Outcomes of Pediatric Pelvic Fractures: A Level I Trauma Center's 20-Year Experience.

BACKGROUND

Pediatric pelvic fractures are rare. The contribution of pelvic fracture pattern, risk factors for associated injuries, and mortality are poorly defined in this population.

METHODS

Patients aged 0-17 with pelvic fractures at a level I trauma center over a 20-y period were reviewed. Fracture patterns were classified according to the Young-Burgess classification when applicable. Fractures were analyzed for location, pubic symphysis or sacroiliac widening, and contrast extravasation.

RESULTS

There were 163 pelvic fractures in 8758 admissions (incidence 2%). The most common associated injures were extremity fractures (60%, n = 98), abdominal solid organ (55%, n = 89), and chest (48%, n = 78), with the majority (61%, n = 99) sustaining injuries to multiple organs. Unstable fractures were associated with injures to the thorax (70% versus 40%), heart (15% versus 2%), and spleen (40% versus 18%), all P < 0.05. Nonpelvic operative interventions were required in 45% (n = 73) and were more common in unstable fractures (36% versus 19%), contrast extravasation (63% versus 26%), sacroiliac widening (36% versus 20%), and sacral fractures (39% versus 13%), all P < 0.05. Mortality was 13% and higher in males versus females (18% versus 5%), contrast extravasation (50% versus 3%), or sacroiliac/pubic symphysis widening (13% versus 2%) (all P < 0.05). Male gender (OR 6.03), brain injury (OR 6.18), spine injury (OR 5.06), and cardiac injury (OR 35.0) were independently associated with mortality (all P < 0.05).

CONCLUSIONS

Pediatric pelvic fractures are rare but critical injuries associated with significant morbidity and need for interventions. Increasing fracture severity corresponds to injuries to other body systems and increased mortality.
