In which position should the cervical spine be placed for the correct fitting of a rigid cervical collar?

The correct position for fitting a rigid cervical collar is with the cervical spine in a neutral position. This alignment ensures that the head and neck are in a natural state, minimizing any additional strain on the cervical vertebrae and associated soft tissues. A neutral position maintains the normal curvature of the cervical spine, which is crucial for comfort and effectiveness in stabilizing the neck.

When the cervical spine is placed in hyperextension or flexion, it could lead to discomfort, increased pressure on certain vertebrae, and potential harm to the spinal cord or surrounding structures. Extension may also alter the natural curvature, causing improper fit and effectiveness of the collar. Therefore, fitting the collar with the cervical spine in a neutral position helps provide optimal support and safety for patients.
