Also, when you see luceny on an Xray, is that indicative of more of a complete fracture held in place by the surrounding structure(s)/tissues or more likely a fissure that might be a partial/incomplete fracture that hasn't progressed fully through the bone? Are these common at the impact site of a projectile perforation through bone (radially extending from the perforation)?
I am just trying to get an idea of the fracture mechanics involved here so that when I see test results I have at least a simple, if not improved, understanding of what I am seeing.
This requires a long answer with some images. I don't want to mess up the OP's thread so I'll make another one. Stay tuned.
