Serial number at source M0617
Study hypothesis Aim of the study was to determine the effect, if any, of wearing a hard collar following Anterior Cervical Discectomy (+/- Grafting) on pain, range of movement and function. No statistically or clinically significant differences were found between collar and no collar wearing groups on any outcomes, although patient compliance was a problem due to the inconvenience of wearing a collar. The need for providing patients with information and
reassurance to mitigate the need for collars is highlighted.
