Epidural hemorrhage: is it abuse?

Area of Science:

• Pediatric Traumatology
• Neuroscience
• Forensic Medicine

Background:

• Childhood head injuries, including epidural hemorrhage (EDH) and subdural hemorrhage (SDH), can result from accidental trauma or abuse.
• Differentiating the etiology of intracranial hemorrhage is critical for appropriate medical and legal interventions.

Purpose of the Study:

• To compare the incidence of diagnosed abuse in children aged 3 years or younger presenting with EDH versus SDH.
• To investigate the biomechanical differences in injury mechanisms between EDH and SDH in pediatric patients.

Main Methods:

• Retrospective chart review of pediatric patients diagnosed with EDH or SDH between 1985 and 1991.
• Inclusion criteria: children 3 years old or younger admitted to a regional trauma center or children's hospital.
• Abuse diagnosis was determined through hospital records and Child Protective Services documentation.

Main Results:

• Abuse was diagnosed in 47% of children with SDH (28/59) compared to 6% of children with EDH (2/34).
• Children with SDH were more likely to have associated injuries (47% vs. 18% for EDH).
• No significant differences were observed in skull fractures, need for surgery, or mortality between EDH and SDH groups.

Conclusions:

• Epidural hemorrhages (EDH) are typically caused by linear impact forces, often from unintentional falls.
• Subdural hemorrhages (SDH) are more frequently associated with high-energy, rotational forces indicative of abuse.
• The findings support distinct biomechanical mechanisms for EDH and SDH, with SDH being a stronger indicator of inflicted injury.
