Other medical equipment has gained attention, after the PIP implant issue and it is none other than metal-on-metal hip implants. Experts seem to be remaining confused as whether it should be recommended to patients or not.

Some of them were of the view that it's a modern alternative for plastic and ceramic replacements and others were of the view that it's toxic than other available methods, and should not be used. Recently, the U. S. Food and Drug Administration was of the view that still there are chances that the equipment can be brought into use.

About half a million people residing in the US are having metal hip replacements and for their safety, the FDA has asked its expert team to issue guidelines that will them at any given time. Dr. William Maisel, who is chief scientist for devices in FDA, was of the view that they have allowed the use of metal hip replacements, as there are many ways by which mental replacements can be used.

However, there is other set of group, which is against the idea of carrying out research on the equipment at the time when the product is available in the market for sale. "Keeping these metal-on-metal hips on the market for the next five to 10 years while research is conducted is not ethical", said Diana Zuckerman, who is heading the National Research Center for Women & Families.
