Lumbar spondylosis, or degeneration of the lumbar discs and facet joints, is a common feature of aging. This degeneration often presents without causing symptoms beyond a routine back ache. However, the tissue overgrowth, ligamentum flavum hypertrophy, and bony osteophytes that accompany the degenerative process can also cause narrowing of the lumbar spinal canal (spinal stenosis). These processes can compress the neural elements causing leg pain, lower extremity numbness, buttock pain, and weakness.
