Comparing Two Surgical Methods for Treating Multilevel Lumbar Spinal Stenosis Decompressive Laminectomy Alone Versus Laminectomy With Transpedicular Screw Fixation

What this Trial Is About

Lumbar spinal stenosis is a condition where the spinal canal narrows, causing back pain, numbness, leg pain, and difficulty walking. This research aims to compare two surgical approaches for treating lumbar spinal stenosis decompressive laminectomy alone and decompressive laminectomy combined with transpedicular screw fixation. The study seeks to find which surgery offers better pain relief, improved function, fewer complications, and greater spinal stability after surgery. Participants aged 30 to 60 years with MRI-confirmed multilevel lumbar spinal stenosis who have not improved after six weeks of conservative treatment will be randomly assigned to one of two groups. One group will have decompressive laminectomy alone, which involves removing the vertebral lamina to relieve pressure on the spinal canal. The other group will have decompressive laminectomy with additional spinal stabilization using transpedicular screw fixation to prevent instability and promote fusion. During the study, researchers will measure pain levels using the Visual Analog Scale VAS at the start, day 7, and three months after surgery, and functional status using the Oswestry Disability Index ODI at the start and three months post-surgery. Postoperative X-rays will assess spinal stability and bone fusion. Other data collected include operative time, complications, and hospital stay length. The total study will last six months, with participants closely monitored throughout.
