Yeah, the first thing he did after Braeden released him was grab his finger and hold it to his hand. After that he *appeared* to have ten fingers but I didn't get a good look (or really remember to count... okay, I admit it! :P)

So, my guess is that werewolves cannot regrow limbs however the accelerated healing allows them to reattach limbs and appendages.
