Hip cold is the most common cause of hip disease in children between the ages of three and ten years old. At this age, it is the first cause to evoke in front of a child who begins to boast brutally.
It affects about 2 per 1, 000 children each child, more willingly boys than girls.
The causes of hip cold are not known. It is known that the symptoms are due to an inflammation of the synovial membrane, that is to say of the membrane that surrounds and protects the joint. This inflammation causes hypersecretion of the synovial fluid (the fluid surrounding the joint) and explains the effusion and pain characteristic of this pathology.
Bursitis or hygroma: kézaco?
You have probably already had bursitis, this inflammation of the serous bursas that protect our joints. Zoom on bursitis in the shoulder, knee or elbow
This disease is more common in certain seasons (winter and spring) and is usually secondary to an ENT infection (for example, otitis). As a result, a viral cause has been suspected. According to this theory, the virus is responsible for an inflammatory reaction at the level of the hip joint, the synovial membrane (we speak of synovitis), a slight effusion of the synovium ...
But just as likely as this cause may be, no virus has so far been highlighted by studies on the subject.
In the same way, no genetic cause has been found, nor even any predisposing genetic background.
