"Baltimore Orioles fans got quite a treat before Monday's Major League Baseball game between the Orioles and the Oakland Athletics. Hailey Dawson, an adorable 5-year-old Orioles fan, threw out the first pitch with her custom-made, 3D-printed robotic hand.
Hailey has Poland syndrome, a disorder that causes children to be born with either missing or abnormal muscles on one side of the chest wall. Many with Poland syndrome -- including Hailey -- are also born with abnormalities of the hand, making it difficult or impossible to use their hands without prosthetics.
Prosthetics aren't cheap -- the functional myoelectric hands can cost tens of thousands of dollars -- especially when they need to be replaced several times as a child grows. So, Hailey's family turned to the engineering department at the University of Nevada, Las Vegas (UNLV) for help." -Anthony Domanico, CNET
