Approximately 25-30% of people have a hitchhiker's thumb, which is characterized by the ability to bend the tip of the thumb backwards at an angle of 90 degrees or more. It is an inherited trait caused by a genetic variation in the joint of the thumb.

you can have two types of thumbs, hitchhiker, or regular. (i guess that is what it is called, there may be some special name I am unaware of) Regular thumbs go straight up, hitchhiker thumbs curve back towards the shoulder, (if you were to stick your hand out to the side and put your thumb up) Hope this helps.
