severe rigid cervical kyphosis

Fig. 1, (A), (B) preoperative standard anterior and lateral position of cervical vertebra; scoliosis deformity can be observed; (C), (D) preoperative cervical flexion and extension; severe cervical kyphosis, C2-C7 kyphosis angle is about 90 ° Figure 2, (A) CT sagittal view shows C3-C6 vertebral body fusion; C3-C6 lamina is absent, facet joint fusion. (B)MRI shows severe spinal cord compression and cervical kyphosis. Figure 3 A. three months after operationCT three-dimensional imaging (C2-C7 kyphosis angle is about 20 °), B. six months after operation X-ray lateral position (C2-C7 kyphosis angle is about 20 °), C. six months after operation CT three-dimensional imaging, D. two years after operation X-ray lateral position (C2-C7 kyphosis angle is about 25 °), E. two years after operation CT three-dimensional imaging.
