I. Nerve root type cervical spondylosis
Mostly seen in people over 40 years of age, the disease starts slowly and there is no history of trauma. However, the disease can be triggered when the head is traumatized by various causes. The main symptoms include neck, shoulder and back pain and cervical nerve irritation or compression.
1. There are different degrees of deformity and stiffness in the neck.
2. The pressure point is below the transverse process of the cervical spinal nerve and the area innervated by its dorsal branch.
3. Positive brachial plexus nerve pull test.
4, Positive intervertebral foramen compression test.
5.Positive subacromial pressure test.
6. When the cervical nerve is stimulated, the distal part of it shows painful hypersensitivity in the early stage; when it is compressed more heavily or for a longer period of time, the distal part of it shows hyposensitivity.
7.When the main nerves of the biceps and triceps tendons are excited, the tendon reflexes are active, and vice versa, the tendon reflexes are reduced or disappear.
8. When the nerve roots are compressed, the strength of the muscles they innervate is reduced in the mild cases, and muscle atrophy can be seen in the severe cases.
Second, spinal cord type cervical spondylosis
Clinically, it can be divided into simple spinal cord type and mixed spinal nerve root type according to whether the compression is located in the center of the spinal cord or on one side. The clinical symptoms are as follows
1. Upper extremity symptoms: simple motor disorder, simple sensory disorder or both sensory and motor disorder in one or both upper extremities.
2.Lower extremity symptoms: neurological dysfunction in one or both lower extremities.
3.Lateral symptoms: sensory-motor disorders appearing in the upper and lower extremities on the same side.
4.Crossed symptoms: sensory or motor disorders appearing in one upper extremity and the contralateral lower extremity.
5.Extremity symptoms: neurological dysfunction in the extremities.
6.Head symptoms: mainly manifested as headache, dizziness or scalp pain.
7. Sacral nerve symptoms: manifested as urination or defecation disorders.
C. Vertebral artery type cervical spondylosis
Clinical manifestations are
1. Typical symptoms of vertebral artery insufficiency of blood supply: episodic vertigo, diplopia with nystagmus, sometimes nausea, vomiting, and even tinnitus and deafness.
2, sudden collapse.
3.Brainstem symptoms: numbness of limbs, abnormal sensation, holding objects to the ground.
4.Occipital throbbing pain.
5.Episodic coma.
IV. Sympathetic cervical spondylosis
Sympathetic excitation symptoms.
1. Headache or migraine, dull head, dizziness, occipital pain or posterior neck pain.
2. Enlarged eye fissures, blurred vision, dilated pupils, painful eye sockets, dry eyes, and gold stars in the visual field.
3. Increased heart rate, heart rhythm disturbance, precordial pain and increased blood pressure, etc.
4.The limbs are afraid of cold and cold, the local temperature is low, or the limbs have a tingling sensation when they are cold, followed by redness and swelling or pain aggravation.
5.Disorder of sweating. Sympathetic nerve suppression symptoms: dizziness, droopy eyelids, lacrimation, nasal congestion, bradycardia, low blood pressure, increased gastrointestinal motility or warmth, etc.
