Patients with broken ribs often experience pain, localized swelling, and difficulty breathing. 1. Pain and localized swelling: the localized chest wall of the injured patient will have swelling and obvious pain symptoms, and the pain is more intense when pressed. The localized pain will be aggravated to produce bone rubbing sound, and X-ray film can be taken to determine whether there is any fracture. 2. Difficulty in breathing: If the rib fracture injures the chest wall, there will be abnormal breathing movement, accompanied by subcutaneous emphysema, pneumothorax and hemothorax. If the abnormal respiration is very serious, the chest wall of the softened area will be invaginated during inhalation, and on the contrary, the softened area will bulge out to the outside during exhalation, which seriously affects the cardiopulmonary function of the patient. Clinically, the presence of rib fracture can be determined by taking X-ray films, which can show the fracture line and displacement of the broken end of the rib fracture, and can also determine the presence of pneumothorax and hemothorax.
