Arm && Interventions

Group	Intervention	Description
Laminoplasty Group	Cervical laminoplasty surgery	Patients who underwent cervical laminoplasty surgery due to myelopathy.
Laminectomy and Fusion Group	Cervical laminectomy and fusion surgery	Patients who underwent cervical laminectomy and fusion surgery due to myelopathy.

Primary Outcome Measures

Name	Time	Method
Change of Sagittal Lordosis Angle	baseline, 12 months post-treatment and through study completion, an average of 10 year	Measured by lateral X-Ray image. The change of lordosis was calculated and compared.
Reoperation rate	through study completion, an average of 10 year	Any reoperation involving the same segments or adjacent segments will be calculated.
Change of Neck Disability Index (NDI)	baseline, 12 months post-treatment and through study completion, an average of 10 year	Ranging from 0%-100%. A higher score indicates more patient-rated disability.
Change of Japanese Orthopaedic Association Score (JOA)	baseline, 12 months post-treatment and through study completion, an average of 10 year	Total score 0-17. The lower the score the more severe the deficits.

Secondary Outcome Measures

Name	Time	Method
Change of Range of Motion	baseline, 12 months post-treatment and through study completion, an average of 10 year	Measured by dynamic X-Ray image.
Change of Pain Scores on the Visual Analog Scale (VAS)	baseline, 12 months post-treatment and through study completion, an average of 10 year	Ranging from 0-10. A higher score indicates more severe pain.
Complication rate	through study completion, an average of 10 year	Any complications related to surgery will be recorded.
