What Is an Intervertebral Disc?
An Intervertebral Disc is a flexible pad between neighboring vertebrae in the spine. Each disc has a softer inner center and a firm outer ring. Together, these parts help the spine move, absorb pressure, and keep the vertebrae spaced apart during everyday activities.

Key Takeaways About Intervertebral Disc
- Each disc has a soft center and a firm outer ring.
- Disc movement helps maintain space between neighboring vertebrae.
- A disc is not the same structure as a vertebra.
How Intervertebral Disc Works
An Intervertebral Disc works as a cushion between two spinal bones. Its soft inner center spreads pressure, while the tougher outer ring helps contain that center. This design supports bending, turning, and other normal spinal motion.

Disc height and shape affect the space between nearby vertebrae. The spine also includes nerve roots, which pass near some discs. During an assessment, a clinician considers the disc area along with posture, movement, and reported symptoms. Spinal decompression therapy focuses on controlled spinal positioning and loading around the affected area.
From the Advanced Injury Care Clinic team
When we assess an intervertebral disc during spinal decompression therapy, we consider the nearby spinal joints, movement patterns, and reported symptoms. Our team uses that information to guide positioning and monitor how the body responds during care.
Intervertebral Disc in Practice: A Real-World Example
A person with back discomfort may have symptoms near a disc in the lower spine. During spinal decompression therapy, the clinician selects positioning that places controlled attention on the involved spinal area.
