Endoscopic decompression surgery effectively treats lumbar nerve root compression, offering a less invasive option for severe radiculopathy. This minimally invasive approach provides significant pain relief for patients with intraforaminal and extraforaminal conditions.

Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Spinal Surgery

Background:

  • Intraforaminal and extraforaminal nerve root compression are distinct pathological conditions.
  • These conditions can cause severe radiculopathy, impacting patient quality of life.

Purpose of the Study:

  • To evaluate the outcomes of endoscopic decompression surgery.
  • Focus on treating intraforaminal and extraforaminal nerve root compression in the lumbar spine.

Main Methods:

  • Retrospective review of 17 consecutive patients undergoing endoscopic posterior decompression without fusion.
  • Procedures included lateral or translaminal decompression with or without discectomy.
  • Evaluated preoperative clinical findings, radiologic data (MRI, CT-discography), and postoperative JOA scores.

Published on: January 26, 2024

Main Results:

  • All patients presented with neurological deficits consistent with radiculopathy.
  • Imaging revealed nerve root compression due to disc protrusion or herniation in most cases.
  • Sixteen patients reported immediate postoperative pain relief, indicating surgical success.

Conclusions:

  • Endoscopic decompression is a suitable and less invasive surgical choice.
  • It offers an effective treatment for rare but severe cases of lumbar nerve root compression.
