cervical spondylosis at English => English (The Britannica Concise) Of Explained:
Degenerative disease of the neck vertebrae. Compression of the spinal cord and cervical nerves by narrowing of spaces between vertebrae causes radiating neck or arm pain and stiffness, restricted head movement, headaches, spastic paralysis, and arm and leg weakness. Cervical spondylosis can resemble neurological disease with unrelated arthritis. It is treated with rest, traction, and possibly a cervical collar. Removal of herniated disks or fusion of vertebrae may be necessary.
