Cervical vertebrae have obvious degenerative changes
Introduction
Introduction Cervical degenerative disease is an aging phenomenon in humans. When people are over 30 years old, aging will gradually appear. The cervical vertebra will also produce various aging, which is characterized by cervical edge degeneration, bone hyperplasia, increased brittleness, joint capsule elasticity, cervical disc degeneration, etc. The blood vessels are compressed and stimulated, and the nerves in our head are from the cervical nerves. If the cervical spine undergoes degenerative diseases, the nerves passing through this area will be affected, causing headaches. Most of the young people have cervicogenic headaches, mostly because they study and work for a long time. The neck muscles continue to contract in order to maintain the posture of the head. The muscles are tense and the muscles of the neck are secondary, which can release some pain. Substance, causing head pain.
Cause
Cause
(1) Causes of the disease
It is caused by longitudinal flexion compression.
(two) pathogenesis
Mainly caused by longitudinal flexion compression, the degree of compression of the anterior edge of the vertebral body is different, and the local pathological anatomical changes caused by the vertebral body are different. There are few secondary changes in the light type, and 60% to 70% of the cases belong to this type. In addition, a small number of vertebral bodies are severely compressed, the wedge-shaped widening of the spinous process gap and the wedge-shaped compression of the vertebral body can cause obvious vertebral instability, and even secondary occlusal occlusion variation (subluxation) and spinal cord traction Pulling, and the central anterior spinal artery syndrome can occur, the damage has been from the simple anterior column to the middle column and the posterior column, which is a three-column injury, more common in the neck 5,6 vertebra, followed by the neck 4,7 segment.

In addition to the general symptoms of cervical spine injury, the patient mainly showed that the neck was forced to position, difficulty in raising the head, and tenderness in the posterior small joint. If the compression is severe, or the spinal canal stenosis, or the cervical vertebra has a significant degenerative change, severe spinal cord or spinal nerve root involvement may occur, and should be carefully examined to determine the extent of the condition.
1. The history of trauma is mainly caused by longitudinal flexion of flexion; the lateral wedge compression is mostly due to the lateral curvature of the cervical vertebra.
2. Clinical manifestations As mentioned above, the lighter is mainly neck symptoms, while the severe ones have a series of symptoms due to cervical vertebral instability. At this time, a detailed examination should be performed according to the requirements of the nervous system examination to confirm whether there is a symptom of spinal cord involvement.
3. Imaging examination According to the X-ray positive position and lateral position, the diagnosis can be confirmed. On the conventional X-ray film, the spinous process gap can be wedge-shaped widened, the vertebral body is also wedge-shaped, and there can be triangular bones below the vertebral body. Among them, those with severe wedge shape are often accompanied by different degrees of spinal cord symptoms. MRI or CT examination should be used for such cases. Myelography can also be used in advanced cases (not suitable for early post-injury, but CTM can be used as appropriate).
Diagnosis
Differential diagnosis
The cervical vertebra has a differential diagnosis of degenerative changes:
1. Bone spur formation at the posterior margin of the vertebral ganglion: degeneration of the intervertebral disc is one of the manifestations of cervical spinal stenosis. Congenital cervical spondylotic stenosis is caused by fetal vertebral canal dysplasia, resulting in sagittal diameter of the cervical spinal canal. The stenosis causes the spinal cord and spinal nerve roots to be stimulated or oppressed, causing a series of clinical symptoms.
2, vertebral segmentation: Chance fracture with X-ray examination of the lateral radiograph can determine the extent of damage and vertebral division.
