Cervical spondylosis refers to the degenerative condition of the cervical spine including the intervertebral joints in between the vertebral bodies and the vertebral discs.The other terms used for this condition are degenerative disc disease, degerative spondylosis, osteophytosis, spondylities deformans.
It is very common in persons above 50 years of age and those have got to do work like typing or persons who have to keep the neck in one position as in reading , writing and other table works.
Its starts with degeneration of disc resulting in reduced space in between two vertebrae, later osteophytes are formed in the periphery. This is followed by involvement of the posterior intervertebral joints resulting in pain in the posterior part of the upper limb. Gererally, theis pain is along with tingling, numbness and radiating in nature.
The osteophytes formed may also compress the cord which will produce weakness of whole of the limb.
