---|---|
Prospective
All patients for whom the decision has been made to have the Synergy Disc system implanted and give informed consent will be enrolled in this study, following country-specific requirements.
|
motion preservation disc
|
Retrospective
Patients who have previously received the Synergy Disc system in the last ten years are eligible for inclusion in the retrospective data collection; a waiver of consent, or an informed consent, for the retrospective data collection from the medical records of the implanting surgeon will be sought per country-specific regulations.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Neck Disability Index (NDI)
Time Frame: 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.
|
12 months
|
Device Related or Device Procedure Related Adverse Events
Time Frame: 12 months
|
Absence of major device related adverse events defined as radiographic failure, neurologic failure or failure by adverse event
|
12 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Neck and Arm Pain Measurement
Time Frame: 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.
|
pre-operative, 6 week, 3 month, 6 month, 12 month, 24 month
|
Patient Satisfaction
Time Frame: 6 week, 3 month, 6 month, 12 month, 24 month
|
patient completed questionnaire on their satisfaction with the disc replacement surgery
|
6 week, 3 month, 6 month, 12 month, 24 month
|
Motor and Sensory Function in the Arm
Time Frame: 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)
|
pre-operative, 6 week, 3 month, 6 month, 12 month, 24 month
|
Nurick's Criteria
Time Frame: pre-operative, 6 week, 3 month, 6 month, 12 month, 24 month
|
Disease status as characterized by physician at each time point
|
pre-operative, 6 week, 3 month, 6 month, 12 month, 24 month
|
Odom's criteria
Time Frame: 6 week, 3 month, 6 month, 12 month, 24 month
|
surgical outcome characterized by physician at each post operative visit
|
