x-ray and fracture line

The typical x-ray appearances of fracture included

1. Radiolucent line
2. Radiopaque line if the fragments overlie one another
3. Discontinuity or deformity in the out line of the bone

The second is the most miss point when we interpreted film x-ray.
Why can we see more radiopaque line in fracture look at this figure below?

For example, the oblique fracture of mandible ,we will didn't notice in x-ray because it sometimes presented only slightly not notably more radiopaque line. (The fracture fragment was overlapped)

Another example, in submentovertex view, in fracture zygomatic arch that the arch was collapsed and overlapped, show only slightly increase of radiopaque and widening of arch than contralateral arch.

Next time if I 'm not forget I will show the example of these film x-ray, however the most important in diagnosis the fracture of head and neck bone was not x-ray, but clinical.
