Brief 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.

Outcome Measures
Primary Outcomes (1)
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.
Baseline and 3 months after surgery
Study Arms (2)
Decompressive Laminectomy Only
ACTIVE COMPARATORSurgical decompressive laminectomy performed without instrumented fixation in patients with multilevel lumbar spinal stenosis.
Laminectomy With Transpedicular Screw Fixation
EXPERIMENTALSurgical decompressive laminectomy combined with transpedicular screw fixation to provide additional spinal stability in patients with multilevel lumbar spinal stenosis.
Interventions
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.
Surgical removal of the vertebral lamina to decompress the spinal canal in patients with multilevel lumbar spinal stenosis. No instrumentation or fixation is applied.
