Summary

Percutaneous lumbar disc decompression (PLDD) using the Dekompressor device offers long-term pain relief and improved function for patients with discogenic radicular pain. While follow-up was limited, results suggest favorable outcomes and patient satisfaction.

Area of Science:

  • Spine surgery
  • Minimally invasive procedures
  • Pain management

Background:

  • Limited research exists on the long-term effectiveness of percutaneous lumbar disc decompression (PLDD) using the Dekompressor device for persistent discogenic radicular pain.
  • Conservative treatments often fail for this patient group, necessitating alternative interventions.

Purpose of the Study:

  • To evaluate the long-term outcomes of Dekompressor PLDD in patients suffering from discogenic lumbosacral radicular pain.
  • To assess pain reduction, functional improvement, patient satisfaction, and the need for subsequent surgery.

Main Methods:

  • A prospective cohort study was conducted involving patients with discogenic lumbosacral radicular pain who underwent Dekompressor PLDD.
  • Pain (NRS) and disability (ODI) scores were recorded at 6 months and 1 year, with satisfaction and surgical rates assessed at 8 years.
  • Intention-to-treat analysis was employed to account for patient attrition.

Main Results:

  • At 1 year, over 40% of patients experienced significant pain reduction (>50% NRS) and functional improvement (>30% ODI).
  • Long-term follow-up at 8 years showed sustained, though reduced, efficacy with 29% experiencing pain relief and 26% functional improvement.
  • Among those followed at 8 years, 36% had undergone surgery, with a median satisfaction score of 4.

Conclusions:

  • Despite limitations due to patient loss to follow-up, Dekompressor PLDD appears to provide long-term benefits for leg pain and disability in discogenic radicular pain.
  • Favorable patient satisfaction was noted at the 8-year mark.
  • Further research with higher follow-up retention is required to definitively establish Dekompressor PLDD's role in potentially avoiding open spinal surgery.
