Study Design: Global cross-sectional survey. Objective: To develop an injury score for the AO Spine Subaxial Cervical Spine Injury Classification System. Methods: Respondents numerically graded each variable within the classification system for severity. Based on the results, and with input from the AO Spine Trauma Knowledge Forum, the Subaxial Cervical AO Spine Injury Score was developed. Results: An A0 injury was assigned an injury score of 0, A1 a score of 1, and A2 a score of 2. Given the significant increase in severity, A3 was given a score of 4. Based on equal severity assessment, A4 and B1 were both assigned a score of 5. B2 and B3 injuries were assigned a score of 6. Unstable C-type injuries were given a score of 7. Stable F1 injuries were assigned a score of 2, with a 2-point increase for F2 injuries. Likewise, F3 injuries received a score of 5, whereas more unstable F4 injuries a score of 7. Neurologic status severity rating scores increased stepwise, with scores of 0 for N0, 1 for N1, and 2 for N2. Consistent with the Thoracolumbar AO Spine Injury Score, N3 (incomplete) and N4 (complete) injuries were given a score of 4. Finally, case-specific modifiers M1 (PLC injury) received a score of 1, while M2 (critical disc herniation) and M3 (spine stiffening disease) received a score of 4. Conclusions: The Subaxial Cervical AO Spine Injury Score is an easy-to-use metric that can help develop a surgical algorithm to supplement the AO Spine Subaxial Cervical Spine Injury Classification System.

Degree Of Instability

Background. The main criteria for determining surgery strategy in patients with traumatic subaxial cervical injury are as follows: the type and degree of damage to the osteo-ligamentous structures of cervical spine that determines the level of instability; the value of spinal cord compression; the state of the sagittal profile. The aim of this study was to assess the degree of instability in different types of cervical spine injuries according to AOSpine Subaxial Cervical Spine Injury Classification System. Materials and methods. We performed a retrospective analysis of Х-ray, computed tomography and magnetic resonance imaging data of 168 patients with traumatic injury of subaxial cervical spine. All of them were hospitalized at the Department of Spinal Cord Pathology of the Romodanov Neurosurgery Institute of National Academy of Medical Sciences of Ukraine 2008–2018. We assessed the degree of instability using the Cervical Spine Injury Severity Score and determined the type of damage according to the AOSpine Subaxial Cervical Spine Injury Classification System. Results. We found that the median rate of instability increases progressively with increasing severity of injury type. The widest range of instability values is observed in the compression damage: from 6 points (95% confidence interval (CI): 4.76–6.84) in A1 type to 11 points (95% CI: 9.48–11.81) in A4. For A2 and A3 types, we registered 7 (95% CI: 6.68–7.53) and 8 points (95% CI: 7.97–9.01), respectively. A smaller range of values characterizes flexion-extension injuries. The median progressively increases from B1 type — 13 points (95% CI: 12.4–13.92) to B3 type — 15.5 points (95% CI: 14.5–16.35). The value for B2 is intermediate and is 15 points (95% CI: 13.59–15.52). We registered maximum values in flexion-extension injuries — 18 points, for both B2 and B3 types. C type has the highest level of instability — 17 points (95% CI: 16.58–17.86) and a quite wide range of estimated values: from 13 to 20 points. Conclusions. The general trend is an increase in the level of instability in the range from A1 to C injury subtypes, but even A1 type in some cases are quite unstable and require surgery. In contrast to the classical views, type A injuries are often accompanied by da-mage to the facet joints, which must also be taken into account when determining the individual treatment.
