Rib fracture CT film examination, can be observed through the following: first, rib fracture if there is no displacement, X-ray sometimes can not determine whether the fracture occurs, need to be examined by CT scan. Ordinary CT scan can find that the rib bone cortex is broken and there is a gap in the middle of the rib bone. Secondly, CT scan, especially three-dimensional CT scan, can also be used if the displacement of rib fracture is not obvious. Plain CT can find obvious misalignment of fracture breaks, shortening deformity, separation displacement and so on. And three-dimensional CT, can observe the displacement of the whole rib fracture from 360 degrees, and can determine whether there is a comminuted fracture.CT scan is of great significance for displaced multiple rib fracture, and can be used as a reference before surgery, and according to the results of the CT scan, to further determine the surgical treatment plan, which can recover the rib fracture.
