It is to be feared after a shock, if your child suffers a lot and can no longer use one of its members.
The bones of children often break into "green wood", like a branch, without moving, because they are flexible and can bend without breaking. Only an X-ray can determine the exact severity of the fracture.
If it is open, that is to say, accompanied by an injury, cover it with a sterile compress and take your child to the emergency department. Avoid drinking or drinking, anesthesia may be necessary to reduce the fracture.
