One of the fractures is a typical avulsion. Notice the horizontal band of density, which is often described as sclerosis.
Morphology and PLC are scored clasificaciom. El objetivo de este estudio fue evaluar la reproducibilidad y acuerdo interobservador de las clasificaciones Holmberg, Gartland y AO.
The role of the radiologist is to report the following: The lateral view shows the typical features of a burst fracture. This is merely a sign of trabecular impaction in an acute fracture.

So this is a distraction fracture, also known as Chance fracture. There is a spinous process fracture, which is not a key element but a frequently associated injury. How would you describe the morphology and the PLC?
It is a severe injury since there is a high chance of cord injury when its osseous and ligamentous supporting structures are pulled apart. Burst – 2 points There is retropulsion of a body fragment black arrow PLC: Distraction A distraction injury is separation or pulling apart of two adjacent calsificacion.
Here a fracture that just looks like another compression fracture on the lateral view.
Fractkras classification is the most recommendable one. The PLC is composed of the supraspinous ligaments, interspinous ligaments, articular facet capsules, and ligamenta flava figure.
Case 4 Look at the images. There were no statistically significant differences among these values, but there were epistemological differences. The sagittal reformatted image also shows the cortical disruption. Widening or dislocation of facet joints. Transverse process fractures A rib fracture These are typical findings in translation-rotation fractures.
The morphology is of a vertebral fracture with retropulsion of a fragment, i. You can see the edema related to the fracture of the vertebral body and the massive edema in the paraspinous muscles. Scroll through the images.
Sternum fracture The image shows a vertebral fracture with a transverse fracture of the spinous process, but also fractutas fracture of the sternum. The MRI demonstrates rupture of the flava ligaments, interspinous and supraspinous ligaments as well as fracture of the posterior elements and compression of the vertebral body.
A distraction injury is separation or pulling apart of two adjacent vertebrae.

A parameter can be scored points and the total score is the sum of fracturzs parameters with a maximum of 10 points. 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.
Again look at the first MR-images and decide what is going ed. There is not much else happening here. However the distraction is the most important finding, i. In this case the main findings are the horizontal fractures of the posterior elements. In the TLICS this means 3 points for the morphology and 3 points for the PLC, which makes a total of 6 points indicating the need for surgical stabilization.
Continue with the MR-images. Most classification systems of spine injuries are based on injury mechanisms and describe how the injury occurred. The purpose of this study was to assess the reproducibility and interobserver agreement of the Holmbert, Farcturas and AO classifications. Analogous to the 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 feacturas patients 5.
Only the level with the highest score counts. If there was a lot of fluid in the joint, we should call this indeterminate.

A total of more than 4 points indicates surgical treatment. Since in both cases the TLICS score based on imaging will be high, there is usually an indication for surgical treatment. Three observers, with similar degree of training, evaluated the X-rays independently and scored each one of them using the 3 scales compared herein.
The posterior vertebral cortex is intact. This is all based on the premise that a fracture caused by forward flexion should be treated by undoing the flexion by positioning the patient in an extension brace, or by surgical intervention correcting the spinal column clawificacion extension.
Burst fracture This is the severe variant of a compression fracture with higher risk of neurologic deficits. Usually the morphology matches the injury mechanism, but sometimes it does not.
Translation – 3 points PLC: On the right with kyphosis. 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 ak posterior ligamentous complex.
