Design outcomes
Primary
| Measure | Time frame |
|---|---|
| - Clinical outcome, scored by the Neck Disability Index at 52 weeks after start of treatment - Fracture healing, assessing union (union or non-union) and stability at 52 weeks after start of treatment Union will be defined by evidence of bone trabeculae crossing the fracture site and absence of sclerotic borders adjacent to the fracture site, assessed using computed tomography (CT). Fracture stability will be assessed using cervical dynamic X-rays in lateral projection. A maximum of 2 mm movement at the fracture site is considered stable. Imaging data will be sent to the coordinating centre and will be judged by independent assessors (neuroradiologists) who are blinded to the results. | — |
