Spondylosis refers to a degenerative process affecting the vertebral disc and facet joints, which gradually develops with age. A common form of spondylosis is cervical spondylosis (sometimes called neck arthritis) in which the facet joints in the neck become enlarged and causes the ligaments around the spinal canal to thicken and bone spurs to form. The chronic compression can lead to damage to the spinal cord, causing symptoms such as weakness and numbness in the upper extremities, impaired walking ability, and radicular arm pain.
