No shinkei geka. Neurological surgery

We reviewed the records of 1,335 minor head injury patients with initial Glasgow Coma Scale (GCS) scores of 15 treated by our neurosurgery service between January 1998 and December 2000. Skull X-ray was performed in 945 patients (71%), and Computed tomography (CT) was performed in 590 patients (44%). Skull fracture was shown radiographically in 24 patients (2.5%), and abnormalities on the initial CT were seen in 29 patients (4.9%). ⋯ Patients required neurosurgical intervention in 4 cases, and all of those were acute epidural hematoma with skull fracture. In this study, the first thing we should do for asymptomatic minor head injury patients with a GCS score of 15 is to investigate the presence of a skull fracture by skull X-ray. Head trauma patients with a skull fracture and post-traumatic vomiting should undergo CT to facilitate detection of intracranial lesions, even when there are no abnormal neurological signs.
