If the fracture of the saber is not very displaced or is only a crack fracture, conservative treatment is the main treatment. The whole thorax can be fixed with the chest belt, so that the saber is also relatively fixed, thus making it grow in a stable environment. In addition, during the fixation period, it is also possible to take more drugs for long bones or to apply herbs or traditional Chinese medicines that activate blood circulation, reduce swelling and pain to assist in the treatment. It is important to note that the fracture of the fenestra may cause damage to the stomach or the thorax, so it is necessary to improve the relevant upper abdominal and thoracic examination, and if there is a hemopneumothorax or a rupture or injury of the stomach, it is necessary to do the corresponding treatment.
