Sidebar: Key Points

  • Effectiveness of microdiscectomy was assessed in lumbar disc herniation patients with 6 to 12 weeks of symptoms but no absolute indication for operation.

  • Discectomy seemed to be associated with a more rapid initial recovery.

  • Over the 2-year follow-up, there were no clinically significant differences between discectomy and conservative treatment in leg or back pain intensity, subjective disability, or health-related quality of life.

  • Spinal level of the herniation may be a factor of importance in modifying effectiveness of surgery.
