Crazed identical twins — one of them’s a surgeon — realize that there’s no rejection risks associated with transplanting bits of their bodies from twin to twin, and so they do. No word on what their mom thinks.

BME: The arm is amazing, but I’ve got to admit that this “alien finger” thing you’ve done is really something. It’s unlike anything I’ve ever seen before. It’s actually quite disconcerting!

RYAN: Yeah, we’re very proud of it. When people see the arm, they think it was an accident — transplants like this do get done every once in a while for medical reasons. The finger though, that’s art. We challenge anyone to take body art to a higher level.

BME: How did you pull this one off?

DAVE: First we removed the centre joint of my finger, along with the skin and just over an inch of overhanging tendon. Then we split Ryan’s finger at the end of the first joint. It was relatively easy to insert the extra joint, especially since we had so much extra tendon to play with. The amazing thing is that Ryan actually has feeling in the end of that finger now — the nerves were compatible!
