- Cervical osteochondrosis - the lot of office workers
- What to do
Cervical osteochondrosis is most often caused by prolonged sitting with bowed head, for example, when working on the computer. Very often this type of osteoarthritis developed at a young age, if the work is related to forced postures. For the prevention of osteochondrosis
Preventing osteochondrosis - should be carried out in youth
for working for physical exercise are recommended to do a five-minute break from the exercises, relieves spasms of the neck muscles.
The structure of the cervical spine
Cervical spine represented by seven cervical vertebrae, one above the other, separated by a 6 elastic intervertebral disc, providing the flexibility of the spine. Each vertebra distinguish its main parts - the body, bone, and several arc processes: one spinous (it faces backward), two and four transverse joint (two on each side).
At the junction of the arc with a vertebral body are the upper and lower vertebral scraps that form in the spine the intervertebral holes through which the spinal nerves, blood and lymph vessels. The size of the intervertebral hole in the neck is smaller than in other parts of the spine.
The load on the cervical vertebrae is small, so their bodies are small. The transverse processes of the cervical vertebrae 1-4 are special openings for the passage of the vertebral arteries that carry blood to the brain. When osteochondrosis hole size can be reduced - this leads to symptoms of cerebral circulation.
Between the vertebrae are intervertebral discs (the cartilaginous spine, between the first and second cervical vertebra disc is missing), consisting of the fibrous ring, inside of which is the nucleus pulposus diameter of 1-2, 5 cm. The fabric is a core cartilage cells, intertwined fibers. In young adults in the nucleus contains more than 80% water, the elderly - 70%, the viscosity and elasticity is lost gelatinous tissue metabolism slows

in the nucleus.
A feature of the intervertebral discs is a poor blood supply. Because of this, the restoration of the destroyed osteochondrosis disk is almost impossible. Nutrients cells disc received by percolation (diffusion) of the extracellular tissue. If a person moves a little, diffusion processes are reduced, and when activated motor mode increases. The intervertebral discs connect the vertebral bodies to regulate the mobility of the spine and protect the bone from the vertebrae injury. In addition, the stability and mobility of the spine is provided by ligaments and muscles.
Two vertebrae interconnected by a disc with two joints and ligaments, called the vertebral segment. In the cervical spine five segments. When osteochondrosis often affects the lower segments of the cervical spine.
From the spinal cord in the cervical spine moves forward eight pairs of nerve (mainly motor) and posterior (mainly sensory) roots that go through the intervertebral holes and combined with each other in the spinal nerves. Spinal nerve roots also contain autonomic nerve fibers that innervate the internal organs and blood vessel walls.
Cervical spine is bending forward (cervical lordosis). Curvature of the spine provide a springy movement of the human body. Cervical - the moveable spine mobility is carried out by shifting 4-6 vertebrae relative to each other by bending the neck. But it also contributes to narrowing of the intervertebral foramen, ie create additional conditions for infringement of spinal nerves.
The causes of cervical degenerative disc disease
Causes of cervical degenerative disc disease, usually multiple. With age, changes occur as the body of the vertebrae and intervertebral discs: vertebral bodies lose calcium and become brittle, change shape, and the intervertebral discs lose moisture and made flat, thin and inelastic. This process is unique in many ways - found that great importance is the hereditary features of the structure of the spine and metabolic processes in cells drives.
Metabolism in the cells drives aggravated by a sedentary lifestyle (broken cell nutrition), sustained high physical activity (chronic mikrotravmirovanie disks), a variety of chronic diseases, resulting in overall metabolic disorders, exposure to various chemicals coming from outside (eg, nicotine) , hormonal disorders
Hormonal disorders - oversupply and a lack of equally dangerous
and so on.
The aggravation of cervical degenerative disc disease may start with a sharp turn of the head, colds, some external influence. For example, a dangerous combination - cervical osteochondrosis and alcohol, as the latter can cause a persistent constriction of blood vessels and increased degenerative processes in the intervertebral discs.
Stages of cervical degenerative disc disease
The intervertebral discs in the cervical osteochondrosis gradually destroyed. In this process, there are four steps (degrees)
- cervical osteochondrosis 1 degree - minor changes in the intervertebral discs; most often it does not manifest;
- 2 degrees of cervical osteochondrosis - protrusion (bulging of the disc into the spinal canal without breaking the fibrous ring) disc, reducing the distance between the vertebrae, pinched nerves, pain;
- cervical osteochondrosis
Osteochondrosis - learn how to properly distribute the weight
Grade 3 - the appearance of intervertebral hernia (rupture of the fibrous ring and exit the nucleus pulposus outside of the spinal column), and a significant deformity of the spine;
- cervical osteochondrosis 4 degree - growth of bone tissue and a decrease in the mobility of the spine (deforming spondylarthrosis) - normal traffic can become a cause of severe pain; disability with cervical osteochondrosis develops at this stage.
