Avulsion fracture recovery

I have an avulsion fracture in the last digit of my middle finger. Doctor says it will probably be deformed for good. Anyone have any experience with a recovery from this? Some stuff I've read says flexing the last digit might now be difficult which is obviously problematic.

An avulsion fracture as described to me by the doc is where the extensor tendon, the one on the back of the finger, pulls away from the bone but instead of simply rupturing away from the bone it pulls a little piece of the bone off with it. It happened when the last digit hyper-flexed.

My bone set correctly and is healing, just curious if anyone has had trouble with one before.

I'm currently healing from this. I'll post an update on the other thread.
