Maxence, a 6-year-old French boy who was born without a right hand, tries on his new 3-D-printed hand given to him by the American foundation e-NABLE Association on Monday. The artificial hand, which is worn like a glove, grasps objects when the user bends his or her wrist, and is attached without surgery. The prosthesis does not allow for more precise activities like tying shoes, but does allow users to do things like riding on swings or a scooter that are difficult to do without fingers.SD-Agencies
