Acetabular fracture in a 16-year-old secondary to an all-terrain vehicle accident

All-terrain vehicles have been associated with a large number of injuries in the pediatric age group. Despite strict regulations governing the sale and manufacture of these vehicles, they continue to be in widespread use. We report a case of a 16-year-old boy with an acetabular fracture secondary to being thrown from an all-terrain vehicle. Acetabular fractures are rare in the pediatric population and are most commonly associated with motor vehicle accidents and other high-energy trauma. Although the diagnosis is straightforward, delayed presentation is not uncommon.
