Most of the patients with rib fracture can be found by chest CT 3-dimensional reconstruction examination after chest trauma, but clinically there do exist a small number of patients with minor rib fracture, which can only be found when chest CT is reviewed again in 1 to 2 weeks. This is because for this part of the chest rib fracture patients, due to the rib fracture is relatively minor, just check the chest CT did not find obvious rib fracture, 1 ~ 2 weeks after the fracture end of the bone resorption, the fracture end is only visible, and then review the abdomen three-dimensional CT can be seen rib fracture. Therefore, for patients with a clear history of chest trauma and persistent pain in the chest, it is necessary to be alert to the possibility of rib fracture, and pay attention to the review of chest CT examination after 2 weeks to avoid missed diagnosis, and patients should go to the hospital in a timely manner if they usually have any discomfort, so as not to be careless, in order to avoid delaying the treatment.
