The principles of treatment for rib fractures are analgesia, clearing respiratory secretions, fixing the thorax, restoring chest wall function and preventing complications. 1.Treatment of single closed rib fracture Both ends of the fracture are supported by the upper and lower ribs and intercostal muscles, so dislocation and activity are rare and can be healed automatically. The main purpose of fixing the thorax is to reduce the activity of the fracture end and alleviate pain, and the methods are: wide adhesive tape fixation, multi-strip chest cloth fixation or elastic chest band fixation. The principles of treatment for simple rib fractures are pain relief, immobilization, and prevention of pulmonary infection. Pain relievers can be taken orally or injected intramuscularly if necessary. 2.Treatment of continuous shackle chest Correct paradoxical respiratory movements, anti-shock, prevention and control of infection and treatment of combined injuries. When the softening of the chest wall is small or located in the back, the paradoxical respiratory movement may not be obvious or serious, and local clamp pads can be used to apply pressure bandages. However, when the floating amplitude reaches more than 3 cm, it can cause serious respiratory and circulatory dysfunction, and when it exceeds 5 cm or when it is a bilateral continuous shackle chest soft chest syndrome, it can rapidly lead to death and must be treated urgently. 3. Treatment of open fractures Early and thorough debridement treatment should be performed. Remove broken bone fragments and lifeless tissues and bite flat the fracture break end to avoid puncturing the surrounding tissues. If there are intercostal vessels broken, the distal and proximal ends of the ruptured vessels should be sutured separately. Cutting a section of intercostal nerve is helpful to reduce postoperative pain. Pleural rupture should be treated as open pneumothorax. Postoperatively, tetanus antitoxin serum is routinely injected and antibiotics are given to prevent infection. Rib fractures can mostly heal on their own within 2-4 weeks, and the treatment does not emphasize the alignment of the broken ends as much as it does for fractures of the extremities.
