Lumbar disc herniation: Natural history, role of physical examination, timing of surgery, treatment options and conflicts of interests

Introduction: Indication for surgery in lumbar disc herniation (LDH) varies widely depending on the geographical area. Development: A literature review is presented on the natural history, role of physical examination, timing of surgery, evidence-based treatment, and conflicts of interests in LDH. Surgery is shown to provide significant faster relief of pain compared to conservative therapy, although the effect fades after a year. There is no treatment modality better than the rest in terms of pain control and neurological recovery, nor is there a surgical t technique clearly superior to simple discectomy. The lack of sound scientific evidence on the surgical indication may contribute to its great geographical variability. Conclusions: Since LDH has a favourable natural history, neuroimaging and surgery should not be considered until after a 6-week period. It is necessary to specify and respect the surgical indications for LDH, avoiding conflicts of interests. (c) 2016 Sociedad Espanola de Neurocirugia. Published by Elsevier Espana, S.L.U.
