Professor Kay told the BBC: "The most awful thing for an upper limb reconstructive surgeon to do is to remove an arm - it's a dreadful thing to do.
"But by using the bits that would be discarded, you can pluck a little bit of comfort."
He said Tom's new shoulder will be able to support an artificial limb. "This will be a tremendous advantage."
Tom has battled cancer for three years. He hopes the success of his surgery will give hope to others. A hospital spokesman said this surgery was first performed in Japan, but Lemm's case was a first for Europe. Link -via Arbroath
