Substantial head trauma: value of routine CT examination of the cervicocranium.

Abstract

To evaluate the usefulness of routine performance of computed tomography (CT) of the craniocervical junction in unconscious patients with substantial head injury. In a prospective study, CT of the head and the cervicocranium was performed in 202 patients with substantial cranial trauma (Glasgow Coma Scale scores of 3-6). Plain radiography was performed in all patients. Radiographs and CT scans were then blindly interpreted. Twenty-eight patients (13.9%) had C-1 or C-2 fractures; plain radiographs did not demonstrate cervical fractures in 11 of these patients. Nine patients (4.4%) had fractures of the occipital condyles; plain radiographs did not demonstrate occipital condyle fractures in eight of these patients. Because 5.4% of all patients had fractures of either C-1 or C-2 and 4.0% had occipital condyle fractures not seen at plain radiography, routine additional performance of CT of the craniocervical junction is useful in patients with substantial cranial trauma.
