Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Neck Disability Index (NDI) | 12 months | 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. |
| Device Related or Device Procedure Related Adverse Events | 12 months | Absence of major device related adverse events defined as radiographic failure, neurologic failure or failure by adverse event |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Neck and Arm Pain Measurement | pre-operative, 6 week, 3 month, 6 month, 12 month, 24 month | 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. |
| Patient Satisfaction | 6 week, 3 month, 6 month, 12 month, 24 month | patient completed questionnaire on their satisfaction with the disc replacement surgery |
| Motor and Sensory Function in the Arm | pre-operative, 6 week, 3 month, 6 month, 12 month, 24 month | maintenance or improvement in neurologic status compared with baseline will be assessed using a defined numeric scale ranging from 0 (normal) to 5 (deficit) |
| Nurick's Criteria | pre-operative, 6 week, 3 month, 6 month, 12 month, 24 month | Disease status as characterized by physician at each time point |
| Odom's criteria | pre-operative, 6 week, 3 month, 6 month, 12 month, 24 month | surgical outcome characterized by physician at each post operative visit |
