BackgroundThe influence of trauma-related kinematics on the injury pattern of the cervical spine is currently not considered in the available classification systems, only the force vector. Whether the strength of the trauma has an additional influence on the number and complexity of the injuries and whether this can be classified, has not yet been finally investigated.ObjectiveWhat influence do different kinematics apart from the traumatic force vector have on injuries of the cervical spine?Material And MethodsBased on the AOSpine classification system for the upper and subaxial cervical spine, data from 134 trauma patients from a first level trauma center were retrospectively analyzed. Analogue to the S3 guidelines on polytrauma, patients were assigned to six trauma groups and the injuries were classified on the basis of computed tomography (CT) cross-sectional imaging.ResultsA higher trauma energy had a significant impact on the number of cervical spine injuries (p = 0.005). In low velocity accidents C2 was the most frequently injured vertebra (51%; p = 0.022) and high velocity accidents showed more C7 fractures (37%; p = 0.017). Furthermore, upper cervical spine injuries occurred more often in low energy trauma and older female patients (e.g. falling from a standing position). Subaxial cervical spine involvement was found significantly more often in high velocity accidents and younger male patients (p = 0.012).ConclusionExact knowledge of the trauma mechanism is helpful in the primary treatment of an injured person. Injury patterns can be better estimated and the appropriate diagnostics can be initiated. The results underline the importance of immediate cervical spine immobilization even after minor trauma. In high velocity trauma, patients more often suffer from lower cervical spine injuries, especially C7. Due to the accumulation of multilevel spinal injuries in high velocity trauma, radiographic imaging of the whole spine is advisable.
