That totally blows man. I hope your recovery is speedy and as painless as possible.
As for the deer, my father always told me to never swerve for an animal in the road, even if they are large.
Your chances of involving other people and vehicles are much greater and it's not worth killing yourself or someone else over a deer/rabbit/dog.
The only reason I would swerve would be if it were a human in my way.
Although sometimes you can't help the reaction.
