Fractures of the rib cage in the chest usually have a history of antecedent trauma, violent impact resulting in rib fracture, or more severe osteoporosis in the elderly, so the medical history is considered first. Secondly, rib fractures produce chest pain, breathing pain, coughing, coughing up sputum, blood in the sputum, squeezing pain when pressing on the thorax, and in some severe cases, collapse of the chest wall. Finally, some patients may develop bone rubbing sounds. If this cannot be identified, it may be due to a very mild fracture, just a crack without fracture, which is also a very mild symptom. If the fracture is not identified, it is best to perform imaging tests, such as X-rays or CT, so that it can be clearly identified.
