Model of i.a. spinal stenosis and herniated disc with replaceable discs

Anatomically, the model shows 2 lumbar vertebrae and therefore the two most important joint types in the spinal column, which are the symphyses (disci/band discs) between the vertebral bodies and the facet joints, which are sliding joints between the vertebrae's pivots. Overall, the bone quality is very good, and therefore, for example, knots and depressions in the bone tissue are clearly visible. Furthermore, spinal nerves are seen.



The model also includes different discs, which allow for the demonstration of different types of disc herniation. Spinal stenosis and spondylolysis may also be demonstrated.

In terms of movement, this model is not flexible. It cannot be moved at all and therefore cannot be used to demonstrate the movements of the spine.



The model, on the other hand, can be separated into 10 parts, and the different discs can be inserted between the vertebrae. In this way, the various disorders and their consequences can be demonstrated.

Clinically, as mentioned, this model has been developed for understanding spinal stenosis, various types of disc herniation and spondylolysis.



However, the model can also be used to understand other disorders such as spondylosis, osteoarthritis, fractures etc.
