Plunkett J. Fatal pediatric head injuries caused by short-distance falls . Am J Forens Med Pathol 2001;22:1-12.
Objective:
- To determine if there are witnessed and / or investigated fatal short distance falls that are concluded to be accidental.
Methods:
- Retrospective review of the US Consumer Product Safety Commission National Injury Information Clearinghouse data from Jan. 1, 1988, through June 30, 1999, for deaths resulting from the use of playground equipment.
- For all deaths, the author reviewed each original record from hospitals, emergency medical services, law enforcement and medical examiner offices (one autopsy was not available but it was discussed with the coroner).
Results:
More than 75,000 cases were reviewed:
18 deaths from head injury secondary to a fall associated with the use of playground equipment were recorded.
Age range of patients: 1-13 years
- five children: 12-24 months
- five children: 25-60 months
- eight children: 6-13 years
Cases:
Fall distance = “distance of closest body part from ground at beginning of fall”
- in 10 cases the distance reported is the actual distance
- in eight cases the distance was estimated
- 12 of the 18 cases were witnessed by a non-caretaker or videotaped
- six of the 18 children had an eye examination documented in the medical record, but none of the children had a “formal retinal evaluation.”

- In 13 of the 18 patients, there was evidence of a subdural hemorrhage
- In 13 of the 18 patients, there was evidence of cerebral edema
- In 10 of the 18 patients, there was evidence of a contact injury (skull fracture, subgaleal hemorrhage and / or contusion)
- six patients were reported to be immediately unconscious following the fall
- eight patients were reported to develop symptoms between five-30 minutes after the fall
- four patients were reported to develop symptoms between 3 hours and 2 days following the fall (three hours, six hours, 14.5 hours and two days)
Conclusions:
- In a review of more than 75,000 cases of injury resulting from falls associated with playground equipment in the United States over 11 years, 18 children aged 1-13 years suffered fatal head injuries.
- If the two children who had thrombocytopenia-absent radius syndrome or an arteriovenous malformation are removed, six children suffered fatal falls associated with a swing and 10 children suffered fatal falls from a horizontal surface, ladder or seesaw in this series.
