Vertebral Simulator with Herniated Disc

FINAL SALE: No returns will be accepted for this item.

An essential Simulator for Work Prevention physiotherapy, Occupational Health, Osteopaths, Chiropractors, Sports Injury, GP's and all Medical and Educational applications.

This innovative vertebral simulator model shows the injured mechanism of a herniated disc. The vertebral simulator model demonstrates how the intervertebral disc prolapses when flexing the vertebras, reproducing what happens in real life when we bend or twist our trunk.

Since vertebral disorders are now widespread, therapists should have this model to make people aware of the importance of gentle movements and behaviors for the spinal column. This vertebral simulator model will be of great assistance in medicine, physiotherapy, medical surgeries and clinics, work risk prevention, ergonomics, physical education and otter fields.

The vertebral simulator model consists of two vertebras with an elastic intervertebral disc, spinal cord and nerves. Ideal for Osha training.

Straight back: vertical pressure
In their function as shock absorbers, intervertebral discs are constantly being compressed. If you press the simulator straight up and down, the pressure is the same throughout the disc and it becomes homogeneously deformed. Only if the disc was previously damaged, with injured ligaments, a small pressure might cause a protrusion.

Trunk torsion
Also a hernia may occur when you turn the vertebras. When the ligaments of the disc are turned, the pressure inside the disc becomes very strong and a protrusion occurs in the weakness area. That movement simulates a disc torsion in a turn of the spine.

Trunk flexion
However, if you press the front part of the simulator, the nucleus of the disc moves to the other side and a protrusion or a slipped disc is formed. This movement also may simulate sciatica. The picture shows the formation of a posterolateral hernia, one of the most usual.

Combined movement: flexion and torsion
Finally, if you press the front part and turn the vertebras at the same time, a big hernia is formed. This is a very risky movement, especially for people that usually suffer from back pain.
