[The determination of the type of external exposure by rib fractures]

The paper deals with differential diagnosis of an external exposure (blow, compression) from rib fractures in chest trauma. New informative parameters of bone microdestruction in fracture zones which may serve as expert criteria for conditions of their formation are proposed. Registration of microfissures in thickness of rib compact plates and spongy substance on both sides of the basic fracture, their character, direction and original mosaic makes it possible to determine the type of an external exposure blow, compression) with high accuracy.
