All patients were diagnosed with CSM by nuclear magnetic imaging and other imaging methods. C2\u2013C7 Cobb angle and T1 slop (T1S) were measured on the sagittal, T2\u2010weighted magnetic resonance image of cervical spine, and C7\u2013T1 intervertebral foramen area were measured using oblique cervical spine X\u2010rays. Patients were divided into two groups according to the value of C2\u2013C7 Cobb angle, including lordosis group (C2\u2013C7 Cobb angle &gt;10\u00b0, <jats:italic>n<\/jats:italic>\u00a0=\u00a045) and straight group (C2\u20137 Cobb angle \u226410\u00b0, <jats:italic>n<\/jats:italic>\u00a0=\u00a055).
