Cervical Spine Injury Assessment Techniques

Cervical spine injury following blunt trauma represents a critical concern in emergency and orthopaedic practice, with delayed diagnosis risking neurological impairment. Initial clearance relies on clinical decision rules, such as the NEXUS criteria or the Canadian C-spine rule, to identify low-risk cases for whom imaging may be safely deferred. Plain radiography was historically the first-line approach but has been largely supplanted by multidetector computed tomography (CT), which offers superior detection of bony injury and higher sensitivity for unstable fractures. Magnetic resonance imaging (MRI) serves as an adjunct to reveal soft-tissue, ligamentous and cord pathology not apparent on CT, informing surgical decision-making and collar removal timing. Dynamic radiographs, including flexion–extension views, may be employed selectively to assess stability once initial acute injuries have been excluded. Recent innovations encompass rapid high-pitch CT protocols for uncooperative patients, advanced MRI sequences to expedite scan time and reduced artefacts, and refining criteria for selective MRI utilisation in neurologically intact individuals. Interdisciplinary protocols now emphasise tailored imaging strategies that balance diagnostic yield, patient safety and resource allocation, reflecting global efforts to standardise cervical spine clearance across varied clinical settings.
