Abstract

Background/Objectives: Radicular pain is a frequent pathology, and disc herniation is the commonest aetiology. A meta-analysis summarising international guidelines for radicular pain, published in 2021, showed that lumbar traction's place is still a topic of debate. In this study, our aim was to evaluate the effectiveness of lumbar tractions in treating radicular pain of discal origin in association with medical treatment versus medical treatment alone. We performed a randomised, controlled, interventional, prospective, superiority trial in Reims Hospital Rheumatology Unit. Methods: We included participants with radicular pain and concordant disc herniation with ambulatory treatment failure. Participants were randomised into two groups: medical group (analgesics, anti-inflammatories treatments, at least two epidural injections); tractions group with this medical treatment associated with lumbar tractions. The primary outcome was the difference in the proportion of participants experiencing a minimum of 25% improvement in radicular pain at one month follow-up between the two groups. Results: We included 424 participants: 211 in the tractions group and 213 in the medical group. We analysed 388 participants (194 in each group). We collected demographic and clinical data, lumbar and radicular Numeric Pain Scale at baseline, one and three months. A statistical difference was found for the primary outcome: 120/194 participants (62%) in tractions group and 98/194 participants (51%) in medical group (p = 0.024). Conclusions: To our knowledge, this is the first randomised and controlled study on this topic with these results. We can assert the superiority of lumbar tractions in association with medical treatment over medical treatment alone for radicular pain with concordant disc herniation.
