Pioneering Surgery Makes a Prosthetic Foot Feel Like the Real Thing

May 30, 2018

(STAT News) – The key to making the bionic like the biological was combining a surgical advance with a technological one, the researchers say. Ewing — who mangled his left foot when he fell about 50 feet from a cliff he was scaling in the Cayman Islands — was the first person to undergo an entirely new kind of amputation, pioneered by Carty and MIT professor Hugh Herr. The engineers, meanwhile, developed a prosthetic foot that would enable two-way communication, with signals traveling from Ewing’s brain to his residual lower leg and into the bionic limb, and then back again.
