure rate, resulting in the need for further revision surgery. The failure of the device can happen as soon as one year after initial replacement surgery. This could cause devastating hip pain, and potentially require additional surgery to replace the metal-on-metal hip implant. Patients report symptoms of severe pain, swelling, and loss of mobility.
On August 26, 2010, DePuy Orthopaedics announced a recall of their ASR XL Acetabular System and ASR Hip Resurfacing System used in replacement surgery, due to a 12% and 13% failure rate within the first five years of implant. At least 93,000 people worldwide have received one of the DePuy hip systems.
The ASR hip is made up of cobalt chrome ball and socket components that move against each other. Over time, the cobalt chrome material breaks down and microscopic particles are absorbed into the body. This metal ion release can damage tissue, muscles, bones and nerves around the hip.
It appears that the complications associated with the DePuy ASR hip may be linked to defects in the design of the hip implant. Orthopedic experts have suggested that the component has a narrow window for proper placement, which could explain the higher-than-expected DePuy ASR hip failure rate when compared with other types of hip replacement implants.
The manufacturer has announced that the DePuy ASR hip will be phased out in 2010. It appears that the risk of the problems associated with the hip replacement device was known for a period of time by DePuy. The New York Times has reported that the FDA has received about 300 complaints of DePuy ASR hip problems since the beginning of 2008. Most of those involved situations where patients required additional surgery to replace the DePuy ASR hip implant.
If you, or someone you love, received a DePuy ASR Hip Replacement System, and are experiencing complications, make sure to inform your physician immediately. He or she can also help to confirm whether or not your system falls within the recall. In addition, you should contact a personal injury atorney who is experienced in medical device litigation. You may be eligible for compensation due to injuries suffered as a result of the failed implant.
