Symptoms of lumbosacral radiculitis are well known. The disease begins with assault acute pain, or, as it is often said with our patients, “lumbago” in the back. The lumbar muscles are stretched. There is growing feeling of stiffness. Movements are painful and limited.
Onset of pain (lumbago) usually lasts several days. Then pain subsides, the spine is moving, and the person feels healthy. Yet even outside the attack may experience intermittent feelings of awkwardness, gravity in the lumbar region (the so-called lumbar discomfort).
With the passage of time, pain on the side or back of the legs can join to bouts of back pain. Man forced to take a posture in which pain is felt less. Some, for example, were relieved when the person lie down, put a pillow under her stomach. Sitting is usually easier with outstretched foot on one half of the buttocks, leaning both hands on the seat.
For a long time it was felt that the cause of disease is inflammation of the sciatic nerve caused by infection. A related name for the disease: sciatica, sciatic neuralgia. However, even at the beginning of this century, neurologists noticed that more often not the inflamed sciatic nerve, and forming his spinal roots. There is a new name for the disease radicular sciatica and lumbar-but-sacral radiculitis.
New data, obtained through the joint work of anatomists and radiologists, neurologists and neurosurgeons, physiologists and biochemists, indicate that the disease is most often associated with changes in the lumbar spine. What exactly, I’ll tell you.
Let me remind you before, that the adjacent vertebrae in the spine are connected to each other intervertebral joints and strong ligaments. Between the vertebrae are openings through which the radicular nerves. Cartilage elastic intervertebral discs perform the role of shock absorber. They also provide the flexibility of the spine. If by virtue of any reasons intervertebral joints are deformed, then narrowed intervertebral foramen and compressed radicular nerves. Man feels the pain. Such changes in the spine are called spondee-deforming arthrosis.
Sometimes the pain is associated with calcification of ligaments of the spine (spondylosis deformans), this phenomenon is sometimes erroneously referred to the deposition of salts.
But the most frequent cause of pain in lower back and legs are degenerative changes of the intervertebral disc osteochondrosis. And these changes are prerequisites, because intervertebral discs have greater static and dynamic loads.
For clarity, we present data obtained by measuring inside disk pressure and power disk compression in the lumbar region. It was found that the highest inside dick pressure noted is in the sitting position, up to 175 kilograms, in other words, 10-15 kilograms per square centimetre. In the standing position it is up to 120 kilograms. If you fall or jump the wrong load on the spine increases so that may be critical. We know that to break the normal disk requires axial compression force of 500 kilograms, but in osteochondrosis damage the disc comes with a much smaller axial compression force.
Mathematical analysis has shown that a person whose growth 160 centimetres and weight 65 kilograms, standing upright with his arms outstretched horizontally forward, the force of contraction of the last lumbar disc is 67 kilograms. If in such a situation to hold a weight of 10 kilograms, the force-compression utility will be 209 pounds! If the trunk is tilted forward at an angle of 90 degrees and the hands are omitted, this force will amount to 210 kilograms, and if one keeps to the same weight of 30 kilograms, the disk will experience a compression of 480 pounds. Often, for example, by coughing, sneezing, straining, while decreasing all the muscles of the trunk and spine compression forces up to 240 kilograms. That is why in such situations a person often feels pain.
As you can see on a daily basis throughout the life, our spine is experiencing heavy loads. However, we do not feel up to it as long as intervertebral discs retain their elasticity, good amortize.
With age in the aging organism elasticity titles released gradually decreases, decreasing their height, and the bodies of the vertebrae appear marginal growths (osteophytes). Although the 50 years these changes have already expressed, in normal circumstances, the specific disorder does not occur. Another thing, if under the influence of spinal injury or, more commonly happens, the long microtraumas wheels wear out prematurely. There osteochondrosis. This can happen in 40 and 30 years.
Who is most vulnerable to long microtraumas? People engaged in hard physical labour or constantly experiencing concussion (drivers of cars, tractors, trains), as well as those who have long stays in a bent position, or sitting, or commit the same type of motion. Changing discs is rather uneven and overloading of the spine, for example, people with congenital hip dislocation, curvature of the spine, as well as after the amputation of his legs. People with excess weight have also their intervertebral discs affected with it.
