Cervical spondylosis is the set of changes resulting from osteoarthritis of the cervical spine. With age, intervertebral discs lose their elasticity, by progressive loss of its water content. When the nutrition of the disc becomes insufficient, there is loss of its constituents, which leads to reduction of disc height, the resistance to movement and traumas, even small ones, facilitating its disruption and degeneration.
These disc changes are followed by reactions of bone adjacent vertebrae, with the formation of osteophytes, or nozzle-to-parrot, which tend to fuse the vertebrae. This set of changes may predispose to a reduction of the spinal canal and foramen of conjugation.
