About this study
Official title: A Prospective, Feasibility, Multi-Center Nonrandomized Clinical Trial Evaluating the Safety and Effectiveness of NuNec® Cervical Arthroplasty System
The objective of this study is to evaluate long-term safety and effectiveness of the NuNec® Cervical Arthroplasty System in a small patient population. The NuNec device is currently CE marked and commercially available in Europe.
Read the detailed description
The NuNec® feasibility study is a prospective, multi-centered, non-randomized clinical trial. Only patients who have been diagnosed with single level, C3 to C7, symptomatic cervical degenerative disc disease and have failed at least 6 weeks of conservative treatment or present signs of progression of spinal cord/nerve root compression with continued non-operative care will be enrolled.
Patients will be evaluated preoperatively and postoperatively at discharge, 6 weeks, 3, 6, 12 and 24 months.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
NuNec Cervical DiscDevice
Also called NuNec Cervical Arthroplasty System
Patients will be enrolled and implanted with the NuNec device at a single level C3 to C7.
| Study group | Role | What they receive |
|---|---|---|
| NuNec Cervical Disc | Experimental | Each patient will be implanted with the NuNec Cervical Disc in a single level from C3 to C7. Postoperatively, patient evaluated at discharge, 6 weeks, 3, 6, 12 and 24 months. Receives: Device: NuNec Cervical Disc |
What is being measured
The primary outcome is the main question the study is designed to answer.
Neck Disability Index (NDI) Score Improvement of at Least 15 Points
The Neck Disability Index is a patient reported outcome measure for self-rated disability due to neck pain. Each of the 10 items is scored from 0 - 5. The maximum score is therefore 50. The obtained score can be multiplied by 2 to produce a percentage score. A higher score would indicate that the patient did not improve.
Measured: At 24 months
Visual Analog Scale (VAS) Improvement of 2.0 cm for Neck Pain
The pain Visual Analog Scale is a uni-dimensional measure of pain intensity, represented by a 100 mm line, anchored by "no pain" (score of 0) and "pain as bad as it could be" or "worst imaginable pain" (score of 100 [100-mm scale]). A higher score would indicate that the patient had a worse outcome.
Measured: At 24 months
Serious Adverse Events Related to the Device
The number of serious adverse events have been recorded
Measured: Up to 24 months
Device Failures or Removals, Revisions, Re-operations
The failures or re-operations or supplemental fixation at the treated level
Measured: Up to 24 months
Secondary outcomes (2)
Patient Satisfaction
As assessed on patient questionnaire.
Measured: At 24 months
Absence of Device Migration or Subsidence
Absence of device migration > 3mm; Absence of device subsidence > 3mm
Measured: Up to 24 months
