Cervical vertebral body wedge compression fracture
Introduction
Introduction to cervical vertebral wedge compression fracture It is more common in clinical practice, the symptoms are mild, and the violence mainly affects the anterior column of the vertebral ganglia, so it is mostly stable. There may also be a small number of cases with posterior small joint dislocation and vertebral instability (more with spinal cord injury), which should be noted in the treatment. basic knowledge The proportion of illness: 0.012% Susceptible people: no special people Mode of infection: non-infectious Complications: spinal cord injury spinal radiculitis
Cause
Causes of cervical vertebral wedge compression fracture
Causes:
It is caused by longitudinal flexion compression.
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.
Prevention
Cervical vertebral wedge compression fracture prevention
Prevent violent injuries.
Complication
Complications of cervical vertebral wedge compression fracture Complications spinal cord injury radiculitis
Severe injury can be complicated by the involvement of the spinal cord or nerve roots.
Symptom
Cervical vertebral wedge compression fracture symptoms Common symptoms Forced position lumbar spinal canal stenosis nerve root damage
In addition to the general symptoms of cervical spine injury, the patient is mainly characterized by forced neck position, difficulty in raising the head, and tenderness in the posterior small joint, such as severe compression, or spinal stenosis, or cervical degenerative changes. At the time, severe spinal cord or spinal nerve root involvement may occur and should be carefully examined to determine the extent of the condition.
Examine
Examination of cervical vertebral wedge compression fracture
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 also has a wedge shape, and there can be a triangular bone block under the vertebral body, wherein the wedge shape Patients with severe symptoms are often accompanied by different degrees of spinal cord symptoms. MRI or CT examination should be used for such cases, and myelography should be selected for advanced cases (not suitable for early post-injury, but CTM can be used as appropriate).
Diagnosis
Diagnosis and diagnosis of cervical vertebral wedge compression fracture
History of trauma
Mainly due to longitudinal flexion of flexion; lateral wedge compression, mostly because the cervical vertebra is in a side-bend state.
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, detailed examination should be performed according to the nervous system examination to confirm whether there is 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 also has a wedge shape, and there can be a triangular bone block under the vertebral body, wherein the wedge shape Patients with severe symptoms are often accompanied by different degrees of spinal cord symptoms. MRI or CT examination should be used for such cases, and myelography should be selected for advanced cases (not suitable for early post-injury, but CTM can be used as appropriate).
