Pelvic Fractures
Etiology of Pelvic Fractures
Most pelvic fractures result from high-energy injuries, most commonly caused by motor vehicle crashes (including motor vehicle–pedestrian collisions) or a fall from a height. Some (eg, symphyseal or pubic ramus fractures) result from minor or low-energy injuries (eg, falls at home), especially in patients with osteoporosis. Some pelvic fractures, typically in adolescents with open growth plates, are small avulsion fractures of the anterior or inferior iliac spine or of the ischial tuberosity. There are complex classification systems based on the mechanism, location, and/or stability of the injury
