| Measure | Description | Time Frame |
|---|---|---|
| Neck Disability Index (NDI) | Neck disability Index improvement of >15 pts (out of 100) in subjects by 12 months post operative compared with baseline. A lower score is a better score. | 12 months |
| Device Related or Device Procedure Related Adverse Events | Absence of major device related adverse events defined as radiographic failure, neurologic failure or failure by adverse event | 12 months |
| Measure | Description | Time Frame |
|---|---|---|
| Neck and Arm Pain Measurement | Pain will evaluated by the Visual analog scale (VAS) (place a line from zero where there is no pain to 10 which is the worst pain imaginable), by NRS (circle a number from zero to ten where zero equals no pain and ten is worst imaginable) to or a verbal description that the doctor writes down, per the site's Standard of Care. A change of at least 20 mm will be considered clinically significant. Neck pain as measured on a 100mm VAS at baseline and at each follow-up timepoint. Left and Right arm/shoulder pain as measured on a 100 mm VAS at baseline and at each follow up time-point. |
