What It Is

The bones (vertebrae) forming the spine are cushioned by flat, round discs. When the discs are healthy, they act as shock absorbers for the spine and help to keep it flexible (AAOS, n.d.a). If a disc becomes damaged, its soft centre may bulge outwards or break through its tough outer layer, which is referred to as a slipped, prolapsed or herniated disc (NHS, 2024). A herniated disc can occur in any part of the spine, but it tends to be most common in the neck (cervical spine) and the lower back (lumbar spine). Seven vertebrae between the upper back and the head make up the cervical spine (AAOS, n.d.a).

Cervical Disc Herniation Anatomy

The spine is made up of the lower and upper back and the neck. Your spine is an upright row of bones stacked on top of each other, which is referred to as the vertebral column. Individual bones within the spine are referred to as vertebrae. The vertebral column begins underneath the skull and runs all the way down to the buttocks.

The front of each vertebra is a solid, round cylinder of bone. Between each pair of vertebrae is a disc, attached to the vertebra above and the vertebra below. Each disc has a tough, flexible outer ring and a soft, jelly-like centre (AAOS, n.d.a). Strong muscles and ligaments keep the vertebral column together. All of these structures work together to support and protect the spinal cord.

When a disc herniates, its jelly-like centre pushes out towards the spinal canal and can press on a nerve root. This can cause neck pain and pain, tingling, numbness or weakness in the shoulder, arm or hand (AAOS, n.d.a; NHS, 2024).

Causes of Cervical Disc Herniation

The most common cause is age-related wear and tear (degeneration) of the discs. In younger people, it is most often caused by a sudden injury (AAOS, n.d.a). A herniated disc often happens with lifting, pulling, bending or twisting movements (AAOS, n.d.a). Other contributing factors may include genetics (weak fibres in the disc can run in families) and trauma (such as a sports injury or road traffic accident).
