Health-related concerns surrounding metal-on-metal hip implants started when the device was believed harmful to users, published reports say.  More than a few orthopedic agencies have taken action on this matter. It was written in news write-ups that the US House of Representatives have requested an investigation on metal-on-metal hip replacements.
 
With the release of a more advanced hip design, the metal-on-metal (MoM) hip implant was set aside. Using of the MoM resumed when the metal-on-polyethylene resulted to loosening of its components.But as it was widely used, many recipients complained that the device caused them more harm.

On May 6 2011, the US Food and Drug Administration issued orders for postmarket surveillance studies to manufacturers of metal-on-metal hip systems.  As an added measure, plans for rectifications on the process of classifying all-metal hip systems are being worked on by the agency.  As cited in the FDA official website, “We have requested and will be reviewing device retrieval analyses from the manufacturers of the hip systems distributed in the US. This will help us understand how and why certain metal-on-metal implants fail over time.”

The US Drug Watchdog, too, has taken action by calling out the affected patients of the failed devices.  The US Drug Watchdog is the leading pharmaceutical in the country.It is dedicated to ensure the protection and safety of US consumers from marketed prescription medicines and medical devices. On a recent news report, the agency was quoted as saying “There is a huge problem with metal on metal artificial hip implant devices.”

The American Academy of Orthopedic Surgeons is active in their call for establishing a US joint registry. The academy trusts that a joint registry can routinely have a look at the implant’s functionality and promptly report unwanted instances that may arise from the device.Timely feedback on surgeon’s performance and long-term function of the device used will also be available with the AJRR.

Like the United States, Australia has also taken action on this health issue.  The national manager of Australia’s Therapeutic Goods Administration is also rooting for amendments in how government regulates marketing of medical devices in the country and in the world as well. He says that per government order, before a device is approved, clinicians will play a bigger role in assessing it first.

Device manufacturers have also taken their part in addressing the problem.  In 2010, a DePuy hip replacement recall was issued by the DePuy Orthopedics on their ASR XL Acetabular System and the ASR Hip Resurfacing System.With the combined efforts of the device makers, orthopedic authorities, surgeons and patients, solution on the metal-on-metal problem may soon be at hand.
