A Systematic Review of Treatment Guidelines for Lumbar Disc Herniation.

Various treatments have been developed for treating herniated lumbar discs (HLD), which have been examined by professional associations when composing clinical guidelines that provide structured approaches to treating HLD. This paper aims to gather recent guidelines and summarize their conclusions on nonsurgical and surgical treatment options. PubMed, Web of Science, Scopus, Guidelines International Network, Turning Research into Practice databases, and websites of medical societies were searched for clinical guidelines of HLD. Full-text guidelines published by a professional association in English relevant to HLD were included. Comparisons among guidelines were made based on the treatments evaluated, and recommendation grades were recorded when provided by the guidelines. A total of 12 guidelines were included, with 4 by non-United States (US) or international associations, 3 by US pain societies, 2 by surgical societies, 2 by government agencies, and 1 by a multidisciplinary medical society. Treatments assessed included surgical, invasive nonsurgical, and noninvasive nonsurgical interventions. Three guidelines did not include surgical treatments, and 2 guidelines did not include nonsurgical therapies. Recommendation criteria varied among guidelines due to differences in the intended audience. HLD can be treated with various modalities with specific therapies offering better pain relief. Despite inconsistency in the recommendation grades of most treatments, established surgical techniques and epidural injections were reported with higher confidence in recommendation estimates, while inadequate supporting evidence was shown for noninvasive therapies except cognitive behavioral therapy. Future studies could incorporate and comment on some of the newer methods of treating HLD.
