Why I have to move your broken arm.

So if you've ever broken your arm, you prolly wanna punch me in the nuts for having to move it while I'm xraying you. I don't blame you. If some smug jerk was trying to get me to move my broken arm and I didn't know why I'd wanna punch him in the nuts too. I'll explain why to you, and hopefully I won't lose my ability to have children next time I xray you.
        In order to tell the extent of your injury, we have to get multiple planes of view. Looking down from the top, I can see that your arm is broken, but I can't tell if the bones are pushed up, pushed down, or pushed into each other. By looking at things at an angle and then sideways, I can tell if you've shoved your radius and ulna above the fracture or below, which will tell the doctor how to treat you.
    That being said, there are ways that I can move my camera and film in order to get the views I need without having to move your arm much, so if you're in a lot of pain, ask the tech to try to do a shoot thru lateral view instead of moving your arm. If they don't know how or refuse to do it, then see the first paragraph of this post.
