Objective To investigate the correlation between cervical sagittal balance parameters and cervical disc de-generation degree.Methods The degeneration degree of C2～7 intervertebral disc and the parameters of sagittal bal-ance of C2～7 Cobb angle,C0～7 Cobb angle,vertical distance of C2～7 sagittal plane(C2～7 SVA),T,slope(T1S)and the value of T,S-C2～7 Cobb angle were measured on the lateral radiographs of 150 patients with cervical spondylosis.The correlation between the cervical disc degeneration degree and gender,age and cervical sagittal plane parameters was analyzed.According to the C2～7 cervical disc degeneration degree,they were divided into group A(mild degree of degeneration,total scores＜3 points,56 cases)and group B(severe degree of degeneration,total scores ≥3 points,94 cases).The difference of sagittal plane parameters between the two groups and the correlation between parameters in the two groups were compared.Results There were statistical differences in the total scores of C2～7 cervical disc de-generation among different ages(P＜0.01),but there were no statistical differences in gender and cervical curvature(P＞0.05).T1S:it was positively correlated with the total scores of C2～7 cervical disc degeneration(P＜0.05),which was not correlated with the other sagittal plane parameters(P＞0.05).T1S of group B was higher than group A(P＜0.05);there were no statistical differences in other sagittal plane parameters between the two groups(P＞0.05).In the two groups,C2～7 Cobb angles were positively correlated with T,S(P＜0.01),and negatively correlated with T1S-C2～7 Cobb angles(P＜0.01).C2～7 SVA was positively correlated with T1S-C2～7 Cobb angles(P＜0.01);there was negative correlation between C2～7 Cobb angle and C2～7 SVA in group A(P＜0.01),but no correla-tion between them in group B(P＞0.05).There was positive correlation between T1 S and C2～7 SVA in group B(P＜0.01),but no correlation between T1S and C2～7 SVA in group A(P＞0.05).There was no correlation between T1S and T1S-C2～7 Cobb angle in two groups(P＞0.05).Conclusions The cervical disc degeneration degree is closely related to age.Among the commonly used cervical sagittal plane parameters,T1S is positively correlated with overall cervical disc degeneration,and in patients with severe cervical disc degeneration,T1S is positively correlated with C2～7 SVA.
