Lumbar spinal stenosis is a narrowing of the lumbar central canal, nerve root canal or lateral saphenous fossa due to hypertrophy and hyperplasia of the ligamentum flavum, hyperplasia and coalescence of the small joints, bulging and herniated discs, and bony degeneration causing compression of its contents, the cauda equina and nerve roots, and corresponding neurological dysfunction. In clinical practice, lumbar spinal stenosis is one of the most common diseases causing low back pain or low back pain. Its main clinical features are neurological intermittent claudication, as well as weakness and discomfort in the buttocks, thighs, and calves, aggravated by walking or posterior extension, and another clinical feature is abnormal sensation in the saddle area (perineum) and abnormal bowel and urinary function.
