Measurements of spinal-pelvic parameters.
A. Coronal plane of full-length spine X ray. There was no clear scoliosis (Cobb angle<10°). B.C. Sagittal plane of full-length spine X ray. Measurements of sagittal spinal parameters include: sagittal vertical axis (SVA), thoracic kyphosis (TK), thoracolumbar kyphosis (TLK), lumbar lordosis (LL); pelvic parameters include: sacral slope (SS), pelvic tilt (PT) and pelvic incidence (PI).

Modic type I change: hyperintense on T2WI (A↘), hypointense on T1WI (B↘) at inferior endplate of L4. Modic type II change: hyperintense on T2WI (C upper↘), hyperintense on T1WI (D upper↘) at superior endplate of L3. Modic type III change: hypointense on T2WI (C inferior↘), hypointense on T1WI (D inferior↘) at superior endplate of L4.

A. The distribution of Modic changes. B. The intervertebral disc degeneration of different spinal levels.
Fig 4.
Modic changes were significantly correlated with intervertebral disc degeneration; the amount of Modic changes were significantly correlated with lumbar lordosis (LL), sacral slope (SS) and pelvic tilt (PT).
