Infantile subdural haematoma and its relationship to whiplash injuries
Insights
Subdural hematoma in infants may result from shaking, not just direct head impact. This explains why it is common in abusive head trauma, even without external head injuries.
Area of Science:
- Pediatrics
- Neurology
- Forensic Medicine
Background:
- Subdural hematoma is a frequent finding in abusive head trauma.
- External head injuries are not always present in these cases.
Purpose of the Study:
- To explore the mechanism of subdural hematoma in battered child syndrome.
- To investigate the role of acceleration/deceleration forces in infant head injuries.
Main Methods:
- Analysis of clinical presentations of subdural hematoma in infants.
- Hypothesizing mechanisms based on injury patterns.
Main Results:
- Subdural hematoma can occur without direct head trauma, suggesting shaking as a cause.
- The hypothesis explains the high incidence and bilateral nature of subdural hematoma in battered children.
Conclusions:
- Infant shaking is a plausible cause of subdural hematoma in battered child syndrome.
- This mechanism accounts for the frequency and bilateral occurrence of subdural bleeds.
Abstract:
Subdural haematoma is one of the commonest features of the battered child syndrome, yet by no means all the patients so affected have external marks of injury on the head. This suggests that in some cases repeated acceleration/deceleration rather than direct violence is the cause of the haemorrhage, the infant having been shaken rather than struck by its parent. Such an hypothesis might also explain the remarkable frequency of the finding of subdural haemorrhage in battered children as compared with its incidence in head injuries of other origin, and the fact that it is so often bilateral.
