Purpose:
The purpose of this study was to stratify fractures associated with child abuse in relation to the child's age.
Methods:
The Kids' Inpatient Database (1997-2012) was queried for all patients (<18 years old) with a diagnosis of fracture and child abuse. The primary outcome was age-related determinants of fracture distribution. Chi-squared analysis was used for statistical analysis where appropriate, with significance set at p < 0.05.
Results:
More than 39,000 children were admitted for child abuse, and 26% sustained fractures. Most were infants (median age 0 year [IQR 0-1]). 28% sustained multiple fractures, and 27% had skull fractures. By age, infants had the highest rate of multiple fractures (33% vs 16% 1-4 years), and the highest rate of closed skull fractures (33% vs 21% ages 1-4), while adolescents had more facial fractures (43% vs 11% ages 9-12), all p < 0.001. Multiple rib fractures were more commonly seen in infants (28% vs 8% ages 1-4), while children 5-8 years had the highest rates of clavicular fractures (7% vs 3% in infants), all p < 0.001.
Conclusion:
Age-related fracture patterns exist and may be due to changing mechanism of abuse as a child grows. These age-related fracture patterns can help aid in healthcare detection of child abuse in hopes to thwart further abuse.
Type Of Study:
Retrospective comparative study.
Level Of Evidence:
Level III.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
