Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Spinal Surgery

Background:

  • Lumbar spinal stenosis is a leading cause of disability in older adults, frequently requiring surgical intervention.
  • Instability is not a prerequisite for surgical intervention in lumbar spinal stenosis.

Purpose of the Study:

  • To assess the clinical effectiveness of interlaminar stabilization after decompressive laminectomy.
  • To evaluate outcomes in patients with lumbar stenosis but without instability.

Main Methods:

  • Twenty patients with lumbar stenosis underwent decompressive laminectomy and interlaminar stabilization.
  • Clinical outcomes were measured using the Visual Analog Scale (VAS) for pain and Oswestry Disability Index (ODI) for function.
  • Outcomes were compared preoperatively and at 2-month, 6-month, and 1-year postoperative visits.

Main Results:

  • Significant improvements were observed in low back pain (VAS: 8.8 to ~3.9) and lower extremity pain (VAS: 9.0 to ~2.5).
  • Oswestry Disability Index (ODI) scores improved significantly from 66.6 to ~24.
  • No significant differences in VAS or ODI scores were found between the 2-month, 6-month, and 1-year follow-up points.

Conclusions:

  • Decompressive laminectomy combined with interlaminar stabilization is a viable surgical option for lumbar spinal stenosis without instability.
  • This procedure leads to significant improvements in pain and functional disability for affected patients.
