Patterns of fractures in accidental and non-accidental injury in children: a comparative study
Insights
Child abuse fractures in young children often present as multiple injuries, including rib fractures and spiral long bone fractures. These patterns, especially without significant trauma, strongly indicate child abuse, particularly in infants.
Area of Science:
- Pediatrics
- Orthopedic Surgery
- Child Abuse Research
Background:
- Distinguishing fractures due to child abuse from accidental injuries is critical for child protection.
- Previous studies have highlighted specific fracture patterns associated with non-accidental trauma.
Purpose of the Study:
- To compare fracture incidence and patterns in abused children versus a control group.
- To identify specific fracture characteristics indicative of child abuse.
Main Methods:
- Retrospective case-control study comparing fracture patterns in abused children (n=35) with non-abused children (n=826).
- Data collected from 1976-1982 for abused cases and Jan-June 1981 for controls.
- Analysis focused on age, fracture multiplicity, location, and type.
Main Results:
- Abused children (all under 5) were significantly more likely to have multiple fractures and head/neck bruising (p<0.001).
- Rib fractures without major chest trauma and spiral/oblique long bone fractures (gripping/twisting injuries) were highly suggestive of abuse.
- Spiral humeral shaft fractures were significantly more common in abused children (p<0.001).
Conclusions:
- Specific fracture patterns, including multiple fractures, rib fractures, and certain long bone injuries, are strong indicators of child abuse.
- A significant proportion of fractures in children under 18 months may be linked to abuse, necessitating careful evaluation.
Abstract:
The incidence and pattern of fractures in children who had been abused were compared with those of fractures sustained by children of similar ages in whom abuse had been excluded. From 1976 to 1982 there were 35 children with fractures resulting from child abuse, and all were aged under 5. Of the 826 children in the control group, seen from January to June 1981, 85% were aged over 5. Abused children were much more likely to have multiple fractures (p less than 0.001) and bruising of the head and neck (p less than 0.001). Fractures of the ribs were common in children who had been abused, and their presence, in the absence of major chest trauma, strongly suggested that abuse was occurring. Injuries to the long bones were invariably spiral or oblique fractures or subperiosteal new bone formation--both "gripping or twisting" injuries. Spiral fracture of the humeral shaft was significantly more common (p less than 0.001) in the group of abused children. Classic metaphyseal chip fractures were uncommon. One child in eight aged under 18 months who sustains a fracture may be a victim of child abuse.
