Radiculopathies discogenic (banal radiculites) - the painful, motor and vegetative disturbances caused by a lesion of roots of a spinal cord owing to an osteochondrosis of a backbone.

Etiology, pathogenesis. An osteochondrosis of a backbone - the is degenerate-dystrophic process arising because of loss by intervertebral disks of their function of amortization that is caused by the degeneration of a tissue of a disk leading pressure decrease inside of it. Except for cases of a trauma, the etiology of a diskopathy is obscure. In a segment of the amazed disk there is a relative instability of a backbone with development of osteophytes of bodies of vertebra (spondylosis), damage of ligaments and an arthropathy of intervertebral joints (spondylarthrosis). A diverticulum of a disk (a protrusion or a hernia), and also osteophytes can squeeze roots, causing thus radicular pains.

Besides as a source both local, and pains irradiating in an extremity the damaged tissues of a backbone serve also. An immediate cause of occurrence of pains - the raising of gravity, awkward movement, cold, negative emotions, infections, etc. as a whole not less than 95 % of cases of a lumbosacral and cervical radiculitis are caused by an osteochondrosis, and in a basis of radiculopathies the mechanical, compression factor lays, as a rule.

The first attacks of lumbar and cervical pains, apparently, are bound to an anguish of a fibrous ring of a disk and damage of capsules of intervertebral joints. Thus mainly vegetative innervation suffers, and the pain happens diffusive (lumbagos, myosites). Only development of a hernia of the disk squeezing a root, leads to formation of actually radicular syndrome.

Cervical radiculitis. The first attacks of illness - a pain in a neck, a strain of the cervical muscles, the compelled position of a head, straightening of a cervical lordosis. In case of development of a hernia of a disk and a prelum of one of roots (more often C6 or C7) the pain extends in an arm, a scapula or a forward surface of a thorax; in the latter case the myocardial infarction is quite often imitated. The pain amplifies from tussis, movements of a head.

Thoracal radiculitis. A girdle pain at a level of a thorax or a stomach. Exclusively rare variant of a banal radiculitis.

Lumbosacral radiculitis. At the next exacerbation the pain extends in a leg, is usual on a course of a sciatic nerve as more than 90 % of cases of a syndrome are caused by a prelum of roots L5 - S1. To a pain delicacy of extensors of the big finger or quite often accompanies all stops.
