Comparative Efficacy of Percutaneous Laser Disc Decompression (PLDD) and Conservative Therapy for Lumbar Disc Herniation: A Retrospective, Observational, Single-Center Study

Background: Although percutaneous laser disc decompression (PLDD) has been proposed as an alternative to conventional surgery for lumbar disc herniation (LDH), we specifically propose it for patients with contained herniations where standard surgical intervention is not the first option. This study evaluates PLDD compared to conservative therapy as an early treatment alternative. Methods: This retrospective observational study compared PLDD to conservative treatment in adult patients with contained LDH. All patients underwent 3 months of standard conservative therapy. Those who remained dissatisfied according to the Visual Analog Scale (VAS) and/or Macnab criteria were then treated with PLDD. We analyzed outcomes from both treatment phases using the Wilcoxon signed-rank test and the Mann–Whitney U test. Results: 121 patients underwent outpatient evaluation for LDH and received an average of 90 days of conservative therapy. Of these 103 patients, dissatisfied with the outcomes of conservative treatment, subsequently underwent PLDD. Following conservative treatment, the average VAS score reduction was 4.1%. Six months after PLDD, the VAS scores demonstrated a significant reduction, with an average decrease of 30% (p < 0.0001). In terms of functional outcomes assessed by the Macnab criteria, 39.8% of patients treated with PLDD achieved ‘Excellent’ or ‘Good’ outcomes, compared to only 11.4% after conservative treatment. Conclusions: PLDD appears to be a viable alternative to conservative therapy for this subgroup of patients with contained LDH. It may be beneficial to propose PLDD early in the therapeutic regimen to accelerate short term clinical improvement. Further studies are required to evaluate the long term efficacy of this treatment approach.
