Intervertebral disc replacement

1. What is an intervertebral disc?

The spine consists of vertebrae that are connected to each other by intervertebral discs. These intervertebral discs act as shock absorbers and enable movement and stability of the spine.

2. Why might an intervertebral disc be replaced?

If surgery is performed on the cervical spine from the front, the intervertebral disc is removed. This must then be replaced. This is possible with either a cage or an artificial disc. The cage results in a stiffening, while the artificial disc allows the cervical spine to remain mobile.

3. How does an artificial intervertebral disc work?

The artificial disc often consists of 2 metal plates that are connected to each other by a polyethylene core. This enables a more natural movement and in certain cases also shock absorption.

4. Advantages

Compared to traditional fusion surgery, in which two vertebrae are fused together, the artificial disc allows the mobility and flexibility of the spine to be maintained. This can help to relieve the adjacent segments and prevent so-called subsequent degeneration.
It is important to emphasize that the decision for an artificial disc should be made on an individual basis and must be made in close consultation with the attending physician. In certain cases, this intervention can be a promising option for relieving pain and maintaining or restoring the functionality of the spine.
