The dislocations of the brush and the individual components of its bones are rare. Most often, a dislocation of the semilunar bone occurs, and also brush dislocations distal to the first row of the wrist bones.
Subluxation of the head of the radius is most often seen in children aged 1 to 4 years. In this period, children often fall, and accompanying adults, trying to prevent falling, pull the child for his straightened arm.
Dislocations of the forearm make up 18-27% of all dislocations. In the elbow joint, simultaneous dislocation of both bones is possible, as well as isolated dislocation of the radial and ulnar bone. Depending on this, these types of dislocations of the forearm are distinguished.
The frequency of habitual dislocation after traumatic can reach 60%. On average, it is 22.4%. Sometimes repeated dislocations arise without special violence - it is enough to withdraw and rotate the shoulder outwards.
Older dislocation - dislocation, not eliminated within 3 weeks or more. With old dislocations, the joint capsule thickens, becomes thicker, loses its elasticity. In the joint cavity proliferation of fibrous tissue, covering the articular surface and filling the free space.
Dislocation of the shoulder (dislocation in the shoulder joint) - persistent dissociation of the articular surfaces of the head of the humerus and articular cavity of the scapula as a result of physical violence or pathological process. When the congruence is broken, but the contact of the articulating surfaces is kept, it is said about the subluxation of the shoulder.
Dislocation of the clavicle accounts for 3-5% of all dislocations. There are dislocations of the acromial and sternal ends of the clavicle, and the former are found five times more often. It is very rare to find a dislocation of both ends of the collarbone at the same time.
Bleeding is the flow of blood from the vessel into the external environment, tissue or some cavity of the body. The presence of blood in a particular cavity has its name.
Wounds are open mechanical damages of soft tissues and internal organs (with penetrating wounds) with violation of their integrity, accompanied by gaping and bleeding.
Damage to the peripheral nerves of the limbs occurs in 20-30% of those injured in road accidents, in occupational injuries and during sports activities.
