What does a decrease in pressure in the IVD with decompression promote?

A decrease in pressure in the intervertebral disc (IVD) with decompression promotes enhanced nutrition to the disc. This is based on the physiological principles of how the intervertebral discs function.

The intervertebral discs are avascular structures, meaning they lack a direct blood supply. Instead, they rely on nutrient diffusion from the surrounding vertebrae and periosteum. When decompression occurs, the reduced pressure within the disc creates a negative pressure environment that helps to draw in vital nutrients and fluids from the surrounding tissues, thereby supporting the health and hydration of the disc. This process not only facilitates nutrition but also aids in the removal of metabolic waste products from the disc, contributing to its overall function and longevity.

Understanding this principle highlights the significance of spinal decompression therapies in promoting disc health, which can be particularly important in managing disc degeneration and aiding recovery in patients with disc-related pathologies.
