British researchers want metal hip implants banned

More than 500,000 Americans are wearing a certain artificial hip implant that some are saying needs to be banned.

At issue is the metal on metal hip replacements. British researchers say they should be "banned" because there is "unequivocal evidence" that they will fail at a much higher rate than other types.

According to the study in the journal Lancet, the failure rate is particularly high for stemmed metal on metal hip implants with larger head sizes and those implanted in women. Scientists say in these cases failure rates are up to four times higher than other types of hip implants.

This study comes just 10 days after another British agency announced that these type of implants should be carefully monitored, particularly among young women.
