Diaphyseal fractures of the forearm include fractures of both bones or isolated ulnar and radial injuries. In terms of the level of integrity violation, there are fractures in the upper, middle and lower third of the forearm bones.
There are two types of fracture of the forearm bones: Monteja and Galeazzi. In the first case, a fracture of the ulna in the upper third occurs with a dislocation of the head of the radius. In the second case, fracture of the radius in the lower third with dislocation of the ulnar bone head.
Fracture of the elbow often occurs from a direct mechanism of injury (for example, falling on the elbow), but it can also happen with indirect violence - a break from a sharp contraction of the triceps or a fall on the wrist of the elbow in the elbow joint.
Fractures of the femur make up from 1 to 10.6% of all damage to the bones of the skeleton. They are divided into proximal fractures, diaphyseal and distal fractures.
Fractures of metacarpal bone account for 2.5% of all bone lesions in the skeleton. It should be noted that the mechanism of injury, the nature of the fracture and the type of displacement of injuries of the first metacarpal bone differ from the fractures of II-V metacarpal bones, so there is a need to consider these nosological forms separately.
Isolated fracture of the semilunar bone is extremely rare. Fracture of the semilunar bone occurs as a result of a fall on the wrist, withdrawn to the ulnar side.
Fractures of scaphoid bone occur, as a rule, when falling on an elongated arm, with an emphasis on the wrist. Usually, the bone breaks into two parts of approximately the same size, only a fractured fragment will break down if the tubercle fractures.
