This model of the spine is very flexible and shows the vertebral artery, spinal nerves, neck bone (os occipitale), pelvis, hip joint and a herniated disc.

The model measures 78 cm in height. All the vertebrae are held together by a metal tube, which is typically only found in spines in a higher price range. Furthermore, an elastic system has been inserted in the upper neck vertebrae. The model is delivered together with a white metal stand on which it can be hung.

Anatomical features

Anatomically speaking, the model shows the entire vertebral column, which consists of a neck part, a chest part, a lumbar part, a pelvic part and the coccyx. The neck bone is also included. Therefore, the model shows the two most important joint types in the spinal column, which are the symphyses (disci/band disks) between the vertebral bodies and the facet joints, which are sliding joints between the vertebrae's pivots. The lower neck joint and the sacrococcygeal joint are also seen. Since the neck bone is included on this model, the upper neck joint is also visible.

In addition, the model shows the pelvis in its entirety as a ring structure as well as both femoral heads with the femoral neck and part of the femur. Therefore, the model also shows the SI joint between the sacrum and the pubic bone, the symphysis between the pubic bones and the hip joint.

Furthermore, the model shows the vertebral artery, the 31 pairs of spinal nerves and a herniated disc in the lower back. Overall, the bone quality is very good, and therefore, for example, knots and depressions in the bone tissue are clearly visible.

Product flexibility

In terms of movement, the model is very flexible. The mobility of the human spine is greatest in the cervical and lumbar regions (which are lordotic), while the thoracic region (which is kyphotic) is less mobile. This model can be used to demonstrate the most important movements of the spine, which are flexion-extension, lateral flexion and rotation in the neck and lumbar region.

The above-mentioned metal tube ensures both that you can detach the disc from the vertebrae without it falling apart, and that stability is felt when moving the spine.

The neck bone (os occipitale), upper cervical vertebra (atlas) and second upper cervical vertebra (axis) are gathered together with elastic string, which causes a special elastic effect, where the vertebrae both follow each other during movement and come together again in a natural way. You can thus demonstrate the most important movements in the neck joints, which are the nodding and rocking of the head, which takes place in the upper neck joint and the shaking of the head, which takes place in the lower neck joint.

In the hip joints, the head of the femur is held firmly in the socket via elastic. Therefore, different movements of the hip joint, such as abduction and rotation, can be demonstrated. The femoral head can also be completely removed.

Clinical features

Clinically, this model is ideal for understanding disc herniation, root involvement and spondylolisthesis. It can also be used to understand disorders such as back pain, scoliosis, spondylosis, spinal stenosis and osteoarthritis.

The model can of course also be used to understand fractures, a. vertebralis dissection and many different disorders related to the hip joint and the pelvis.
