Parker McDonald Reviews British Medical Journal Findings Regarding Defective Hip Implants

Share Article

The British Medical Journal has just released its findings after extensive research of metal-on-metal implants, reports Parker McDonald Law.

Parker McDonald Law Firm reported today that new research from the British Medical Journal further confirms that DePuy Orthopaedics, and other metal-on-metal hip implant manufacturers, put patients in danger with products like the recalled DePuy ASR hip implant. The British Medical Journal just released its findings after extensive research of metal-on-metal implants.

The report, which was sponsored by the U.S. Food and Drug Administration, confirmed the increased probability that patients who received metal-on-metal implants were twice as likely to need corrective surgery over those implanted with a non-metal-on-metal device. According to a recent article from Thomson Reuters, the report analyzed the results of 18 studies including 3,139 patients and over 830,000 operations reported in registries.

There are more than 700,000 joint replacement surgeries performed each year in the United States. The report recognizes that around 270,000 of those are hip replacement procedures. The study shows that allmetal-on-metal hip implants show no noticeable signs of improvement over traditional implants and may actually put patients at an increased risk.

The U.S. Food and Drug Administration (FDA) sponsored the published report and worked closely with academic experts, and additionally reviewed all published literature and large orthopedic registries. Art Sedrakyan, a professor at Weill Cornell Medical College, noted that the report is not a final conclusion, but it is clear that metal-on-metal devices double the risk patients have of needing a revision procedure.

The DePuy hip implant recall in August of 2010 created heightened scrutiny over the materials used in replacement hips. Manufacturers have used metal, ceramic and plastic pieces to construct the ball-and-socket structure. The metal-on-metal combination was marketed to be more durable, but high failure rates and metal toxicity has compromised the health of thousands of patients.

In May of this year, the FDA issued 145 orders for post market surveillance studies to 21manufacturers of metal-on-metal hip systems, including Zimmer Holdings, DePuy, Wright Medical, Biomet, and Smith & Nephew. According to the FDA, data from the studies conducted will enable the agency to better understand metal-on-metal devices and their safety profiles.
