Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome measure is the rate of fusion in the two treatment groups. | — |
Secondary
| Measure | Time frame |
|---|---|
| Further objectives of the study are to assess clinical outcome parameters in both groups. Such parameters are primarily assessed using questionnaires (Neck Disability Index, Myelopathy Disability Index, Visual Analogue Scales for pain in the arm and neck and Prolo*s economic and functional scale.) The incidence and severity of adverse events are also compared between groups. | — |
