To the Editor: The randomized controlled trial by Dr Arts and colleagues1 compared 2 methods of treatment for sciatica (tubular and conventional microdiskectomy) and showed significantly better results for the latter in the primary outcome of functional assessment on the Ronald-Morris Disability Questionnaire (RDQ) at 1 year and better secondary outcomes on the visual analog scale for leg pain and back pain and patient's self-report of recovery. Although the authors could not determine the reasons for these results, they noted that the participating neurosurgeons had broad experience in both techniques.
