Diagnostic accuracy of flexion-extension radiography for the detection of ligamentous cervical spine injury following a normal cervical spine computed tomography

摘要

Background: Flexion-extension radiography (FER) has been utilised for the detection of ligamentous injury in patients who have been cleared of bony injury. Some studies call into question the diagnostic accuracy of FER, the high proportion of inadequate FER images and the adverse effects of prolonged cervical collar immobilisation although awaiting FER.
