Don't give up for getting more motion back. I did the same type of break to my right pinky finger and also ended up with three screws in it. Mine was from having my hand gripping a sheep by the wool and she suddenly jumped the other direction before I could get my hand untangled. I also thought it was dislocated until I saw the x-rays. Anyway, my finger still isn't completely normal (did this a year ago), but it is almost fully functional. The only thing is that it doesn't straighten all the way and is fatter than my other pinky, but I don't even notice it anymore. As far as function goes, it was probably three or four months before I felt that it was pretty much back to normal. Hope yours ends up the same!
