Abstract

Background: Lumbar canal stenosis is defined as a narrowing of any part of the lumbar spinal canal. Several surgical techniques for lumbar spine decompression have been described; but there is no agreement about the best method.
Aim of the work: To assess the outcome of the different approaches in the surgical management of degenerative lumbar canal stenosis.
Patients and methods: This randomized clinical trial had been conducted. In this study; fifty patients with lumbar canal stenosis were divided into 3 groups; 20 patients subjected to laminectomy, 20 patients have undergone lamino-foramenotomy, and 10 patients received endoscopic lamino-foramenotomy. period of research varied from six-twelve months. The primary outcome was the improvement score of low back pain developed by the Japanese Orthopedic Association Lumbar Score, and the outcome was classified as excellent at more than 75.0% improved score; good, 50.0–75.0%; fair, 25.0–49.0%; and poor, 0.0–24.0% or less.
Results: There was no variation in improvement score at three and six months of different procedures. There was no variation in pain score at three and six months of different procedures. There is no variation in the operative outcome of different procedures.
Conclusion: Different approaches in the surgical management of single and multiple degenerative lumbar canal stenosis have similar effects. They are good surgery to treat degenerative lumbar canal stenosis, with reasonable outcomes.
