Mesenchymal stem cells and thermal annular procedures for discogenic pain: a systematic review with pooled analysis.

Aim: Compare the effectiveness of mesenchymal stem cell injection therapies (MSC) and thermal annular procedures for the treatment of discogenic lower back pain. Materials & methods: A systematic review was performed following PRISMA 2020 guidelines. Pooled analysis was performed using patients' pain scores at baseline and at 12 months post-intervention. Results: Effect sizes based on change in pain score from baseline to 12 month follow-up revealed clinically significant improvement in pain score across all interventions. Conclusion: Minimally invasive interventions provide meaningful relief in discogenic back pain, with results suggesting promise for MSC injection therapies as a treatment model.
