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.
Age 30-60 years
Diagnosis of lumbar spinal stenosis based on MRI criteria (anteroposterior canal diameter <10-15 mm or cross-sectional area <75-145 mm²)
Multilevel disc herniation
Degenerative disc disease with Pfirrmann grade 3-5 on T2-weighted MRI
Previous history of lumbar spine surgery
Spinal malignancy
Congenital lumbar spinal stenosis, scoliosis, or kyphoscoliosis
Lumbar spondylolisthesis grade 3-5
Parallel
Decompressive Laminectomy
Procedure/SurgerySurgical removal of the vertebral lamina to decompress the spinal canal in patients with multilevel lumbar spinal stenosis. No instrumentation or fixation is applied.
Decompressive Laminectomy With Transpedicular Screw Fixation
Procedure/SurgerySurgical decompression via laminectomy combined with spinal stabilization using transpedicular pedicle screws for multilevel lumbar spinal stenosis to prevent postoperative instability and provide bony fusion.
Change in Oswestry Disability Index (ODI)
Functional disability will be assessed using the Oswestry Disability Index (ODI), recorded preoperatively and at 3-month follow-up to measure improvement in functional outcome.
