Rib fracture healed usually does not have sequelae, but some patients may have complications such as shock, pneumothorax, pulmonary atelectasis, and damage to internal organs. Usually, patients with rib fracture can be cured through conservative treatment or surgery without sequelae. As the broken end of rib fracture is relatively sharp, it may puncture the pleura, resulting in complications such as pneumothorax, hemothorax, and in some patients, pulmonary contusion. Chest pain may also cause increased respiratory secretions, weak coughing and shallow breathing, which may lead to complications such as atelectasis and pneumonia. Meanwhile, flail chest will lead to pressure imbalance between the two sides of the chest cavity, affecting blood circulation, and also cause hemorrhage and edema of the lung tissue, the patient will suffer from hypoxemia and respiratory distress within 24 hours, and in severe cases, shock may occur, or even life-threatening. In addition, rib fracture may also cause damage to the lungs, liver, spleen and other organs, as well as damage to the peripheral nerves. Although rib fracture has no obvious sequelae, patients need to strictly follow the doctor’s instructions for systematic treatment and good daily care to avoid complications.
