WASHINGTON, DC (WLBT) – The FDA is asking for more studies to be done on some types of artificial hips.

The order asks all producers of metal on metal hips to collect more follow up data on patients who received the device. The use of metal implants has declined over the past two years, because they haven’t worked in a large percentage of patients and some patients have developed serious health problems.

Manufacturers are expected to take blood samples from patients to determine the levels of metallic ion in their systems and calculate how often the devices are failing.
