Patient delighted after world's first full arm transplants

Six years ago a work accident had led to the amputation of both his arms.

"The feeling is indescribable," Merk, 54, said as he showed off the new limbs, which are being supported by a special "corset" while the healing continues. "Every day I gain more mobility."

Since the amputation, Merk was reliant on round-the-clock care. Two attempts to use prostheses failed.
