[Gun-shot fractures of the flat bones: mechanisms of development]
Abstract:
We studied experimental gun-shot fractures in the flat bones due to slow-speed bullets. We have found common features information of gun-shot fractures. Fragmentation of the bone tissue occurs within a Herz cone surrounded by ring-shape fissures as a result of crossing over of subsurface and median fissures. Invasion of the bullet into the bone thickness is accompanied with shift abruption of bone fragments, their parallel transfer, rotation and radial movement. In the injury with slow-speed blunt-pointed bullets the fragments move, as a rule, by parallel transfer and rotation. In the injury with sharp-pointed bullets, of a key importance is radial movement of the fragments changing characteristics of the gun-shot fracture.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Gross Anatomy of Bone
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in adults, it...
