A fracture of the ribs can be cured if the fracture end punctures the lung. If the violence of the injury was so great that it directly pierced the lung, but the fracture was able to exit soon after the injury and did not remain in the lung, this situation can usually be treated conservatively if there is a small amount of hemopneumothorax without progressive aggravation, using antibiotics, hemostatic drugs and fixing the fracture end, and the lung can gradually heal. However, if there is a progressive aggravation of the hemopneumothorax in the lung or the fracture end remains directly in the lung wound, this condition can also be treated by opening the chest to reset the fracture and then repair the lung wound, which can also be treated.
