What is a consequence of disc injury or degeneration?

A consequence of disc injury or degeneration often involves the nucleus pulposus, which is the gel-like center of intervertebral discs. Over time, with injury or degeneration, this central structure can suffer damage and may fragment. This fragmentation can lead to several complications, including increased pressure on nearby spinal nerves, potential herniation, and the overall instability of the spinal column. This aligns with the understanding of how disc injuries affect not just the disc itself but also the surrounding vertebral structures and overall spinal health.

In contrast, increased joint flexibility and enhanced nutrient diffusion are typically not associated with disc injury or degeneration. Instead, disc degeneration often leads to reduced flexibility and impaired nutrient flow due to diminished disc health. Additionally, while ligament strength is crucial for spinal stability, disc degeneration tends to weaken overall structural support rather than strengthen it. This context highlights why the fragmentation of the nucleus pulposus is a critical consequence of such injuries or degeneration.
