Anterior longitudinal ligament

The anterior longitudinal ligament is a ligament that runs down the anterior surface of the spine. It traverses all of the vertebral bodies and intervertebral discs on their ventral side.[1]

Structure

The ligament is thick and slightly more narrow over the vertebral bodies and thinner but slightly wider over the intervertebral discs. This effect is much less pronounced than that seen in the posterior longitudinal ligament. The ligament actually has three layers: superficial, intermediate and deep. The superficial layer traverses 3 – 4 vertebrae, the intermediate layer covers 2 – 3 and the deep layer is only between individual vertebrae.
