Symptoms of rib fractures include, firstly, there is usually a clear history of trauma, either from direct impact or from falling and the ribs making contact with the ground, etc.

Secondly, the main symptoms of a rib fracture include three points:

The first is local deformity. If it is a single rib fracture, this deformity is generally not easy to detect. However, after multiple rib fractures, this deformity becomes readily apparent, and you can see that the chest cage is abnormal, with a caved-in appearance. Moreover, in cases like flail chest, breathing is also abnormal. Normally, when inhaling, the ribs should expand outward, but if flail chest occurs, the chest cage appears to expand inward during inhalation; therefore, such a condition often requires surgical treatment, otherwise the consequences are very serious.

The second symptom is friction sound and bone rubbing sensation. Some people, after fracturing a rib, during deep breathing or activity, hear cracking sounds from within. This occurs because the continuity and integrity are disrupted by the fracture, and then during breathing or during movement, there is friction between the bones.

The third point is abnormal movement, which occurs at locations without joints, resembling joint movements. Normally, a person has 12 ribs on each side. If the continuity and integrity of the ribs are not damaged, there should be no abnormal movement; that is, pressing on the ribs should not cause sensations similar to joint movements at places where there are no joints.

Therefore, the symptoms of a rib fracture include three points: the first point being local deformity; the second, bone friction sounds and sensations; and the third, abnormal movement. If any of these three symptoms are present, it is generally indicative of a rib fracture.
