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.
