Summary
Microdecompression offers superior results for lumbar spinal stenosis compared to open laminectomy, showing less back pain and blood loss. Both techniques effectively treat leg pain and disability.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Degenerative Spine Disease
Background:
- Lumbar spinal stenosis (LSS) is commonly caused by degenerative aging.
- Open laminectomy was the traditional treatment for LSS.
- Minimally invasive techniques are increasingly preferred for LSS decompression.
Purpose of the Study:
- Compare microdecompression with open laminectomy and posterior stabilization.
- Evaluate outcomes for symptomatic multilevel LSS refractory to conservative care.
Main Methods:
- Randomized controlled trial (Jan 2016-Oct 2018) with 100 patients.
- Group A: 50 patients underwent microdecompression.
- Group B: 50 patients underwent open wide laminectomy and posterior stabilization.
- One-year follow-up using Oswestry Disability Index (ODI) and Visual Analogue Score (VAS).
Main Results:
- Both groups showed significant Oswestry Disability Index improvement.
- Microdecompression group had better outcomes for back pain due to less tissue injury.
- Both techniques significantly improved radicular leg pain postoperatively.
Conclusions:
- Microdecompression and open laminectomy with stabilization are effective for multilevel LSS.
- Microdecompression demonstrated superior outcomes regarding postoperative back pain, blood loss, and soft tissue dissection.
- Clinical trial registration: NCT04087694.
