BackgroundTraumatic craniocervical dissociation (CCD), which includes atlanto-occipital dissociation and vertical distraction between C1-C2, is often an immediately fatal injury that has increasingly been associated with survival to the hospital. Our aim was to identify survivors of CCD based on clinical presentation.MethodsWe retrospectively reviewed the Harborview Medical Center Trauma Registry and the King County Medical Examiners database from 2001 to 2006. Patients>or=12 y old were identified by ICD-9 code, radiographic diagnosis on lateral cervical spine films, and CT. We examined age, gender, mechanism of injury, presentation and prehospital and hospital interventions, and radiographic findings to distinguish survivors and non-survivors.ResultsOf 69 patients with CCD, 47 were diagnosed post mortem, 22 were diagnosed in hospital, and seven survived to discharge. When comparing survivors and non-survivors, age, gender, and injury severity score were not significant. Survivors had significantly higher GCS, and were more likely to be normotensive; none had cervical cord injury; 80% of non-survivors had a basion-dental interval (BDI) of >or=16mm.ConclusionsTrauma patients diagnosed with CCD in the ED, with cervical cord injury, requiring CPR, and with GCS of 3 will not survive their injury. Wider BDI is associated with mortality.Copyright 2010 Elsevier Inc. All rights reserved.
