PARKER, Colo. -- Henry Barrett was playing tug-of-war at his Parker High School in October when he heard a “snap.”

Barrett said it only lasted four seconds, but that he almost immediately realized his right hand was bleeding and numb.

"It turned the muscles into hamburgers and severed 90 percent of the nerves. What wasn't severed was severely traumatized. Three bones were snapped clean in half," said Barrett.

It has been a long six months since the accident, but Barrett is doing better than doctors expected.

"I mean, I am already playing my flute and I've got good motion," said Barrett.

Barrett is also playing video games again and using his right hand to punch numbers in his calculator and to complete his homework.

The accident set the 11th-grader back nearly a semester in course work. He is now completing that work at home.

"There was a 40 percent chance of success. That's pretty low. That's less than 50 percent that his hand would come back, that it would be viable," said his father, Kevin Barrett.

Barrett's dad said his son has dealt with the situation well and that he is proud of his progress.

"I haven't given up. I refuse to give up," said Barrett.

A benefit for Barrett will be held Sunday at 4 p.m. at Swallow Hill, a folk school in Denver.

Proceeds from the event will go toward Barrett's medical co-pays and therapy.

Mitch Helfer was also injured in the tug-of-war accident and the money will benefit his recovery as well.
