OBJECTIVE: Retrospectively assess the factors related to cervical trauma, according to the type of fracture based on the AO classification, taking into account etiological and epidemiological aspects of the event. METHODS: Records of patients with cervical fractures were retrospectively reviewed, from 2004 to 2009. The sub-axial fractures (C3-C7) were studied because they fit into only one classification (AO). Frontal and lateral x-rays were used as well as CTs to divide the fractures into A (compression), B (distraction) and C (rotation), in accordance with the presented pattern. The following parameters were assessed: gender, age, AO classification, trauma mechanism, presence of neurological deficit, and conservative or surgical treatment. RESULTS: The study included 264 records from the spine, where 216 patients were male and 48 female. The average age of these patients was 38.55 years. The most common mechanism of injury of the cervical sub-axial fractures was car accident with 84 cases. Regarding the type of fracture by the AO classification, the most frequent was type B. Out of the assessed cases, 136 patients presented complete or partial neurological deficit. The surgical treatment was performed in 166 cases. CONCLUSION: It is clear, based on the data presented, that cervical fractures are a major problem to the public and private health in Brazil. The prevention of the cervical fractures presents the most cost-effective approach to these injuries.
