Loss of limbs is unfortunately not an uncommon scenario for soldiers in combat.
But new prosthetic technology is helping those who lose their legs to walk again.
Staff Sergeant Heath Calhoun lost both of his legs while serving in Iraq, when a rocket ripped through the truck he was riding in.
"I looked down and I could tell that my uniform was ripped pretty bad, and was bleeding pretty badly. When I woke up after surgery, a doc came in and told me both of my legs were gone."
Thanks to advances in prosthetic technology, Calhoun not only has new legs, but is able to lead a lifestyle similar to what he enjoyed before. His previous pair of prosthetics were a more difficult adjustment for those with above-the-knee amputations.
"With the old ones, I'd walk up, throw my legs up, shift and come around. With the new one I can bend the knee."
The legs are computerized prosthetics that allow him to walk, run, play golf--even cartwheel. The prosthetics are able to sense when to lock or when to swing freely.
