Microendoscopic discectomy (MED) offers a safe and effective treatment for herniated lumbar disc disease, leading to shorter hospital stays and quicker return to work for most patients.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Spine Surgery

Background:

  • Microendoscopic discectomy (MED) was developed in 1997 for herniated lumbar disc disease.
  • It has been adopted by over 500 institutions worldwide.

Purpose of the Study:

  • To discuss the technical aspects of the MED procedure.
  • To present outcomes from a consecutive case series.

Main Methods:

  • 150 patients underwent MED using a muscle-splitting approach with tubular dilators and a tubular retractor.
  • Endoscopic microdiscectomy was performed with surgeon visualization via video monitor.

Main Results:

  • 77% excellent, 17% good outcomes (modified MacNab criteria).
  • Average hospital stay: 7.7 hours; average return to work: 17 days.

  • 5% complication rate (dural tears), decreasing with experience.

    • Conclusions:

    • MED is a safe and effective treatment for lumbar herniated discs.
    • The procedure offers benefits of reduced hospital stay and faster return to work.
    • A learning curve is associated with mastering the MED technique.
