These are unstable injuries and have a high association with intra-abdominal injuries. There is a high incidence of associated intra-abdominal injuries (especially the pancreas, duodenum, and abdominal aorta) that can result in increased morbidity and mortality. Associated intra-abdominal injuries appear to be more common in the pediatric age group with an incidence approaching 50%. • Chance fracture is also known as the seatbelt fracture . The fracture typically occurs where the fulcrum is the seatbelt and the point of motion is the spine itself. Therefore, the spine tears apart in a horizontal fracture into the upper and lower parts. Thus, the anterior and middle columns fail in compression (moving together or in flexion ), and the posterior column fails in distraction (moving apart). Bones often fracture before the ligaments because the ligaments have higher tensile strength than the bones
