ABSTRACT BACKGROUND: Head injuries constitute one of the leading causes of pediatric morbidity and mortality. Most injuries result from accidents involving an acceleration/deceleration mechanism. However, a special type of head injury occurs when the children sustain a traumatism whose main component is a static load in relation to a crushing mechanism with the head relatively immobile. PATIENTS AND METHODS: We report a series of children who sustained a craniocerebral injury of variable severity produced by head crushing. We also analyze epidemiological and clinical data, and biomechanics in these injuries. RESULTS: Mean age of the group (13 boys/6 girls) was 4.1 years. All patients showed external lesions (scalp wounds or hemorrhage from the nose, ears, or throat). Eleven children were initially unconscious. Six children presented cranial nerve deficits in addition to impaired hearing. Skull base fractures were seen in most cases with extension to the vault in 11 instances. Fourteen patients had an associated intracranial lesion, including two with diffuse axonal injury. Surgery was performed in three instances. Only seven patients were left with sequelae. DISCUSSION AND CONCLUSIONS: The observed skull, brain, and cranial nerve lesions corresponded to a mechanism of bilateral compression of the children's heads mainly occasioned by a static load, although an associated component of dynamic forces was also involved. The skull and its covering and the cranial nerves were the most severely affected structures while the brain seemed to be relatively well preserved. Most crush injuries appear to be preventable by the appropriate supervision of the children.
