Lumbar disc herniation is one of the most common causes of back and leg pain. In terms of pathogenesis, lumbar disc herniation has both internal and external factors. The internal causes are degenerative changes in the disc itself (commonly known as aging), developmental and anatomical weaknesses of the disc, etc. The external causes are diverse and include changes in spinal biomechanics such as injury, strain and small joint disorders. It can be said that internal factors are the basis and external factors are the causative factors or necessary conditions. The reason for the high incidence of lumbar disc herniation in winter is that there are more factors that trigger lumbar disc herniation in winter. So, how to prevent lumbar disc herniation? Since degenerative changes in the lumbar spine and intervertebral discs are a gradual physiological process that evolves with increasing age, we cannot stop this aging process. The focus of our prevention of lumbar disc herniation should be on the elimination of the external causes that trigger lumbar disc herniation. Specific measures are: (1) efforts to avoid indirect or direct injury to the lumbar region, especially the lumbosacral region. Cold days and slippery roads increase the chances of trauma to the lumbar spine. When the lumbar intervertebral discs are under sudden or continuous pressure, they can all be herniated. Therefore, you must usually move or lift heavy objects, twist or bend your back in a prepared and defensive manner; pay attention not to straighten your back violently after a long period of bending; prevent falls, and once you fall, if you land on your buttocks, sometimes the lumbosacral discs will protrude; also beware of the slight twisting of the waist that occurs in certain specific positions to avoid triggering lumbar disc herniation. Especially the elderly, in labor and sports activities, to force properly, reasonable movements, not to make the waist twist flash. The lumbar disc herniation caused by direct external injury to the lumbar region is less common, but also try to avoid. Long-term, too heavy work, such as do not pay attention to the combination of work and rest, will cause the accumulation of intervertebral disc lotus damage, coupled with intrinsic factors such as intervertebral disc degeneration, and even easy to cause rupture of the annulus fibrosus, herniated nucleus pulposus. Those with congenital deformities of the lumbosacral region should pay more attention to protecting the lumbar region during labor or daily exercise to prevent injury. If lumbar trauma can be reduced to a minimum, then more than half of lumbar disc herniation can be prevented. (2) Promote correct lumbar posture. In the course of daily life, work, study and exercise, you should consciously adopt a comfortable and beneficial body position, maintain the natural physiological curvature of the lumbar spine, make the relative balance and coordination of the lumbar back and abdominal muscles, and reduce the pressure or torsion of the lumbar region as much as possible. To adhere to a good lumbar posture is not an easy task, need to have a strong will, perseverance and endurance. Even at home, especially for teenagers, it is important to consciously regulate lumbar posture to avoid unbalanced pressure and cumulative damage to the intervertebral discs from poor posture. Do not stand for too long and should change position at the right time to prevent the occurrence of lumbar synostosis. (3) Actively treat diseases related to lumbar disc herniation that can easily induce lumbar disc herniation. Winter is prone to colds, and diseases such as colds, rhinitis and constipation should be treated promptly and cured as early as possible to eliminate symptoms. This is because colds and rhinitis tend to trigger violent coughing or sneezing, which increases the pressure in the spinal canal and predisposes to lumbar disc herniation. Constipation is difficult during defecation, which increases the intra-abdominal pressure, which in turn increases the pressure on the intervertebral disc, with the possibility of damaging the fibrous ring. Excessive obesity and thinness also predispose to lumbar disc herniation. Therefore, do not think that the cold and other minor problems, haphazardly deal with it, should know the “small does not cure, is to cause a major disease”. (4) strengthen the cold and warm measures for the waist. Once the waist is attacked by cold and damp, not only can cause rheumatic lumbago and lumbar muscle strain and other diseases, but also the chance of lumbar disc herniation. The reason is that the cold dampness makes the lumbar back muscle blood circulation is obstructed, the muscle force under the rung, so that the spine is unstable, the intervertebral disc to withstand greater pressure, such as the basis of the original degenerative disc degeneration, it is very easy to make the nucleus pulposus protrude. Therefore, the waist ah plus lumbar protection, is not a good way. Of course more important is to wear warm enough clothes. Experience has proven that it is a brilliant and rational strategy to prevent lumbar disc herniation in the first place.
