Ribs are indeed prone to fracture in case of chest injury. The bony thoracic support of the ribs in the chest protects the internal thoracic organs involved in respiratory functions, and because of the negative pressure in the thorax, and because the ribs are long and thin and not fully supported medially, they are prone to fracture when subjected to trauma, especially in the elderly when osteoporosis is evident. Rib fractures often occur in the 4th-7th ribs, mainly because the ribs in this segment are long and thin, and they are in the middle of the thorax, so when the chest is subjected to violence, all the force is blocked by the ribs, plus there is no obvious support in the thoracic cavity, and the ribs themselves are long and thin and circular in structure, so they are more likely to fracture. Rib fractures are more common in clinical practice, especially in many elderly people with significant osteoporosis, and a rib fracture may occur with a sneeze, which can be clearly diagnosed by 3D CT reconstruction.
