Here another distraction injury. Vertebral bodies show marrow edema as a result of a fracture. There is not much else happening here. Analogous to clasifjcacion 3-column classification of Denis, some investigators consider the sternum as the fourth column in upper thoracic spinal fractures and recognize it as an independent variable in the assessment and treatment of these patients 5.
FRACTURAS: clasificación AO/ASIF by yasmin gonzalez on Prezi
Distraction A dde injury is separation or pulling apart of two adjacent vertebrae. The PLC serves as a posterior “tension band” of the spinal column and plays an important role in the stability of the spine 3.
However the most important findings are the horizontal fractures of the posterior elements. Even though there is not much displacement at this moment, we should probably call this translation injury. A posterior spondylodesis was performed.
There were no statistically significant differences among these values, but there were epistemological differences. Posterior Ligamentous Complex The PLC serves as a posterior “tension band” of the spinal column and plays an important role in clasificacuon stability of the spine 3.
So we should call this a translation fracture with anterior displacement. The sagittal reformatted image also shows the cortical disruption.
The role of the radiologist is to report the following: Holmbergs classification provides a better anatomical description. Pitfalls in diagnosing a compression fracture are: Morphology and PLC are scored separately. Furthermore, the word stability itself is ambiguous and may refer to direct osseous stability; it may refer to neurological stability and finally, to long-term ligamentous stability. Three observers, with similar degree of training, evaluated the X-rays independently and scored each one of them using the 3 scales compared herein.
Distraction – 4 points PLC: In many cases, however, there is no good correlation with the necessity for surgery.
Burst – 2 points PLC: This next case has a great teaching point. In the Denis classification a burst fracture is classified as a two-column injury, calling it unstable and requiring fractueas stabilization.

A total of more than 4 points indicates surgical treatment. Subsequent modifications of the Denis classification have recognized that with an intact posterior ligamentous complex PLCtwo-column unstable injuries can be successfully treated non-surgically 3.
Patients with a rigid spine such as in ankylosing spondylitis, DISH and rheumatoid arthritis are more susceptible to spinal fractures, even after clasificaccion trauma 6. How would you describe the morphology and the PLC? A torn PLC has a tendency not to heal and can lead to progressive kyphosis and collapse.
The different morphology patterns will be discussed more in detail in the following chapter. Here is a patient with distraction on the anterior side. Continue with the MR. Burst is the result of compression with severe axial loading. Avulsion fractures or transverse fractures of spinous processes or articular facets.
Some of the injuries thought to be due to extension mechanisms, however, turn out to be due to flexion and vice versa. Here a typical case of translation. The morphology is burst 2 points The PLC is injured with a fracture through the adjacent spinous processes. Continue with the axial images. The lateral view shows the typical features of a burst fracture.
