(Reuters) – the food and drug administration of

United States ( FDA) responded to the growing concern about

the safety of metal hip prosthesis saying that

undergo the devices to a review of two days of

length by experts, which could lead to fix

more rigorous standards.

The FDA announced that a panel will be meeting on 27 and 28 June

integrated Advisor by scientists, researchers, patients and

medical assisting regulators to decide if they are imposed

new standards of assessment and review requirements to

must be met before that one of these prostheses may

sold in United States.

“we are consulting with experts, doctors and scientists

“

external to discuss the recent information on these

devices, so that the Agency can continue to

“

reliable recommendations in terms of security”, indicated in

a release Dr. William Maisel, Deputy Director of science

of the Center for devices and health radiation of the FDA.

The actions of manufacturers of Orthopedic devices

-including Stryker Corp, Zimmer Holdings Inc and Johnson &

Johnson – fell after the announcement, made on Thursday.

Hip replacement surgery is a common procedure

and expensive that it seeks to provide greater mobility and pain relief to

persons with problems joints, including arthritis.

Each year, United States, occur in about

270,000 hip replacements, which represents almost 40 by

cent of all replacements joints, according to British

Medical Journal. Analysts point out that the procedure

can cost as much as $17,000.

But for years there has been growing evidence that the

totally metal implants fail in greater proportion than

systems using other materials. Patients that the

are also have been showing to have older

concentrations of ions of metal in their blood.

A recent study of the whole national register of

England and Wales showed that about 6 percent of the

people that they implanted the variety exclusively

metal needed additional surgery to replace or repair the

prosthesis after five years, compared with the 1.7 to the 2.3 by

% of who carried plastic or ceramic systems.

The announcement of the FDA follows an order of May 2011 from

the Agency required manufacturers of metal implants

collected more data on the safety of their devices.

The FDA said that the meeting posted on the Advisory panel

it will look at rates of failure, evidence of metal ions

methods for images, risk factors for patients,

follow-up surgeries and complications associated with the

hip with metallic prosthesis replacements.
