Figure 3

Typical case imaging. 42 years female, felt both upper limb numbness and muscle weakness for 2 years. She was diagnosed as cervical spondylosis and treated with double-door laminoplasty. The preoperation JOA score and postoperation JOA score are, respectively, 11 and 15. (a), (b), (c), and (d) were, respectively, lateral view, flexion view, extension view of X-ray, and MRI scan before the surgery. (e), (f), (g), and (h) were, respectively, lateral view, flexion view, extension view, and MRI scan at 2 years follow-up. Angle and were cobb angle between C2 and C7. Angle and were T1 slope angle. The angle between line AB and CD represent the intervertebral space angle (, ; , ; , ).
