Percutaneous laser disc decompression (PLDD) effectively treats spinal stenosis caused by bulging discs. This minimally invasive procedure offers significant pain relief for patients, comparing favorably to open surgery.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Procedures
  • Pain Management

Background:

  • Spinal stenosis, common in older adults, causes debilitating low back and radicular pain.
  • The condition often resists conservative treatments and traditional open surgery.
  • Percutaneous laser disc decompression (PLDD) offers a minimally invasive alternative for disc protrusions.

Purpose of the Study:

  • To evaluate the efficacy of PLDD for spinal stenosis with bulging or protruding discs.
  • To assess pain reduction as the primary outcome measure.

Main Methods:

  • An unblinded study involving 35 patients with MRI-confirmed lumbar spinal stenosis and disc protrusions.
  • Outpatient treatment using PLDD.
  • Pain was rated on a 0-10 scale immediately after treatment, and at 1 day, 4 weeks, and 5-49 months post-procedure.

Main Results:

  • Excellent pain relief (0-2 score) was achieved in 69% of patients.
  • Good pain relief (3-5 score) was observed in 9% of patients.
  • Sustained pain relief was noted through all follow-up periods.

Conclusions:

  • PLDD is an effective treatment for lumbar spinal stenosis attributed to bulging or protruding discs.
  • The procedure demonstrates favorable outcomes compared to open surgical interventions.
