Background: There is an argument for the benefit of the helmet wearing at the time on a bicycle ride. We discuss the usefulness for head injury in traffic accident.
Methods: We reviewed 13 cases, admitted to PICU in our hospital from April 2011 to April 2015, by traffic accident on a bicycle ride. We compared sex, age, conscious level and imaging findings between the cases with (A group) and without bicycle helmet (B group).
Results: There was no significant difference in two groups about sex, age, and conscious level. However, more cases exist in B group as for skull fracture, brain contusion, and subcutaneous hematoma. On the other hand, A group had more cases suffered from the diffuse axon injury and subarachnoid hemorrhage.
Conclusion: Helmet is effective to the direct injury of head, but might be little effective to the rotational injury.
