[0002] The most common chest injuries are single rib fractures, multiple rib fractures, and multiple rib fractures (flail chest). In clinical practice, multiple types of chest injuries often coexist, that is, complex chest injuries. Correct diagnosis and timely treatment are the key to the successful rescue of patients with chest injuries, which can effectively improve the survival rate and quality of life of patients. For example, rib fractures are more common in ribs 4-7. On-site first aid requires bandaging and fixing the chest wall to prevent the fracture ends from damaging the internal organs of the chest cavity.
