Study DesignRetrospective medical record review.ObjectiveThe purpose of this study was to describe the incidence of other injuries that commonly occur in conjunction with cervical spine fractures and dislocations.Summary Of Background DataCervical spine fractures are often associated with other significant traumatic conditions, which may also require prompt diagnosis and management. However, the relative incidences of the injuries that occur in conjunction with various cervical spine fractures have not been well documented.MethodsThe radiographic reports of all patients who underwent CT scans of the cervical spine at a single level 1 trauma center over a 10-year period were reviewed. The medical records of individuals with acute, nonpenetrating fractures of the cervical spine were further assessed for any associated traumatic pathology including noncontiguous spine injuries and those affecting other organ systems (i.e., head and neck, intrathoracic, intra-abdominal/pelvic, and nonspinal orthopedic disorders).ResultsA total of 13,896 CT scans of the cervical spine were performed during this 10-year period of which 492 revealed acute fractures and/or dislocations. Of these subjects, 60% had sustained at least one additional injury. Overall, 57% were noted to have extraspinal injuries (34% head and neck, 17% intrathoracic, 10% intra-abdominal/pelvic, and 30% nonspinal orthopedic conditions) and noncontiguous spinal trauma was present in 19% of these cases (8% cervical injuries, 8% thoracic, and 6% lumbar). In general, the rates of associated injuries observed with occipital condyle and C7 fractures were significantly higher than those recorded for other cervical segments.ConclusionFor patients with a known history of cervical spine trauma, the frequencies of associated injuries were similar across all levels of the cervical spine with the exception of the injuries to the craniocervical junctions. In practice, this means that injuries to the cervical spine can likely be grouped together when considering other possible associated injuries. Further elucidation of these injury patterns will likely be useful for facilitating the expedient evaluation and proper management of these individuals.
