Chance fracture

Introduction to Chance fracture Also known as flexion stretch fracture, it is more common when the highway seat belt suddenly brakes when the upper body suddenly bends forward. Such fractures have often been encountered clinically in recent years and can also be considered as a special type of flexion fracture. basic knowledge The proportion of sickness: 0.01% Susceptible people: no specific people Mode of infection: non-infectious Complications: swelling

Chance fracture cause

(1) Causes of the disease

When the upper part of the body moves forward abruptly, this damage is often caused during flexion.

(two) pathogenesis

The traffic accident on the expressway is frequent. Most of the occupant's body is rapidly displaced forward and flexed at the moment of the crash. At this time, the front of the vertebral ganglion (column) is the pivot, and the posterior column ligament or spinous process is broken by the tension. And extending to the middle column, can also reach the front column, the typical Chance fracture fracture line is from the back to the front, starting from the spinous process, through the lamina, vertebral arch vertebral body, atypical, its damage is the spine The superior ligament ruptures first, and the posterior interspinous ligament, the ligamentum flavum, the posterior longitudinal ligament and even the intervertebral space completely rupture.

Chance fracture prevention

Pay attention to rest, work and rest, life in an orderly manner, and maintaining an optimistic, positive and upward attitude towards life can be of great help in preventing diseases.

Chance fracture complications Complications swelling

Can be complicated by spinal cord involvement symptoms.

Chance fracture symptoms Common symptoms Joint swelling vertebral division internal bleeding

Similar to the general thoracolumbar flexion fracture, the local symptoms of the vertebral segment are obvious and may be associated with spinal cord involvement, but the incidence is lower and to a lesser extent.

Chance fracture examination

X-ray shows transverse fractures and pedicles with horizontal tear fractures (also occurring in the spinous processes and articular processes), the spine process is widened by the level of spinous process, the posterior margin of the vertebral body or the injured plane vertebrae The posterior space gap is widened, because the scan line is parallel to the fracture plane, so no CT scan is positive, and the sagittal plane is more meaningful.

Diagnosis of Chance fracture

According to the injury site and mechanism, the clinical features and imaging findings are not difficult to make a diagnosis. A clear X-ray lateral radiograph can identify the damaged part and the degree of vertebral division. Patients with spinal cord symptoms should undergo CT scan. Or MRI check.
