BACKGROUND: Several cell-based therapies have been proposed in recent years the management of low back pain, including the injection of medicinal signaling cells or mesenchymal stem cells (MSCs) and platelet-rich plasma (PRP). However, there is only emerging clinical evidence to support their use at this time. OBJECTIVE: To assess the effectiveness of MSCs or PRP injections in the treatment of low back and lower extremity pain. STUDY DESIGN: A systematic review and metaanalysis of the effectiveness of PRP and MSCs injections in managing low back and lower extremity pain. DATA SOURCES: PubMed, Cochrane Library, US National Guideline Clearinghouse, prior systematic reviews, and reference lists. The literature search was performed from 1966 through June 2018. STUDY SELECTION: Randomized trials, observational studies, and case reports of injections of biologics into the disc, epidural space, facet joints, or sacroiliac joints. DATA EXTRACTION: Data extraction and methodological quality assessment were performed utilizing Cochrane review methodologic quality assessment and Interventional Pain Management Techniques - Quality Appraisal of Reliability and Risk of Bias Assessment (IPM-QRB) and Interventional Pain Management Techniques - Quality Appraisal of Reliability and Risk of Bias Assessment for Nonrandomized Studies (IPM-QRBNR). The evidence was summarized utilizing principles of best evidence synthesis on a scale of 1 to 5. DATA SYNTHESIS: Twenty-one injection studies met inclu...
