Identifying non-accidental fractures in children aged <2 years

Purpose: Fractures are the second most common presentation of child abuse following soft-tissue bruising and burns. It is often difficult to determine potential abuse in a child presenting with a non-rib fracture(s) and without soft-tissue injuries. Methods: One hundred and fifteen consecutive patients aged ≤2 years who presented with a fracture between January 2010 and June 2012 to our emergency department (ED) or pediatric fracture clinic were retrospectively analyzed. Statistical analyses were carried out for non-accidental fractures based on age (<1 year vs 1–2 years), location of presentation (ED vs pediatric fracture clinic), type of long bone fracture, number of fractures, and patient demographics. Results: Fractures in 19 of 115 (17 %) patients were reported as non-accidental trauma (NAT). Eighty (70 %) of the 115 patients first reported to the ED. Thirty-two percent of fractures in children aged <1 year and 5 % of fractures in children aged 1–2 years were reported as NAT (p < 0.001). Sixteen of 19 (84 %) patients reported for abuse had multiple fractures; 15 of these patients were aged <1 year. Eight of 11 (73 %) reported femoral fractures were transverse fractures. Corner fractures (12) only occurred in children aged <1 year and never occurred in isolation; all of them were reported as NAT. Four of 60 patients (7 %) with commercial insurance and 15 of 55 patients (28 %) with Medicaid were reported as NAT. Conclusions: Age less than 1 year, multiple fractures, corner fractures, transverse fractures, and covered by Medicaid were the most common factors associated with reporting of NAT.
