Dislocation
Dislocation (luxatio) - persistent displacement of the articular ends of the connecting bones beyond the boundaries of their physiological mobility, leading to dysfunction of the joint.
Allocate dislocation:
- Central femur (femoris centralis) - dislocation of the hip in combination with a fracture of the bottom of the acetabulum, in which the head of the femur is displaced into the pelvic cavity;
- Congenital (congenita) - caused by the intrauterine abnormal development of the elements of the joint (mainly the hip);
- Old (inveterata) - which remained unreduced after injury and does not lend itself to closed reduction due to changes that have occurred in the tissues adjacent to the joint;
- Incomplete (synonym: subluxation) - in which the contact of the articular surfaces is partially preserved;
- Paralytic (paralytica) - pathological dislocation caused by paralysis of one of the limb muscle groups, leading to an overweight of the antagonist muscle group;
- Pathological (pathologica) - caused by a disease of the joint, which causes violations of the articular surfaces (ends) of the bones;
- Complete (completa) - in which there is a complete divergence of the articular surfaces;
- Habitual (habitualis) - dislocation, systematically repeated in the same joint, caused by anatomical changes in the articular ends (surfaces) of the bones and / or weakness of the ligamentous apparatus of the joint and adjacent muscles;
- Traumatic (traumatica) - caused by external mechanical stress.

First Aid For Dislocation - Symptoms, Actions
Dislocation is a stable displacement of the articular ends of the bones, as a result of which the joint ceases to perform its function
Automatism - Dictionary Of Medical Terms
Automatism (Greek automates spontaneous, self-acting) - the ability of individual cells, tissues or organs to rhythmic activity in the absence of obvious connections with external stimuli
Dislocation - Symptoms, First Aid, Causes, Types
Dislocations are a mutual displacement of the articular ends of the bones articulating with each other. For first aid, it is necessary to fix the limb in the position that it took after the injury
Clavicle - Fracture, Dislocation, Displacement
The clavicle is a paired tubal bone located above the first rib and connecting a person's hands to the body
Patella - Structure, Function, Ligaments, Displacement, Dislocation, Fracture
The patella is a large human sesamoid bone located in the thickness of the quadriceps of the thigh. Takes part in the work of the knee joint
