A young marine lost all the sensation in his leg when he was in a humvee and hit by a roadside bomb in Iraq. That's when his sciatic nerve was severed. But now, a medical miracle is bringing the feeling back into that leg.
Sergeant Simard, 22, went to Johns Hopkins Medical Center for help. That's where they have been experimenting with nerve transplants. This week, in a tricky six hour operation, doctors there took nerves from other other parts of Simard's body and then re-attached them in his leg his brain and muscles were essentially reconnected with the transplanted nerves.
The nerves typically repair themselves at a speed of one centimeter a month, so it will still be several months before doctors know if this transplant was successful, but for patients like Sergeant Simard it brings new hope.
