What condition leads to spinal stenosis?

Spondylosis is a degenerative condition of the spine, characterized by the wear and tear of the vertebral discs and joints over time. As the intervertebral discs lose hydration and elasticity, they can become less effective at absorbing shock, leading to disc bulging and the formation of bone spurs (osteophytes). These changes can contribute to the narrowing of the spinal canal, resulting in spinal stenosis.

The anatomical changes associated with spondylosis can compress spinal nerves or the spinal cord itself, leading to the symptoms typically associated with spinal stenosis, such as pain, tingling, or weakness in the limbs. Other factors that can contribute to spinal stenosis may include herniated discs or congenital anatomical variations, but spondylosis is a common underlying cause associated with age-related degeneration.
