I managed to talk my clinic into giving me copies of my x-rays on disc yesterday. Something like this "normally takes two to three days" I was told, but they grudgingly did it. In the first picture I outlined the broken piece of bone in red, and circled the area in yellow. In subsequent pics, the area is outlined in yellow only. So here's a picture of the original x-ray, taken back on July 2, about 10 days after my fall (click to embiggen).
And the same picture without the red, so the gap is more visible. This is the x-ray that the radiologist said was not a fracture.
Then we have the x-ray from two weeks later, on July 21. Pretty much the same from this angle.
This one shows a strange bump than neither my doc or I remarked on.
At this point I was put in a cast, because both doc and radiologist agreed it was a non-displaced fracture. After 4 weeks in the case, I had a third set of x-rays taken, on 8/19. Now I'm no doctor or radiologist, but it doesn't look like anything has changed. This is the shot that made my doctor say, "That looks like a non-union." and refer me to the hand guy.
I was showing these pictures to my daughters tonight, and Morgan said, "Dad, that's a pretty small piece of bone that's broken off. Do you need that?" And I thought, probably not. I'm sure the hand guy will totally agree.
