Search strategy exercise - a clue• A 70-year-old gentleman presents to the Emergency Department

(ED) after sustaining a fall from a standing position. He had no loss of consciousness and was brought to the ED with his c-spine immobilised.

• He was log rolled and had tenderness over the C5, C6 and C7 cervical vertebrae. As per the ED protocol the patient had plain radiographs of his cervical spine to rule out any bony injury.

• The plain films showed no evidence of any fractures, but as the patient was clinically tender over the cervical spine he was kept in our ED observation ward overnight with his cervical spine immobilised for a CT scan in the morning. The following morning he had a CT scan which showed fractures of C5 and C6 vertebrae.

The answer

• Population: Geriatric population (> 65 years of age) who have suffered blunt trauma to the neck

• Intervention: Computed Tomography• Comparison: Plain radiographs• Outcome: Improve detection of cervical

fractures in geriatric population
