BACKGROUND AND OBJECTIVES: Most adults have several low back pain episodes during their lives. Ozone therapy is a minimally invasive method able to promote analgesia for most patients, with few reports of complications. This study aimed at reviewing the literature on the use of ozone therapy to treat low back pain and lumbosciatic pain. CONTENTS: Virtual Health Library was searched using the following keywords: ozone, therapy, pain, back, lumbodynia. Search sources included: LILACS, Medline, Cochrane, Pubmed, Ibecs and scientific journals, looking for articles originally published in English, Spanish and Portuguese in recent years. Fifty-four articles were selected. Two were randomized multicenter studies, four were systematic reviews, one was a meta-analysis with more than 8 thousand patients from different centers, one was a national Italian consensus, many were double-blind studies, some had control groups and many were observational studies. The level of evidence to support a stronger recommendation is still low (II-3 for intradiscal administration and II-1 for paravertebral or intraforaminal muscular administration), however this scenario seems to be dynamic with a trend toward the indication of ozone therapy. CONCLUSION: Ozone therapy was effective to treat low back pain with our without sciatic pain, being associated to few adverse events.
