Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change of Japanese Orthopaedic Association Score (JOA)	Total score 0-17. The lower the score the more severe the deficits.	baseline, 12 months post-treatment and through study completion, an average of 10 year
Primary	Change of Neck Disability Index (NDI)	Ranging from 0%-100%. A higher score indicates more patient-rated disability.	baseline, 12 months post-treatment and through study completion, an average of 10 year
Primary	Change of Sagittal Lordosis Angle	Measured by lateral X-Ray image. The change of lordosis was calculated and compared.	baseline, 12 months post-treatment and through study completion, an average of 10 year
Primary	Reoperation rate	Any reoperation involving the same segments or adjacent segments will be calculated.	through study completion, an average of 10 year
Secondary	Change of Pain Scores on the Visual Analog Scale (VAS)	Ranging from 0-10. A higher score indicates more severe pain.	baseline, 12 months post-treatment and through study completion, an average of 10 year
Secondary	Change of Range of Motion	Measured by dynamic X-Ray image.	baseline, 12 months post-treatment and through study completion, an average of 10 year
Secondary	Complication rate	Any complications related to surgery will be recorded.	through study completion, an average of 10 year
