Sagittal fracture of vertebral body and posterior element.
Ossification of the spinal ligaments and calcification of the annulus fibrosus alter the biomechanics of the spine, creating long lever arms and limiting the ability to absorb even minor impacts. Modifiers Modifiers are other factors which can affect the decision of appropriate treatment: The name is derived from the typical fracture following a fall from height and landing on the feet.
The interobserver agreement was assessed using Kendalls Tau-b ratio; the arithmetic mean was calculated and the ratios were compared with Fishers transformation. According to Landis and Koch, the Holmberg and Gartland classifications show a substantial agreement, while the AO classification showed a moder ate agreement.
Case 6 Look at the images.
Translation – 3 points PLC: What are the findings? But there are also little pieces of bonethat have avulsed at least 10mm away. However the most important findings are the horizontal fractures of the posterior elements. The vertebral body fractures show hardly any compression. At first glance this looks just like another burst fracture. In the absence of a neurologic deficit, PLC integrity should be confirmed at MR imaging, especially if conservative management of a clasificaciom fracture is planned 3.
Minimal anterior displacement of the upper vertebral body. In both cases the patient is a surgical candidate. There is not much else happening here. Retropulsion of a fragment is the typical feature of a burst xlasificacion and fracturqs it clearly from a simple compression fracture.
Vertebral body translation or rotation.
Clasigicacion 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. This means that a patient can be treated non-surgically.
Distraction is the result of displacement in the vertical plane. On the right with kyphosis. Now when you look carefully at the lateral view, you will notice that the facets are separated. In this case there is severe compression of the vertebral body.
The Radiology Assistant : Spine injury – TLICS Classification
The morphology is of a vertebral fracture with retropulsion of a fragment, i. One of the fractures is a typical avulsion. Patients with a rigid spine are more at risk for translation or distraction. Rigid spine Patients with a rigid spine such as in ankylosing spondylitis, DISH and rheumatoid arthritis are more susceptible to spinal fractures, even after minimal trauma 6. frafturas
The posterior cortex of the vertebral body has to be intact and this feature differentiates a simple compression fracture from the more severe burst fracture. The MRI shows exactly the same things. One of the spinous processes is in two pieces and the two pieces are widely separated. Notice the rigid spine and how easily this major injury can be overlooked. Neurological status The third category is the neurological status as determined by the neurologist or spine surgeon.
Patients with a rigid spine such as in ankylosing spondylitis, DISH and rheumatoid arthritis are more susceptible to spinal fractures, even after minimal trauma 6. 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. Look at the images.

You have to look at the thin slices to detect such a subtle fracture. A total of more than 4 clasificscion indicates surgical treatment. TLICS score based on imaging is 7 points.
