The protrusion of the bones in the back of the neck is the first thing to rule out if there is a change in the curvature of the cervical spine. If the cervical spine is straightened, it is often accompanied by protrusion of the spinous process in the cervical spine when working at a desk. For the straightening of the cervical curvature, the first line of X-ray examination, in addition to traction, as well as cervical pillow to improve the curvature of the cervical spine when sleeping, usually must pay attention to reduce the ambulatory work time.
