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!
