Epidemiology of Fractures in Children Younger Than 12 Months.

Objectives: The aim of this study is to determine the prevalence and characteristics of fractures in young infants attended at the pediatric emergency department (PED).

Methods: This is a retrospective study for 2 years (2011-2012) of children younger than 12 months attended with a fracture at the PED. Age, sex, site and type of fracture, mechanism of injury, time interval before seeking medical attention, and management were analyzed.

Results: One hundred one patients were included. They represented 0.3% (95% confidence interval, 0.2%-0.4%) of all children younger than 12 months attended at the PED. The median age was 7.7 months (interquartile range, 5.2-10.1 months); 58 (57.4%) were boys. The most common fracture was skull fracture (58, 57.4%), mostly parietal, followed by long bone fractures (27, 26.7%); transverse and torus fractures were the most common types, located at the diaphysis and distal metaphysis, respectively. The principal mechanism reported was falling (83, 82.2%) mainly from furniture. Fifty-one patients (50.1%) were attended in the first 6 hours after injury. Sixty-five patients (64.4%) were admitted at the hospital and the other 9 (8.9%) were controlled in outpatient visits. One of them was injured because of negligence and another was diagnosed with osteoporosis.

Conclusions: Fractures in young infants are uncommon at the PED, the skull fracture being the most common. Pediatricians should alert caretakers of the risks in normal development to prevent these injuries. Fractures caused by child abuse should always be discarded.
