ABSTRACT

Objective:

We aimed to compare the cervical sagittal parameter measurements of normal healthy population with cervical degenerative diseases in the Turkish population.

Material and Methods:

These four parameters were analyzed in standing lateral graphies of 40 (10 male, 30 female) patients in 50-75 age groups (mean age: 63,69 ± 12) and 30 (6 male, 24 female) healthy individuals in 20-40 age groups (mean age: 29,51 ± 9,27). C0 inclination angle (angle made with the horizontal line of the Frankfurt line), C0-C2 angle (angle between the Mc Gregor line passing through the skull base and C2 lower end plane), T1 slope angle (angle between C7 lower end plate and T1 upper end plate), and cervical lordosis (angle between C2-C7) were assessed. We compared the angle measurements in the two groups.

Results:

Cervical sagittal parameters; C0 inclination angle (28,5°± 9,2°), C0-C2 angle (44,8°± 9,2°), T1 slope angle (3,9° ± 1,9°) and cervical lordosis (17,5°± 2,2°) were measured in patients with cervical degenerative disease. C0 inclination angle (24,8° ± °2,8), C0-C2 angle (43,0°± 14,8°), T1 slope angle (2,7° ± 1,3°) and cervical lordosis (42,4°± 7,6°) were measured in normal individuals. Cervical sagittal parameter measurements were compared between normal healthy individuals and patients with degenerative disease. C0 inclination angle and C0-C2 angle were similar, but T1 slope was higher while cervical lordosis angle was lower with the statistically importance (p < 0,05).

Discussion:

As a result, in the degenerative disc disease of the subaxial region, any changes of the C0 inclination and C0-C2 angles was not find, but T1 slop and cervical lordosis angles was disturbed. Especially, at the level of degenerative disc disease, lordosis pattern changed to kyphotic pattern was determined. Due to this situation make decrease the global cervical lordosis. In the light of our data’s, we concluded that degenerative disc disease effect sagital plane parameters of the subaxial region in the patients with Cervical Degenerative Disc Disease (CDDD).
