I did a finger nearly like that... LOL, damn, I don't want to admit to this... I was reaching down the chute of my snowblower... Yeah yeah, it was running.... yeah, there's a sticker right there with a cartoon hand missing all it's fingers. Well, at least the vane impact smashed the fingertip away. If I had reached from the other side, it would have been chop city. I'll save my femur story for another day. (Hint: I set off metal detectors, every time!)
To the OP, very glad you had access to good care and therapy. Thumb is a tough one to be without, even for just a while.
