INTERVENTIONAL
Conditions
Summary
Lumbar spinal stenosis is a condition where the spinal canal becomes narrowed and can cause symptoms such as back pain, numbness, leg pain, and difficulty walking. Surgery is often considered when symptoms do not improve with medical treatment. This study will compare two types of surgery used to treat lumbar spinal stenosis: decompressive laminectomy alone and decompressive laminectomy with transpedicular screw fixation. Patients will be randomly assigned to one of the two surgical options. The purpose of this study is to determine which approach provides better pain relief, improved function, fewer complications, and better spinal stability after surgery.
Eligibility
Inclusion Criteria5

- Multilevel disc herniation
- Degenerative disc disease with Pfirrmann grade 3-5 on T2-weighted MRI
- Failure of at least six weeks of conservative treatment
Exclusion Criteria5
- Previous history of lumbar spine surgery

Interventions
Surgical removal of the vertebral lamina to decompress the spinal canal in patients with multilevel lumbar spinal stenosis. No instrumentation or fixation is applied.
Surgical decompression via laminectomy combined with spinal stabilization using transpedicular pedicle screws for multilevel lumbar spinal stenosis to prevent postoperative instability and provide bony fusion.
