There are a total of 23 intervertebral discs in the human spine. These discs are located between the vertebrae in the cervical, thoracic, and lumbar regions, with no discs present in the sacral and coccygeal regions. Specifically, there are 7 cervical, 12 thoracic, and 5 lumbar discs. The discs serve as shock absorbers and allow for movement between the vertebrae.
An intervertebral disk in which the nucleus pulposus has protruded through surrounding fibrocartilage. This occurs most frequently in the lower lumbar region.

It is the removal of an intervertebral disk
The intervertebral disc has undergone compression.
Artificial disk replacement is a surgery used to relieve back pain. Disk replacement surgery replaces an intervertebral disk with a mechanical device.
The surgical removal of a portion of an intervertebral disk
The strong fibrous tissue outer periphery of the intervertebral disk is called the annulus fibrosus.

Moderate narrowing of the L5-S1 intervertebral disk space indicates a reduction in the height of the intervertebral disk between the fifth lumbar vertebra and the first sacral vertebra, often associated with degenerative changes. The vacuum disk phenomenon refers to the presence of gas (usually nitrogen) within the disk space, which appears on imaging as dark areas and is a sign of disk degeneration. This combination can result in lower back pain and may affect spinal stability. It is typically seen in older patients or those with a history of spinal issues.
The word disk, as it applies to the back, refers to elastic tissue that sits between the vertebrae. These disks absorb shock during movement.
Cylindrical elastic-like gel pads
