Funny pinkie finger on my right hand?

I've had a weird pinkie on my right hand for as long as I can remember. It's unable to be straightened and looks really weird when I salute or do something which requires flat-out fingers. It's really annoying and now the pinkie on my other hand is starting to curl up as well. I've noticed that several other people who are my friends and strangers also have this weird problem. Can anyone please tell me what's wrong with my finger and any ways which can be used to correct it?
