ABSTRACT
Objective:
To evaluate the profile of patients with fracture and / or dislocation of the subaxial cervical spine using the new AOSpine classification and to correlate it with the trauma mechanism and the type of neurological deficit.
Methods:
Analyses were performed of the medical records of patients admitted to a tertiary hospital with fracture and / or subaxial cervical dislocation during the period from 2009 to 2016. For the evaluation of the association between the two categorical variables, the Chi-square test was used with a significance level of p <0.05.
Results:
A total of 67 medical records were analyzed, in which a higher prevalence of type C fractures (49.3%) was observed. The neurological subclassification N4 (35.8%) was the most prevalent type found, followed by subtype N0 (26.9%). Among the main injury mechanisms found, the most prevalent was the motorcycle accident (29.9%). There was no statistically significant association between the injury mechanism and the AOSpine morphological classification (p> 0.05) or neurological deficit (p> 0.05).
Conclusion:
Cervical fractures of type C, due to automobile accidents were the most prevalent. It was not possible to determine an association between the degree of neurological involvement and the morphology of the injury. Level of Evidence II; Retrospective study.
