Discogenic spondylosis, which is often thought of as a form of spinal osteoarthritis, refers to a degenerative condition that affects the joints of the spine.
Spondylosis is an umbrella term used to describe pain from degenerative conditions of the spine. Most spondylosis symptoms result from spinal osteoarthritis, but there may be other causes as well.Spinal osteoarthritis primarily affects the facet joints, which are paired joints on the back of each vertebral level.pondylosis may also refer to degenerative changes in the disc called degenerative disc disease, in which spinal discs begin to thin, lose moisture, and break down. Pain from degenerative disc disease can originate in the disc itself, or come from changes in the biomechanics of the spine.
