The main cause of neurogenic cervical spondylosis is acute inflammation of the affected synovial joints, inflammatory swelling of the synovial membrane and joint capsule, often combined with joint effusion, stimulation of the adjacent nerve roots and sinus spinal nerve branches, muscle tension in the neck and shoulder, and swelling of the neck and shoulder in some patients. What are the main manifestations of neurogenic cervical spondylosis? 1.Cervical symptoms may vary in severity depending on the cause of the radicular compression, mainly due to the herniated nucleus pulposus, which is accompanied by obvious neck pain due to the direct stimulation of the local sinus nerve, paravertebral muscle pressure and formal cervical posture, and direct pressure pain or percussion pain between the spinous process or spinous process of the cervical spine is mostly positive, and these manifestations are especially obvious in the acute stage. If the symptoms are caused by simple degeneration and osteophytes, the neck symptoms are mild or even no special findings. 2. Radicular pain is the most common, and its extent corresponds to the area of distribution of the spinal nerve roots in the affected vertebral segment. At this time, it must be distinguished from dry pain (mainly radial nerve trunk, ulnar nerve trunk and median nerve trunk) and plexiform pain (mainly cervical plexus, brachial plexus and axillary plexus), and radicular pain is accompanied by other sensory disorders in the distribution area of the nerve root, among which numbness of the fingers, sensory allergy of the fingertips and loss of skin sensation are common. 3. Root muscular dysfunction, which is obvious in those who have first compression of the anterior root. In the early stage, the muscle tone is increased but soon weakened and myasthenia gravis appears, and its involvement is only limited to the muscle groups innervated by the spinal nerve root. 4, tendon reflex changes, that is, the involvement of spinal nerve roots involved in the reflex arc appears abnormal. In the early stage, the reflexes are active, but in the middle and late stages, they are diminished or disappear.
