A sternal fracture is a disruption of the integrity or cortical continuity of the sternum, which is caused by the direct action of violence on the sternum or the disruption of the continuity of the bone due to compression of the sternum. Sternal fracture is mainly caused by external force acting on the sternal region, and the fracture occurs in the sternal body area where the sternal body and sternal stem are connected. The main manifestations are pain, swelling of the sternum, change of position, change of shape, etc. The diagnosis of sternal fracture is based on the history of external impact, examination of the chest with pressure pain, if the fracture is displaced, local shape changes, combined with chest X-ray, chest CT and other examinations to clarify the diagnosis. For the treatment of sternal fracture, bed rest and pain relief are required for the treatment of simple sternal fracture without dislocation. After the dislocation is stabilized, fracture repositioning and surgical fixation will be performed. In case of complications, such as pneumonia, atelectasis, pulmonary insufficiency, pleural effusion, pneumothorax, etc., treatment is required. In conclusion, if you have a sternal fracture, you need to seek medical attention as soon as possible, and you should follow the corresponding treatment such as repositioning, fixation, surgery and medication. Pay attention to bed rest, eat appropriate food containing more calcium, do not do strenuous exercise, do not eat spicy food, do not drink alcohol.
