National Joint Registry’s 2012 Report Advises Against Using Metal-On-Metal Hip Implants
Two years ago, the National Joint Registry (“NJR”) for England and Wales released data that spurred the DePuy ASR hip recall. The 2010 NJR report revealed that one out of eight DePuy ASR hip implants failed, requiring recipients to undergo revision surgery within five years of implantation. Today, the NJR released its 2012 report, announcing that metal-on-metal stemmed hip implants should not be used at all. The NJR summarized: “The data continues to support the conclusions drawn last year showing a markedly higher failure rate with metal-on-metal bearing surfaces particularly with stemmed metal-on-metal, but to a lesser degree with resurfacing hip arthroplasty.”
Data from the NJR came from over 1.2 million hip, knee, and ankle joint replacement procedures. Other findings from the 2011-2012 data on hip replacement surgery include:
• Metal-on-metal total hip replacements have poorer implant survival than other bearing surfaces; • Large head sizes are associated with higher revision rates in metal-on-metal total hip replacements; and • Women are more at risk for hip replacement failure than men.
The report advised that all patients with metal-on-metal hip implants should be carefully monitored, a recommendation keeping in line with prior suggestions from the British Orthopaedic Association and British Hip Society.
The NJR also reviewed data on whether there is a link between metal hip replacements and cancer. The report suggests that more long-term studies are needed to determine whether metallosis, a complication associated with metal hip implants, may cause cancer.
The NJR 2012 data also showed that DePuy ASR hip replacements still reign with exceptionally high failure rates. ASR resurfacing hip systems had a 24.2 percent revision rate within seven years. The DePuy Pinnacle metal-on-metal cup also had higher revision rates than other bearing surfaces.
The latest NJR report confirms what numerous studies and safety advisories already found regarding the dangers of metal-on-metal hip implants. The U.S. Food and Drug Administration (“FDA”) has received nearly 17,000 adverse event reports about metal-on-metal hip systems, with 14,121 reports of patients who had to undergo revision surgery to remove their defective implants. The FDA convened an expert panel on metal-on-metal hips in June 2012, and though they did not issue any official statements about the devices, many experts and orthopedic surgeons said during the meeting that they saw no reason to continue using metal-on-metal hip implants in light of the safety concerns.
