ⓘ Spinal disc herniation

Spinal disc herniation is an injury to the cushioning and connective tissue between vertebrae, usually caused by excessive strain or trauma to the spine. It may result in back pain, pain or sensation in different parts of the body, and physical disability. The most conclusive diagnostic tool for disc herniation is MRI, and treatment may range from painkillers to surgery. Protection from disc herniation is best provided by core strength and an awareness of body mechanics including posture.

When a tear in the external, fibrous ring of an intervertebral disc allows the soft, Central part to bulge out of the damaged outer ring, disk, called a hernia.

Disc herniation is often associated with age-related degeneration of the outer ring, known as annulus fibrous ring, but is usually caused by trauma or straining, lifting or twisting. Tears are almost always postero-lateral in the back of the hand due to the presence of posterior longitudinal ligament in the spinal canal. The gap in the disk ring may result in the release of chemicals that cause inflammation, which can lead to severe pain even in the absence of compression of nerve roots.

A herniated disk usually represents a further development of previously existing disc protrusion, in which the outer layers of the annulus fibrosus anulus remains intact, but can bulge when the disc is under pressure. In contrast to a herniation, none of the Central part of the shoots in the outer layers. The smallest hernias heal in a few weeks. Anti-inflammatory treatment for pain associated with disc herniation, protrusion, bulge, or disc tear is usually effective. Severe hernias may not heal on their own and may require surgical intervention.

The condition may be called the intervertebral disc, but this term is not accurate since the intervertebral discs are firmly attached between the vertebrae and does not "slip" on the spot.
