A blow to the rib cage can cause either a fracture or bruising to the membrane that covers the bone (periosteum). Both can be very painful, and it is very often hard to distinguish the difference, even with a X-ray.
A rib fracture is a break in one of the bones that compose the rib cage. Ribs may be fully broken or partially broken (cracked). When a rib is completely broken, the edges of the bones pose a danger of damaging or tearing internal organs, such as the lungs, liver or spleen, as well as blood vessels. Bone fractures, including fractures of the rib, are most commonly caused by trauma, such as fall or a motor vehicle accident.
