Most fractures of the cervical spine are considered stable and treated with a rigid cervical collar. However no studies have to date been published addressing the length of treatment. There seems to be a significant dissimilarity between hospitals within and between countries with the length of collar treatment varying from 6 to 12 weeks. At the neurosurgical department at Oslo University Hospital, Ullevål the standard length of treatment for a stable cervical fracture is 12 weeks. This study seeks to establish whether 6 weeks of collar treatment for a specific subtype of stable fractures in the cervical spine is sufficient.
