Moderate intervertebral disc space narrowing at the L2-L3 level is most characteristic of degenerative disc disease. This condition involves the gradual breakdown of the intervertebral discs, which can lead to a decrease in disc height and changes in the structure of the disc. As the discs degenerate, they lose their hydration and elasticity, resulting in narrowing of the disc space and potentially causing associated symptoms, such as pain and reduced mobility.

In contrast, infectious spondylitis typically involves inflammation due to infection, which can lead to changes in vertebral bodies rather than isolated disc narrowing. Identifying the characteristics of degenerative disc disease is critical for understanding the differentiation of these conditions when interpreting radiographic findings.
