The tech at the immediate care facility saw it, but my ortho didn't when he reviewed it on a follow-up. I had to point out the bone and where it was before my ortho saw it. His response was basically "Oops" followed by removal of the temporary cast/sling and replacing all of that with a reinforced removable brace (which was awesome, because I could easily shower).
I broke my hand after dumping my bicycle taking a corner too fast on a training ride (I was doing around 25 mph) and losing traction under my rear tire. Rode home about 5 miles on that broken hand...
Thankfully it wasn't broken at all, it just hurt like hell for a week.
For as long as he is alive, he will have less range of motion in his right wrist than his left, barring advances in nanotechnology bone reconstruction or something.
Millions of years from now, when his body has broken down into petrochemicals, I suppose that yes, his wrist will then have a greater range of motion then it does now.
But that’s hardly relevant.
If that is his attitude - and the attitude of everyone around him - then that will likely be the case.
In 'reality' - whatever that means to you - plenty of folks have demonstrated that the body is malleable.
With work, ROM is restorable.
My brother fractured his scaphoid bone during a high school lacrosse game, and the doctor who x-rayed his wrist did not detect it.
He continued living an active life with a broken wrist (he has a high pain tolerance) for several months before the worsening pain sent him to an orthopedic specialist.
Being unaware of the fracture, he had done quite a lot of damage to the bones in his wrist, which wound up needing multiple surgeries and nearly 18 months (!) in a cast to fully heal. He also permanenly lost a bit of that wrist’s range of motion.
I welcome any tool that helps doctors not miss this sort of thing!
