Transparent and flexible model of the lumbar spine, sacrum and coccyx with nerves

Anatomically, the model shows the two lower thoracic vertebrae T11 and T12 as well as the 5 lumbar vertebrae in the lower back, the sacrum with the coccyx molded into one. Therefore, the model shows the two most important joint types in the spinal column, which are the symphyses (disci/discs) between the vertebral bodies and the facet joints which are sliding joints between the articular facets of the vertebrae. Overall, the bone quality is good, and therefore, for example, larger protrusions are seen in the bone tissue.



As for nerves, the model shows the lumbar, sacral and coccygeal spinal nerves (with both anterior and posterior radix).

The model is flexible in terms of movement. The human spine has a high degree of mobility in the lumbar region (which is lordotic). This model can be used to demonstrate the most important movements in the lumbar region, which are flexion-extension, lateral flexion and rotation.



It is possible to see the course of the nerves through the sacral canal as well as the Y-shaped canals in its lateral wall.

Clinically speaking, this model is ideal for understanding disorders such as disc herniation, scoliosis, root affection, back pain, spondylosis, spinal stenosis and osteoarthritis (arthrosis).



It can also be used to understand fractures etc
