FRACTURAS: clasificación AO/ASIF by yasmin gonzalez on Prezi

Myelopathy or nerve compression. Anterior displacement of C7 to Th1. A total of more than 4 points indicates surgical treatment. There is a spinous process fracture, which is not a key element but a frequently associated injury. On the AP-view notice the subtle widening of the interpedicular distance compared to the levels above and below. This density does not mean that it involves an older fracture that is already healing with sclerosis.

At first we thought that little pieces of bone didn’t matter, clasififacion they may be the most important sign of a major injury on a CT-scan. That is until we zoom in and look at the distance between the spinous processes. The fact that these little pieces of bone have been so severely displaced means there has to be a major injury.


On the right with kyphosis. Compression of the spinal cord. Morphology and PLC are scored separately.

You have to decide what you think is the main issue: Pitfalls in diagnosing a compression fracture are: Distraction – 4 points PLC: Continue with the MR-images. So here is a typical case of distraction.

Both of these commonly used systems fail to systematically take into account the neurological status of the patient and the indication for MRI to determine the integrity of the posterior ligamentous complex.

The morphology is of a vertebral fracture with retropulsion of a fragment, i.

There is major disruption of the PLC of both the ligamenta flava and the interspinous ligament. Only the level with the highest score counts. You could call these compression fractures. Posterior Ligamentous Complex The PLC serves as a posterior “tension band” of the spinal column and plays an important role in the stability of the spine 3. The key point in this case is that you should not describe this morphology as burst – 2 points.

Vertebral body translation or rotation. This means that a patient can be treated non-surgically. Case 6 Look at the images. Translation – Rotation This type of fracture includes all fractures that are the result of displacement in the horizontal plane: The difference between the correlation coefficients was 0.

The facet joints act against rotational forces. When there are several fractures, each level has to be scored separately. Case 1 Scroll through the images. The mean correlation coefficient of the AO classification was 0. Sternum fracture Rigid spine Multiple rib fractures at the same levels Non braceable Wounds Pre-existing deformities Sternum fracture The image shows a vertebral fracture with a transverse frxcturas of the spinous process, but also a fracture of the sternum.

Using the popular Denis three-column classification may lead to another situation since it uses the terms stable and unstable. The teaching point is: Burst – 2 points PLC: TLICS score based on imaging is 7 points:
