Detailed Description
The purpose of study is to confirm the safety and and performance of the A-SPINE's products for using 2 years. This post-market clinical follow-up study use questionnaires such as Visual Analog Scale (VAS), the Neck Disability Index (NDI), or the Oswestry Disability Index (ODI) to evaluate the clinical improvement effects. Subjects will be evaluated at pre-operation, 6 months, 12 months, and 2 years post treatment. Finally, analyze the clinical outcome, fusion rate, and adverse events.

Outcome Measures
Primary Outcome Measures
- Visual Analogue Scale- Change from baseline at 2 year [Change from baseline at 2 year]
Visual Analogue Scale is a patient-reported outcome measure. The scale ranges from 0 to 10. A score of 0 represents no pain, while a score of 10 represents extreme pain. Compare baseline and postoperative improvement VAS scores.
Secondary Outcome Measures
- Neck Disability Index [Baseline, 6 months, 12 months, 24 months]
The NDI is a questionnaire that is commonly used in clinical trials to measure the self-reported functional status of patients with neck pain.The ten questions are measured on a 6-point scale from 0 (no disability) to 5 (full disability). Compare baseline and postoperative improvement NDI scores.
- Oswestry Disability Index [Baseline, 6 months,12 months, 24 months]
The ODI is a questionnaire that is commonly used in clinical trials to measure the self-reported functional status of patients with neck pain.The ten questions are measured on a 6-point scale from 0 (no disability) to 5 (full disability). Compare baseline and postoperative improvement ODI scores.
- Number of Device-related Adverse Events [Baseline, 6 months,12 months, 24 months]
Adverse events associated with the device will be assessed at each follow-up visit and the number of cases at the 2-year follow-up will be counted.
- Fusion Rate [Baseline, 6 months,12 months, 24 months]
Use X-ray or CT to detect the spine fusion.
