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.
评估对重度颅脑损伤昏迷患者常规进行颅颈交界区计算机断层扫描（CT）的实用性。
在一项前瞻性研究中，对202例重度颅脑创伤患者（格拉斯哥昏迷量表评分为3 - 6分）进行头部和颅颈部CT检查。所有患者均进行了X线平片检查。然后对X线片和CT扫描结果进行盲法解读。
28例患者（13.9%）发生C1或C2骨折；其中11例患者的颈椎骨折在X线平片上未显示。9例患者（4.4%）发生枕髁骨折；其中8例患者的枕髁骨折在X线平片上未显示。
由于所有患者中有5.4%发生C1或C2骨折，4.0%发生X线平片未显示的枕髁骨折，因此对重度颅脑创伤患者常规加做颅颈交界区CT检查是有用的。
