The FDA approved a new kind of prosthetic leg that should help more amputees walk

The U.S. Food and Drug Administration approved a new type of prosthetic leg Thursday that attaches directly to the patient's bone. Most prosthetics rely on a socket attached to the remaining part of the amputated limb, Popular Science reports. But that solution isn't viable for everyone, since not all amputees have enough of the limb left to use.

The Osseoanchored Prosthesis for the Rehabilitation of Amputees device implants a fixture directly into the bone through two surgical procedures. A 2014 study found amputees using it experienced increased mobility, comfort, and function. It also eliminated common socket problems like chafing and heat.

So far the FDA has only approved the new prosthetic for above-the-knee leg amputations, but the device can also be used for other leg, hand, and arm amputations.
