Lumbar spinal stenosis is a condition caused by the narrowing of spaces within the lower spine, which can compress either the spinal cord or nerve roots. This pressure can lead to pain, numbness, or weakness—either locally or radiating down the legs—especially during activities that involve spinal extension (e.g., bending backward or prolonged standing) or compressive loading. While stenosis may result from trauma, congenital anomalies, or systemic diseases, approximately 80% of lumbar spinal stenosis cases are degenerative in origin. Common degenerative contributors include intervertebral disk bulging or herniation, facet joint hypertrophy (arthritis), ligamentum flavum thickening, spondylolisthesis (vertebral slippage), and osteophyte (bone…
