Rib cortical discontinuity is the imaging manifestation of a rib fracture, and whether or not it is important depends on the location of the fracture, whether or not the fracture is displaced, and the presence or absence of complications. X-rays usually show cortical discontinuity after a traumatic or other pathological injury to the body. When this occurs, a fracture is diagnosed. It is the main clinical criterion for the diagnosis of a fracture. If there is only a fracture with cortical discontinuity but no significant displacement, it can usually be treated conservatively with only braking, adequate rest after immobilization of the injury, and local symptomatic treatment. Patients can also take oral medications to invigorate blood circulation and promote fracture healing, and they can usually recover after 6-8 weeks of treatment. If the fracture is displaced and conservative treatment is ineffective and the situation is relatively severe, surgical treatment is required. Patients with rib cortical discontinuity usually need to avoid smoking and alcohol, avoid upper respiratory tract infections, and keep their bowels open to facilitate recovery.
