Born without her left arm below the elbow, 8-year-old Madeline "Mady" Gardner got the world's first multi-grip bionic arm. The sleek prosthetic was designed to be bright pink at Mady’s request. Developed by British company Open Bionics, which recently launched in the U.S., the "Hero Arm" is billed as the world's first multi-grip bionic arm for children as young as 8 years old. Mady is currently the youngest person in the U.S. to receive a multi-grip bionic arm.
