Dislocations of the wrist and its individual bones are quite rare. The most common dislocation is the lunate bone, and dislocations of the wrist distal to the first row of carpal bones are also recorded.
Subluxation of the radial head is most common in children aged 1 to 4 years. During this period, children often fall, and the adults accompanying them, trying to prevent the fall, pull the child by the straightened arm.
Forearm dislocations account for 18-27% of all dislocations. In the elbow joint, simultaneous dislocation of both bones is possible, as well as isolated dislocation of the radius and ulna. Depending on this, the following types of forearm dislocations are distinguished.
The frequency of habitual dislocation after traumatic can reach 60%. On average, it is 22.4%. Sometimes repeated dislocations occur without much force - it is enough to abduct and rotate the shoulder outward.
An old dislocation is a dislocation that has not been corrected for 3 weeks or more. In old dislocations, the joint capsule becomes denser, thicker, and loses elasticity. In the joint cavity, fibrous tissue growths appear, covering the articular surfaces and filling the free spaces.
Shoulder dislocation (dislocation in the shoulder joint) is a persistent separation of the articulating surfaces of the head of the humerus and the glenoid cavity of the scapula as a result of physical violence or a pathological process. When congruence is disrupted, but contact of the articulating surfaces is maintained, we speak of a subluxation of the shoulder.
Dislocation of the clavicle accounts for 3-5% of all dislocations. Dislocations of the acromial and sternal ends of the clavicle are distinguished, with the former occurring 5 times more often. Very rarely is a dislocation of both ends of the clavicle detected simultaneously.
Bleeding is the flow of blood from a vessel into the external environment, tissues or any cavity of the body. The presence of blood in a certain cavity has its own name.
Wounds are open mechanical damage to soft tissues and internal organs (in case of penetrating wounds) with a violation of their integrity, accompanied by gaping and bleeding.
