Is this trial a fit for you?

Likely a good fit

Adults with chronic low back pain due to lumbar disc degeneration or stenosis who have MRI findings and are candidates for or undergoing posterior lumbar interbody fusion or lumbar discectomy.

Probably not a fit

Individuals not undergoing disc-related surgery or without measurable periostin expression or Pfirrmann grades may not benefit from the findings.

What this trial studies

This observational study examines the relationship between periostin expression in the intervertebral disc and Pfirrmann grading of disc degeneration in adults with chronic low back pain due to lumbar disc pathology. Participants are evaluated for lumbar conditions such as disc herniation or canal stenosis and undergo imaging and tissue assessment as available. The study uses surgical samples or imaging-based proxies to explore correlations with degeneration severity, without assigning a therapeutic intervention. No active treatment is tested; data collection focuses on understanding biological markers and imaging findings. Safety considerations align with standard care for participants undergoing routine procedures like posterior lumbar interbody fusion or lumbar discectomy.

Why it matters

Potential benefit: If successful, it could improve understanding of disc degeneration and guide future biomarker-driven approaches to treatment.

How similar studies have gone: Other studies have explored periostin and disc pathology with varying results, but this direct correlation study is relatively novel in this population.
