Improvement of Low Back Pain After Decompression in Patients with Degenerative Spinal Canal Stenosis

Degenerative lumbar spine disease is a common indication for lumbar decompression surgery, especially in elderly patients. Moreover, Clinical studies prove that decompression is superior to conservative treatment with more favorable outcomes . Surgical options for decompressing the lumbar spine vary from minimally invasive disc decompression to open laminectomy and foraminotomy. The surgery aims to improve the quality of life in appropriately selected patients , in the form of improvement of walking distance, lower limbs pain, and other symptoms of spinal compression. Few papers assessed LBP improvement after lumbar decompression surgery . The common practice that patients with degenerative canal stenosis and low back pain should undergo fusion surgery is not evidence based. In this study the investigators aim to assess the improvement of clinical symptoms, especially low back pain and lower limbs pain in patients with degenerative lumbar spine disease after undergoing lumbar decompression surgery.
