Pelvic fractures in pediatric patients are uncommon, accounting for no more than 0.2% of all fractures in this age-group. The pelvis in pediatric patients has different anatomical characteristics from adults; they have growth cartilages and a thick periosteum and the skeleton has greater elasticity. These particular conditions make possible to have avulsion injuries, and intrapelvic injuries without obvious involvement of the pelvic ring. The cause of pelvic fractures in pediatric patients is primarily related to traffic accidents, in which the minor travels as a pedestrian, and secondly as a passenger in a vehicle that suffers an accident. Therapeutic measures range from rest and protected walking with crutches in the case of avulsions, to the use of external fixation in unstable fractures of the pelvic ring. The medical team that receives these patients must have a clear vision of what does a pelvic fracture mean in a child, and knowing how to recognize those types of fractures that increase the suspicion of injuries associated, which can compromise the patient’s life more than the fracture itself.
