Summary

Laser decompression surgery using Neodymium-YAG and Potassium Titanyl Phosphate lasers effectively reduced patient pain for symptomatic contained bulging discs. Both laser types demonstrated similar success rates, validating laser surgery for percutaneous disc nucleotomy.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Surgery
  • Spinal Surgery

Background:

  • Percutaneous laser disc decompression offers a minimally invasive alternative for treating symptomatic contained bulging discs.
  • The Neodymium-YAG (Nd:YAG) and Potassium Titanyl Phosphate (KTP) lasers are utilized in spinal procedures.
  • Early adoption of laser technology in spinal surgery required evaluation of efficacy and safety.

Purpose of the Study:

  • To evaluate the efficacy and safety of laser decompression for symptomatic contained bulging discs.
  • To compare the outcomes of Nd:YAG laser treatment with KTP laser treatment.
  • To assess pain reduction and neurological changes following laser-assisted percutaneous disc nucleotomy.

Main Methods:

  • A case study involving 333 patients treated with Nd:YAG laser (1064-nm wavelength).
  • Treatment of 117 patients with KTP laser (532-nm wavelength), with detailed surgical techniques presented.
  • Follow-up statistics including 1-year and 2-year outcomes for KTP laser patients and a subset of Nd:YAG patients.

Main Results:

  • Statistically significant reduction in average patient pain documented by disc level and follow-up duration.
  • No statistically significant variation in average specific neurologic findings (e.g., reflexes, strength) by disc level or follow-up duration.
  • High success rates: 72% at 2-year follow-up for KTP laser and 70% for Nd:YAG laser, with no major complications.

Conclusions:

  • Laser decompression surgery using both Nd:YAG and KTP lasers is a safe and effective treatment for symptomatic contained bulging discs.
  • Percutaneous laser disc nucleotomy provides a valid surgical option with encouraging long-term pain relief.
  • The study substantiates the role of laser technology in advancing minimally invasive spinal interventions.
