Flash is a sign of lumbar instability. Occasionally, it may not cause lumbar instability, but it will easily cause lumbar instability if it happens repeatedly. The normal lumbar spine is connected by five bones, including intervertebral disc, back joint, joint capsule and ligament. Ligament connection plays a very important role in the stability of lumbar spine. When the patient flashes back or flashes back repeatedly, it actually indicates that the normal structure may be damaged. Cartilage disc is an important factor causing instability after injury. Through bending and stretching X-ray films, we can see that the mobility between vertebrae increases in the unstable stage of lumbar spine, which in itself shows that the normal structure has been destroyed. Originally, the connection between vertebral bodies was relatively orderly, but in the abnormal stage, some of them actually moved forward, which is also a manifestation of lumbar instability.

Under normal circumstances, before 18 years old, the water content of nucleus pulposus accounts for 80%. After the age of 30, the water content and elasticity of nucleus pulposus gradually decrease. After the height of the intervertebral disc is reduced, the ligament is easy to relax. In the case of abnormal pressure, some abnormal pressure increases, which is easy to cause lumbar sprain and instability. There are also some genetic reasons. We have seen 10 children with disc herniation. We think this may be caused by genetic factors or other reasons.

What is the cause of the flicker?

In fact, you don't need strenuous exercise to flash your waist. Lumbar flicker seen in clinic often occurs when attention is not concentrated. The main reason is that the intervertebral disc is damaged and the stable structure is reduced. At this time, muscles need a lot of strength to protect. When doing the action with great attention, the muscles are in a state of tension. It's not easy to flash at this time. When the attention is not concentrated and the muscle strength is not enough, it will flash. In fact, this kind of waist flicker has a lot to do with long-term living and working conditions. For example, if you keep a posture for a long time or some postures require great strength to maintain, the cartilage will be damaged. Cartilage needs nutrition and needs to be increased through activities, not directly supplied by blood itself.

What should I do after flashing my waist?

Once you have low back pain, you must see a professional doctor. In the past, many structures were usually removed for lumbar disc herniation surgery, and both normal structures and intervertebral discs were surgically removed. Although the nerve compression was relieved at that time, severe low back pain appeared later, which reflected that the resection of these tissues and the original factors caused lumbar instability.

At present, it is still under discussion whether there has been lumbar instability in this state after disc herniation. If it is found that lumbar instability has occurred, it is necessary to find out the unstable part and then fuse and fix it for the unstable part. If there is no spinal instability in disc herniation, but the nucleus pulposus compresses the nerves, the operation should be minimally invasive, and the structure of ligaments and joints should be preserved as much as possible to alleviate the symptoms and maintain the relative position as much as possible.

Relationship between lumbar spondylolisthesis and lumbar instability

Lumbar spondylolisthesis is a special form of lumbar instability. There are usually three situations: 1, congenital factors, and vertebral instability during development. This slippage is very serious, sometimes even reaching 3-4 degrees. 2. Fatigue fracture of lumbar spine caused by an abnormal activity in youth. This kind of fatigue fracture had no symptoms at that time, but the structural changes after the fracture existed. 3. Due to the change of intervertebral disc, the water content is reduced and the stability is reduced.

Clinical manifestations of chronic low back pain caused by lumbar instability

1, recurrent low back pain

2, often aggravated after fatigue.

There is an uncomfortable feeling of disconnection at the waist.

4, can not adapt to the semi-bending posture

5, feel pain when changing positions, waist and buttocks pain in the morning.

6, can't keep a posture for a long time, and there are often predictable pain attacks in climate change.

To what extent does chronic low back pain need surgical treatment?

Although chronic low back pain is common, not all of them need surgery. If there are some unexpected situations, such as nerve compression, not only low back pain, but also some symptoms of leg weakness and numbness, then surgery should be considered. Some people have severe pain, which seriously affects their daily life and long work hours. If the quality of life is seriously affected, surgery should be considered.

Is lumbar surgery risky?

This is the most concerned problem for patients. Objectively speaking, there will be certain risks, but with the progress of medical technology, this risk is gradually decreasing. Judging from our actual work situation, this operation is not very dangerous.

Do you need long-term bed rest after operation?

In the past, because there was no good fixation method, it was necessary to stay in bed for a long time after operation, waiting for the bone to heal. Now this kind of internal fixation method and technology has been more advanced, and it has also improved these unfavorable factors after operation. You can wear a waist protector to the ground three days after operation. A very important purpose of surgical improvement is to speed up the recovery of patients.

Postoperative rehabilitation

Let the patient exercise the function of the back muscles after three months, and keep raising his head to exercise the isometric contraction of the back muscles for five seconds. It usually takes three months to six months to exercise abdominal muscles, lift legs, increase flexibility and wear waist protection in turn.

Usually, we should also pay attention to doing more exercise, which can effectively prevent waist diseases. For example, sit-ups can exercise abdominal muscles, and you can also exercise back muscles in bed to make muscles contract in equal length. In addition, people who don't exercise regularly or have low back pain are advised to avoid strenuous exercise like football and basketball. Lumbar sprain is commonly known as "flashing waist". Most people often bend down to lift heavy objects and suddenly flash to their waist. I hope you can avoid this behavior. First aid focuses on maintaining a comfortable posture, resting and cold compress.

Lumbar sprain is caused by sudden tension of waist muscles when bending over to pick up heavy objects.

When you sprain your back, you should first keep a comfortable posture and rest quietly. At this time, you can bend over in bed, but don't lie on a mattress that is too soft.

You should avoid lying on your back and keep your feet straight. This will not only increase the pain, but also paralyze the feet.

Cold compress can relieve pain. So you might as well use a wet towel to cold compress your waist.

Mild lumbar flicker can be cured automatically as long as you rest for 1-2 days. But if the pain persists or becomes more and more painful, you need to see a doctor as soon as possible (plastic surgery).

In addition, not only muscle pain, but also disc herniation may cause low back pain, so you should go to the hospital for examination when you have low back pain.
