What does cervical spine arch mean?

The spine of the human body has physiological curvature in the sagittal plane, that is, viewed from the side, that is, cervical spine forward, thoracic spine backward, lumbar spine forward, sacrococcyx backward, and has a certain curvature range. In clinical practice, sometimes patients will encounter cervical spine straightening, flattening, or even kyphosis, accompanied by degenerative hyperplasia of cervical spine, disc degeneration, etc., compressing spinal cord, nerve root or vertebral artery. At this time, it is necessary to distinguish whether the clinical examination has nerve root compression symptoms, such as numbness and muscle weakness in both shoulders and upper limbs, and whether cervical spondylosis has been shown after cervical spine straightening. There is also a case of acute muscle injury in the neck, cervical spine will also show straightening, physiological curvature disappears, but there is no nerve root injury symptom, and it can be treated according to local soft tissue injury.
