Fig. 4From: Impact of cervical and global spine sagittal alignment on cervical curvature changes after posterior cervical laminoplastyFull-length spinal films and enlarged cervical spine images in the low T1S low SVA group, the high T1S low SVA group, the low T1S high SVA group, and the high T1S high SVA group. Compared with the other three groups, the patients with high T1S and high C7 SVA had significant loss of cervical lordosis after surgery. T1S: T1 slope; SVA: sagittal vertical axisBack to article page
