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.
The spinal canal contains the spinal cord, which is a nervous structure responsible for the transmission of all nerve impulses that come from members and the brain that carry nerve stimulation of the brain to the nerves and, consequently, to the muscles of the body. Causes of cervical spondylosis: There is no single cause for cervical spondylosis. There may be a predisposition to it in people whose spinal canal is congenitally narrow. Repeated minor trauma contribute to the intervertebral discs are damaged gradually, starting the process of spondylosis. Some occupations and sports increase this risk. Another important factor is smoking, because it jeopardizes the micro-circulation and affect the nutrition of the disc. Osteophytes, ligaments and articular facets hypertrophied and protruding disc fragments together, reduce the canal and the vertebral foramen, causing compression of the spinal cord and spinal roots.
The most common manifestations are neck pain and limitation of neck movement. Escort is often a sense of hearing "sand in the column, their movements. The person concerned has the impression that "no lubrication in the column. These changes are extremely frequent with advancing age and has no greater importance.
In some people, however, the narrowing of the canal and vertebral foramen leads to nerve compression. These cases occur three forms of commitment and should be evaluated by medical specialist. A radiculopathy is compression of a nerve root. It is manifested by pain radiating from the neck to the shoulder blade and one upper limb, following a path well-defined and constant. It is followed by a feeling of tingling or numbness in the same way from the shoulder to certain fingers.
Express themselves in numbness in the first two fingers, index and middle fingers; two times there is also loss of strength of a muscle group, which also depends on the root or roots compromised. You can, for example, express a loss of flexion strength of the forearm, or its extension, or of certain fingers. Myelopathy is spinal cord injury, compressed as a result of spondylosis.
It is manifested by progressive loss of movement of members No Pets. It starts, usually, by progressive difficulty in walking, accompanied by a feeling of tightening of the muscles of the lower limbs. There is loss of ability to command the legs and progresses to the same deficit in the upper limbs. I get a feeling of numbness in the legs and trunk, which ascends gradually. It is followed by a sense of urgency to urinate and that evolves into an inability to hold urine. In men, there are also erectile dysfunctions. The myeloradiculopathy is a combination of radiculopathy and myelopathy, with manifestations of both.
The simplest cases, which are also the most frequent, in which there is impairment of nerve function, and are treated symptomatically with exercises designed to improve cervical range of motion, and correct posture when changed. In cases where there is only radiculopathy, one could try conservative treatment with anti-inflammatories, painkillers.
When these measures are not followed by functional recovery, may be indicated to surgical decompression. In cases where there is progressive myelopathy, treatment should be surgical decompression of the spinal cord.
