The investigators will include 150 patients with a stable cervical fractures of vertebra C3-C7 with a Subaxial Cervical Spine Injury Severity (SLIC) Score 1-3 and randomize them in to two similar groups. One group will be treated with a cervical collar for 6 weeks and the other group will be treated for 12 weeks. There will be a clinical check up and a CT scan at 1, 6, 12 and 26 weeks after the initial injury. The investigators will compare the results between the two groups when it comes to fracture healing (CT based), level of function, pain and the length of sick leave with a total of 6 months of follow up.
