Increased lung texture in rib fracture may be due to direct violence or indirect violence trauma triggered by lung inflammation. 1. Direct violence: direct violence is often seen in the chest by the impact of injuries, punches and clubs, resulting in fractures, which leads to damage to the chest organs, lung tissue contusion and inflammation, there will be an increase in the lung texture and other phenomena, and in severe cases, there may be tightness in the chest, dyspnea and other manifestations. 2. Indirect violence: rib fracture caused by indirect violence occurs in parts other than the point of action of violence, and the fracture end of the rib is displaced outward, which can easily cause damage to the soft tissues of the chest wall, thus triggering a hematoma in the chest, and the lungs are squeezed to produce inflammation, and the phenomenon of increased lung texture can be seen in the imaging examination. Rib fracture lung texture increase, it is recommended that patients seek timely medical treatment, so as to avoid delaying the condition.
