Abstract
Head injury is an important cause of mortality worldwide. The objective of the present study was to analyse the pattern of fatal head injury among patients seen in University College Hospital, Ibadan. The study was based on retrospective investigation of cases of fatal head injury referred by the coroner to the Department of Pathology, University College Hospital, between 1991 and 2000. Pertinent clinical and postmortem findings were extracted from available coroner's autopsy records.
There were 529 cases (402 males and 127 females). Their ages ranged from <1 year to 90 years (mean=33 years), the average age of females (27.8) being less than that of males (34.6) (p=0.00003). 83.8% were road traffic accidents, 8.9% falls from a height, 3.8% assault, and 3% gunshot injuries. 79.1% had a GCS of 8 or less at presentation. The mean survival period of children aged less than 15 years was 2 days while that of adolescents and adults aged 15 years and above was 5.6 days (p=0.02). Subdural (62.4%), subarachnoid (24.6%), epidural (10.2%), and intracerebral (10%) haemorrhages were the major causes of death. Skull fractures occurred in 38.2%, while cerebral contusions occurred in 22.1%. Intracranial infection was relatively uncommon in these patients. The present study has shown that young adults, predominantly males in their most productive years of life, are especially prone to fatal head injury.
