Anyone have a spare ulna?

To this day I have a bump of a bone sticks up a bit from the back of my right hand from a car crash around 2000. Used to have a huge triangular scar that you really have to look for now, and I didn't wear my watch on that wrist for nearly 10 years.

At 73, I've now got so many tweeks and hurts and glitches that it's sometimes hard to define one from the other.
