BackgroundInjuries to the cervical spine (CS) occur in 2% to 6.6% of blunt trauma patients. Studies have suggested that computed tomography (CT) alone is sufficient for CS clearance in unreliable patients based on follow-up magnetic resonance (MR) imaging not altering management. We hypothesized that an admission cervical spine CT with no acute injury-using new CT technology-is not sufficient for CS clearance in an unreliable patient.MethodsThe trauma registry was used to identify all patients with blunt trauma who had CS imaging with a CT and MR between August 2004 and December 2005. During this time period, a clinical guideline was in place whereby patients who had persistently unreliable examinations had MR despite a normal admission CT. Medical records were reviewed for demographics, Glasgow Coma Scale (GCS) score at time of MR, and injury specific data.ResultsSeven hundred thirty-four patients in total were identified. Two hundred three patients without obvious neurologic deficits but unreliable clinical examination, defined by a GCS score of ConclusionNewer generation CT continues to miss CS injuries in unreliable patients. MR changed the management in 7.9% of patients having had an admission CT with no acute injury. Thus, we recommend continued use of MR for CS clearance in the unreliable patient and ongoing evaluation as the quality of CT imaging continues to evolve.
