Metal-on-Metal Hips Need Work More Quickly (CME/CE)
MedPageToday, 2012Finally, Smith and colleagues indicated that ceramic bearings would be most appropriate for patients needing large-head implants.
In an accompanying commentary, Art Sedrakyan, MD, PhD, of Weill Cornell Medical College in New York City, argued that the metal-on-metal implant story had revealed the inadequacy of medical device regulation in the U.S.
Sedrakyan called the FDA's 510(k) pathway "outdated and low-threshold" and suggested that it and its European counterparts "have created an environment that makes regulators vulnerable to errors."
He criticized the lack of rigorous requirements for pre- and postmarketing studies of most devices, including most hip implants, which meant that many thousands of metal-on-metal devices were placed before their propensity to fail became apparent.
An additional problem in the U.S., Sedrakyan suggested, is a political climate that pressures the FDA "not to stifle innovation."
it would not be surprising if metal-on-metal hip prostheses were just the tip of a device-safety iceberg yet to be revealed."
can look forward to "the burden of further surgical treatment as well as billions of dollars in costs to taxpayers."
