All surgeries have risks, just a difference in the magnitude of the risk. Rib fractures are generally less risky to operate on, unless the patient is elderly, generally in poor physical condition, has a combination of heart disease, or has a combination of ruptured internal organs, bleeding, hemopneumothorax, etc., in which case the risk of surgery is further increased. As with all surgeries, if the patients themselves are in poor physical condition, with underlying diseases such as cerebral infarction, heart attack, liver or kidney insufficiency, the risk of surgery will increase accordingly. However, for people who are generally in good health, the risk of surgery is very low if they simply have a rib fracture.
