Instability of the spine is apathological mobility in its segment. At the same time, the amplitude of normal motions either increases, or new freedoms appear in the movements that are uncharacteristic for the normal state. A measure of mobility is the displacement of the vertebrae. At the same time, the bias refers to an X-ray finding and may not be accompanied by pain. Instability refers to the clinical concept and is characterized by pain.
The most vulnerable is the cervical region. She is responsible for the person's thinking abilities, his ability to speak, work with his hands and other "human" qualities. The cervical segment includes seven vertebrae. The first ("atlant") does not have a body. There is also an intervertebral disc, and a spinous process. "Atlant" is tightly fused with the skull and carries all its load on itself. From the second cervical vertebra, the "tooth" (outgrowth) departs. At him, "Atlant" is planted. This joint and the joints between the vertebrae allow the first vertebra to turn.
Due to the lack of a disk, this site is notis affected by osteochondrosis. However, cervical vertebral instability often occurs. At the same time their position is characterized by increased mobility. The reason for the instability of the cervical spine in this area may be a congenital anomaly, trauma (including lungs). Increased mobility also occurs with prolonged work with the head tilted down and forward.
The rest of the cervical departmentvertebrae, have a similar structure with thoracic and lumbar vertebrae. This causes and the occurrence of similar violations in them. To them carry: deterioration in intervertebral disks and joints, formation of osteophytes (bone growths). There are also hernia discs, which are able to squeeze the roots of nerves. All this causes instability of the cervical spine.
This is the most mobile zone of the pillar. Especially in the area of the fifth-seventh vertebra. It is this area that wears out faster than others. Due to the appearance of painful processes, these vertebrae begin to cope badly with their functions. Since they are unable to withstand the load, it is distributed to adjacent segments. Additional load causes instability of the cervical spine already on its next site.
United together segments formThe spinal canal, whose origin is in the region of the large foramen of the occiput. The transverse processes of the vertebrae of the cervical region have an opening for each artery on each side. Together, an arterial canal is formed. Instability of the cervical spine can lead to a lack of blood flow and, as a result, dizziness, coordination disorders, headaches, ringing in the ears, visual disturbances, and so on.
Increased mobility of segments canpromote and develop various autonomic disorders. This is due to the presence of a large accumulation of nodes of the nervous vegetative system among the surrounding surrounding cervical spine of soft tissues.
The functions of fixing and driving the upperThe segments of the column are performed by the muscles of its cervical region. Most of them have a rather fine structure and are very innervated. Any serious impact (hypothermia, sudden movement, uncomfortable posture, prolonged or increased load) can trigger a muscle spasm characterized by soreness. In this case, there is often a restriction of mobility in the neck. Even insignificant instability can provoke irritation in the nerve endings, a back spasm in the vessels and muscles. At the same time, pain in the head, inter-shoulder area and neck, dizziness and so on.
