COMPARAçãO DOS PARâMETROS SAGITAIS NOS DIFERENTES TIPOS MORFOLóGICOS DA CURVATURA CERVICAL

COMPARACIóN DE LOS PARáMETROS SAGITALES EN LOS DIFERENTES TIPOS MORFOLóGICOS DE LA CURVATURA CERVICAL

ABSTRACT

Objective:  Evaluate and compare sagittal parameters of the spine in different morphological types of cervical curves.

Method:  ten lateral radiographs of the cervical spine of each morphological type of cervical curvature (lordotic, straightened, sigmoid and kyphotic) were used to measure the C1-C2 angle, C2-C7 angle using the Cobb method, T1 inclination, T1-lordosis inclination C2-C7 cervical and axial sagittal cervical axis. Parameter measurements were compared in the different morphological types of cervical spine curvature.

Results:  a statistical difference was observed in the C2-C7 angle, T1 inclination and T1 inclination-C2-C7 cervical lordosis in the different morphological types of cervical curvature. No statistical difference was observed in the C1-C2 angle and axial sagittal cervical axis in the different morphological types of cervical curvature.Conclusion: sagittal parameters (C2-C7 angle by Cobb method, T1 inclination, T1 inclination-C2-C7 cervical lordosis) present differences in the different morphological types of cervical curvatures and must be considered in the evaluation and therapeutic development. Evidence level III, retrospective comparative study.
