Why might low back pain commonly arise?

Low back pain can arise from a variety of sources, and one common issue involves intervertebral disc (IVD) problems, specifically related to the annulus fibrosus and posterior longitudinal ligament (PLL). The intervertebral discs act as shock absorbers between the vertebrae, and any dysfunction or degeneration in these structures can lead to pain.

The annulus fibrosus is the tough outer layer of the disc that helps maintain its shape and integrity. When this structure becomes damaged or herniated, it can cause irritation of nearby nerves, resulting in pain. Additionally, the posterior longitudinal ligament, which runs along the back of the vertebrae, supports the spine and protects the spinal cord. Any issues with this ligament, such as inflammation or tears, can contribute to low back pain by putting pressure on spinal structures or leading to instability.

Considering this, dysfunctions of the intervertebral discs are significant contributors to low back pain. They can lead to complications that affect mobility and may require comprehensive treatment approaches.
