Idaho man shows off new bionic arm made in Portland

Posted: Updated:

An Idaho man is now showing off his new bionic arm that was designed and built in Portland.

In July 2015, 25-year-old Sam Rosecrans was working in a saw mill in Idaho when he got his glove caught on a faulty conveyor belt.  He got stuck and the machine ripped off his arm, shoulder, shoulder blade and part of his clavicle – a severe and very rare kind of amputation.

Amazingly, Sam survived and after several months of healing, he contacted the staff at Advanced Arm Dynamics in southwest Portland.  He worked with them to design and build an electric prosthetic arm.

It runs on a battery and electrodes placed on Sam’s pectoral and back muscles sense what he wants to do and they move the arm, including fine finger movements.

Sam has already used it to hunt and fish back home in Idaho – hobbies he worried he may never be able to do again.

“I didn’t want to try to do everything with one hand. That seemed like it was just ridiculous,” said Sam. “And then trying to do some things one handed, you just can’t do it. So ultimately I wanted to be able to do things on my own again, have my independence back and not rely on everybody else. And having this is just the way to do it. It’s amazing. I can’t believe what I can actually do with this. I was skeptical at first, but after all the training I received, it’s fun and it works well.”

It cost between $130,000 and $180,000 to make Sam’s new arm. His therapists say he has more to learn, but his positive attitude is his greatest advantage.
