[Association relation of C0-C2 Cobb angle and cervical disc herniation].
Objective: Objective To investigate the relationship between cervical disc herniation and C0-C2 Cobb angle.
Methods: The clinical data of 301 patients with cervical disc herniation from 2020 to 2024 were retrospectively analyzed. The median value of C0-C2 Cobb angle measurements from 301 patients was used as the boundary, cervical disc herniation patients were divided into two groups, C0-C2 Cobb angle <28.50 group and 151 patients with C0-C2 Cobb angle≥28.50 group. Among them, 150 patients in C0-C2 Cobb angle <28.50 group included 53 males and 97 females, aged 23 to 76 (57.32±12.55) years, with a disease duration of 7 to 19 (13.81±5.32) months;the othor 151 patients with C0-C2 Cobb angle≥28.50 group including 61 males and 90 females, aged 25 to 74 (56.86±12.51) years, with a disease duration of 8 to 18 (14.13±5.56) months. The cervical lordosis angle (C0-C2 Cobb angle and C2-C7 Cobb angle), T1 inclination slope (T1S) and cervical sagittal axial distance (C2-C7 SVA) were measured on the lateral cervical radiographs. The correlation between C0-C2 Cobb angle and cervical disc herniation range, protrusion position, average protrusion size and other parameters was analyzed.
Results: When the C0-C2 Cobb angle<28.50°, the average protrusion size was (2.21±0.56) mm, the C2-C7 Cobb angle was (19.92±12.06)° and the C2-C7 SVA was (1.10±1.20) mm. When the C0-C2 Cobb angle≥28.50°, the average protrusion size was (2.38±0.60) mm, the C2-C7 Cobb angle was (12.01±13.09 )°, the C2-C7 SVA was (1.53±1.36) mm, and the difference was statistically significant (P<0.05). Between the two groups of patients with C0-C2 Cobb angle < 28.50° and C0-C2 Cobb angle≥28.50°, there were significant differences in the size of C3,4, C4,5, C5,6, C6,7, C7, T1 disc herniation in single segment (P<0.05 ). C0-C2 Cobb angle was correlated with age(r=-0.135, P<0.05 ), C2-C7 Cobb angle (r=-0.382, P<0.01 ), C2-C7 SVA (r=0.293, P<0.01), average protrusion size (r=0.139, P<0.05), and the size of C3,4 (r=0.215, P<0.01 ), C4,5 (r=0.176, P<0.01 ), C5,6 (r=0.144, P<0.05 ), C6,7 (r=0.158, P<0.05 ), C7T1 (r=0.535, P<0.05) disc herniation.
Conclusion: There is a positive correlation between C0-C2 Cobb angle and the size of cervical disc herniation. C0-C2 Cobb angle can reflect the degree of cervical disc herniation. Previous studies have shown that the biomechanical changes between C0-C2 Cobb angle, C2-C7 Cobb angle, C2-C7 SVA and cervical extensor muscle group may be risk factors for accelerating cervical disc herniation and this may be one of the mechanisms that C0-C2 Cobb angle is positively correlated with the size of cervical disc herniation.
