"If you get there in time, anything is possible," said Houston firefighter Devon Sharp.
The people in these photographs are living proof of that.
Marissa Rotenberry, 24, lost her right arm in a car accident.
"They called it a mashed extremity, which meant that all the bone and muscle and skin was just too damaged," Rotenberry said. "It was still attached when I got here, but then they decided to amputate it at Ben Taub."
Nurse Aubrey Deberry is the first person Marissa saw when she regained consciousness at Ben Taub.
"She's always had such a positive outlook from the get go," Deberry said. "When she came out of surgery and they amputated she just looks down and goes 'alright'. That was her attitude from the very beginning. She was already looking up how to do a pony tail with one arm."
Danny Lewis, 53, was operating a steel manufacturing machine when his hand got caught in the rotor feed.
"My hand from my forearm on down was hanging down to my knees still attached," Lewis said.
Here's the fire department crew that rushed Lewis to Ben Taub.
"We don't typically get to see the end result," said Houston firefighter Jason Beasley. "Very rarely do we get to actually meet the people and actually get to see their face."
"After everything is done, the treatment, the recovery, its great to see your work come to a good end," Sharp said.
