Spondylosis

The root term [-spondyl-] arises from the Greek [spondylos] meaning "vertebra", and the suffix [-osis] means "condition", but with the connotation of "many". The word [spondylosis] means " condition of many vertebrae". This does not add much to the use of this word as an indicator of a pathology, but it does indicate that there is excess bone in a vertebral pathology.

Spondylosis is an osteoarthritic degeneration of the vertebrae and the spine characterized by abnormal bony growths  on the vertebrae that can impinge on nerves and other structures causing pain and mobility problems. The definition of spondylosis also includes degenerative changes in the intervertebral discs.

The abnormal growth of portions of the vertebral body, usually forms "bone spurs", also referred to as "spondylophytes". The accompanying image shows a lumbar vertebra with spondylophytes. Click on the image for a larger depiction.
