Objective:
To study the patterns and morphologic characteristics of blunt head injury and analyse its formative mechanism in attempt to provide references for medicolegal expertise.
Methods:
The statistical analysis was done in terms of gender, age, as well as the nature, pattern, location, and feature of the injuries.
Results:
Among the 202 cases of head injury-induced death, 124 were male and 78 female with the age ranging from 1-81 years. Death caused by homicide was dominant (106, 52.5%), followed by suicide (49, 24.3%) and accident (44, 21.8%). The majority of suicide-induced death were by falling from height, and traffic crash was responsible for majority of unexpected death cases. The morphology and pathogenesis of the injuries varied according to differences on the mode, magnitude, and orientation of the outside force giving rise to blunt injury as well as the character of vulnerants.
Conclusion:
Studies on the morphology and its formative rationale of blunt head injury will offer easy access to medicolegal expertise on the mode and character of the injury.
