Whether a rib can heal on its own after a dislocation depends on the specific dislocation: 1, if the dislocation is mild, the fracture end can still be aligned, because there are intercostal muscles around, the fracture end of the rib is relatively stable, and it can heal initially in about 1 month, and heal on its own in 2-3 months, and gradually recover; 2, if the rib shows an oblique fracture, it is better to undergo surgery, because the fracture end of the rib forms an oblique fracture After the formation of oblique fracture, the tip of the fracture may affect the lung as well as the pleura and the chest cavity, so it is better to avoid the impact on the lung through surgery; 3. In case of rib dislocation combined with hemopneumothorax, the broken end of the fracture has injured the lung or the chest cavity, which affects the normal function of the lung, so it is necessary to adopt surgery as well as closed drainage of the chest cavity to suck out the blood and gas in the chest cavity through negative pressure, and to fix the fractured end through surgery. Otherwise, recovery is not possible and may lead to a life-threatening decrease in lung function.
