This model of two lumbar vertebrae in about double life size has the opportunity to demonstrate a lateral intervertebral disc hernia. If the two vertebrae are pressed together, the inner core of the disc will be protruding to the outside, forming a hernia. The protruding hernia shows graphically the pressure which affects the spinal nerve. With this helpful tool you can demonstrate fast and easily what happens when a patient suffers from a herniated disc. Because of the enlarged size it is easy to handle and also suitable for group teaching.
