Diagrams depicting the paradoxical motion observed during respiration with a<unk>  segment The most common causes of<unk>  injuries are vehicle collisions, which account for 76% of<unk>  injuries. Another main cause of<unk>  injuries is falling. This mainly occurs in the elderly, who are more impacted by the falls as a result of their weak and<unk>  bones, unlike their younger counterparts who can fall without being impacted as severely. Falls account for 14% of<unk>  injuries.<unk>  typically occurs when three or more adjacent ribs are fractured in two or more places, allowing that segment of the thoracic wall to displace and move independently of the rest of the<unk>  wall.<unk>  can also occur when ribs are fractured proximally in conjunction with disarticulation of costal cartilages distally. For the condition to occur, generally there must be a significant force applied over a large surface of the thorax to create the multiple anterior and posterior rib fractures. Rollover and crushing injuries most commonly break ribs at only one point, whereas for<unk>  to occur a significant impact is required, breaking the ribs in two or more places. This can be caused by forceful accidents such as the aforementioned vehicle collisions or significant falls. In the elderly, it can be caused by deterioration of bone, although rare. In children, the majority of<unk>  injuries result from common blunt force traumas or metabolic bone diseases, including a group of genetic disorders known as osteogenesis imperfecta.
