This spine model consists of 3 cervical vertebrae. The following characteristics must be highlighted (read more about the characteristics in the text below):
- Reduced curvature (lordosis) to show how this makes the facet joints uneven
- Degenerative changes such as thickened corpse. flavum, osteophytosis and disc herniation
- An exceptional range of motion in the joints, which includes rotation
- Realistic tissue casting
Both in terms of size and weight, the model corresponds to 3 cervical vertebrae in an adult person. The model is not designed to be disassembled. It is possible to purchase a stand.
NB: This model is part of our unique series of dynamic and innovative spine models. The models are handmade in Canada, cast after human vertebrae and can demonstrate all the movements in the joints of the back. The materials are extremely lifelike in very high quality with components from the USA (and therefore not China etc.).
The models are developed with a focus on dynamics, interaction and simplicity in their use. The purpose is that the professional with the spinal joint model in hand can accurately and quickly explain the mechanisms of degenerative changes in the spine as well as their relationship to pain, function and the biomechanics of the spine. Furthermore, the models are developed to be able to withstand active and repeated use.
Anatomical features
Anatomical features
Anatomically, the model shows 3 cervical vertebrae (C5-C6-C7) 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. In the vertebral canal, bodies are seen. flavum.
Overall, the bone quality is extremely good, and therefore, for example, knots and depressions in the bone tissue are clearly visible.
Degenerative changes on the model include osteophytosis (marginal enlargement), narrowing of the vertebral canal with thickened body. flavum as well as reduced curvature (lordosis/backbending) to show how this makes the facet joints uneven. Furthermore, a visible disc herniation can be demonstrated between C6 and C7 - read more below.

Product flexibility
In terms of movement, the model is in a special class, just like the other models in this unique series of dynamic spine models. The model's 2 types of joints (the disc and the facet joints) can be moved in different natural ways.
The discs can be compressed and the cervical vertebrae can be moved naturally (see the video among the images on the left). Both by compression (compression) and dynamic extension of the cervical vertebrae, you can realistically demonstrate a herniated disc between C6 and C7, where red material bulges out into the vertebral canal (centrally).
As the model consists of 3 cervical vertebrae, rotation in the cervical spine can also be demonstrated. Thereby, the "opening and closing" of the IVF (intervertebral foramen) can be demonstrated - for example in relation to learning about degenerative changes that can affect the neurovascular content of the opening.
Clinical features
Clinical features
Clinically, the model is developed for learning about degenerative changes that cause pain. The model is ideal for learning about disc herniation, spinal stenosis and osteoarthritis of the cervical vertebrae. Since rotation can be clearly demonstrated on this model, it is also ideal for learning about degenerative changes that can affect the neurovascular content of the intervertebral foramen.
It is also ideal for learning about the cascades of changes in the joints that cause altered mechanics and pain.
