Laser-assisted percutaneous lumbar discectomy using KTP/532 laser shows promise for treating contained herniated nucleus pulposus (HNP). This minimally invasive technique may be a viable alternative to conventional discectomy in select patients.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Spine Surgery
  • Laser Technology in Medicine

Background:

  • Herniated nucleus pulposus (HNP) is a common cause of low back pain.
  • Conventional discectomy can be invasive with potential complications.
  • Percutaneous techniques offer less invasive alternatives.

Purpose of the Study:

  • To evaluate the efficacy and safety of laser-assisted percutaneous lumbar discectomy (LPLD) using KTP/532 laser.
  • To compare LPLD with other discectomy methods.

Main Methods:

  • An 18-month study involving 40 patients with contained HNP.
  • Laser-assisted percutaneous lumbar discectomy utilizing KTP/532 laser.
  • Access via an 18-gauge probe and dilating cannulas under fluoroscopic guidance.

Related Experiment Videos

  • Use of a 400 µm quartz fiber with specific laser power and exposure settings.

    • Main Results:

    • Two of six patients required open conventional L4-5 discectomy, possibly due to subligamentous disc location.
    • Four patients declined further surgery.
    • Early results suggest LPLD is a viable option for selected HNP cases.

    Conclusions:

    • Laser-assisted percutaneous lumbar discectomy with KTP laser is a promising alternative.
    • It may offer advantages over automated percutaneous discectomy and other techniques in specific patient selections.
