PURPOSE: To verify the clinical applicability of a modified classification system in distractive-extension cervical @entity130 that reflects the degrees of soft tissue damage and @entity1566 while complementing previous Allen classification and subaxial cervical @entity130 classification (SLIC) system. METHODS: A total of 195 @entity1 with cervical spine distraction-extension (DE) injury were retrospectively classified. We added stages IIIA (with concomitant @entity1566 without @entity854 ) and IIIB (with concomitant additional soft tissue swelling) to the existing stages I and II of the Allen classification. We also supplemented the SLIC system by refining and assigning scores to bony morphology and soft tissue damage. The previous and proposed classification systems were compared by analyzing their scoring performances in terms of clinical features and prognosis. RESULTS: The Allen classification yielded 153 and 42 @entity1 with stage 1 and 42 stage 2 injuries, respectively. @entity1 classified according to the proposed system were stratified as follows: stage I, 58; stage II, 27; stage IIIA, 33; and stage IIIB, 77. Regarding @entity16 and prognosis, stages IIIA and IIIB were poorer than stage I but significantly better than stage II (P  <  0.05). On the SLIC system, 146 @entity1 scored >= 5; and 37 and 12 @entity1 scored 4 and  <=3 points, respectively, whereas the numbers of @entity1 who scored >= 5, 4, and  <=3 points on the modified SLIC system were 170, 21, and 4, respectively. CONCLUSIONS: The proposed classification and scoring system to complement the Allen classification and SLIC system with respect to the degrees of soft tissue damage and @entity1566 is considered effective for diagnosing and determining therapeutic directions and prognosis in cases of cervical spine extension injury.
