Cortical distortion is a break in the integrity and continuity of the bone and is a type of fracture. Cortical distortion is a type of glaucomatous fracture, and glaucomatous fractures, which are most common in children, are similar to a young branch of a plant that breaks without breaking when exposed to violence. Children’s bones contain more organic material and the periosteum wrapped around the outside is relatively thick, so they are mechanically very elastic and resilient, and do not break or separate easily, which is called a glaucomatous fracture. If a green branch fracture occurs, it usually takes three months or even longer to fully recover, it should be supplemented with appropriate external fixation, go to the regular hospital in time to do the relevant examination, under the guidance of the doctor to carry out the corresponding treatment, pay attention to nutritional supplements, eat more vegetables.
