2, cervical spondylosis: The most common disease causing hand numbness is cervical spondylosis, which is one of the diseases that are prone to middle-aged and elderly people. When people enter middle age, some organs tend to degenerate. When cervical intervertebral disc degenerates, it often leads to cervical intervertebral disc protrusion or articular process hyperplasia or hypertrophy. Once these protruding cervical intervertebral discs or hyperplastic articular processes compress the adjacent cervical nerve roots, cervical spondylosis will occur. In addition to numbness of fingers and abnormal sensation, cervical spondylosis is accompanied by other symptoms, such as neck and shoulder pain, radiation pain of upper limbs or dyskinesia. It is not difficult to diagnose cervical spondylosis. Just take an X-ray. In addition, there is a simple method to check cervical spondylosis. One person holds the head of the affected side, one hand holds the upper limb of the affected side, abduction is 90 degrees, and both hands push and pull in the opposite direction at the same time. Those with radiation pain or numbness can be initially diagnosed as cervical spondylosis.
3. Stroke: Another common disease that causes hand numbness is stroke. "Health Treasure in the Air Door" once said: "Anyone who feels that his thumb and second finger are insensitive or not used for the first time will have a stroke within three years." Precautions must be taken: live carefully, eat frugally, stay away from home and be broad-minded. Although finger numbness does not necessarily lead to stroke, for middle-aged people over 40 years old, if they often have symptoms such as headache, dizziness, top-heaviness, numbness of limbs and swelling of tongue, and patients usually suffer from diseases such as hypertension, hyperlipidemia, diabetes and cerebral arteriosclerosis. They should pay more attention to and be alert to the occurrence of stroke.
4, menopausal syndrome: women who enter menopause sometimes have hand numbness, but it is not obvious, with the end of menopause, hand numbness will disappear.
In short, the diagnosis of hand numbness symptoms needs to refer to cervical radiographs, electromyography and other auxiliary examinations to make a clear conclusion. Once diagnosed, if the symptoms are still mild, they can be improved to varying degrees through regular non-surgical treatment. If the symptoms are obvious and there is obvious muscular atrophy in the hand, surgical treatment should be carried out in time to prevent the development of the disease, so as not to cause irreversible severe atrophy of the internal muscles of the hand and lead to serious dysfunction of the hand.

What is the cause of hand numbness?
1. Vascular factors:
When we sit for a long time or sit badly, it will cause numbness in the lower limbs and numbness in the wrong posture of our hands. ) because when blood vessels are compressed, blood vessels supply limbs with ischemia, causing numbness. When the oppression is released and the blood flows, there will be many ants crawling. As shown in the figure, when the ulnar artery and radial artery of the upper limb are compressed somewhere, they will cause hand numbness.
2. Neurological factors:
Nerves have axial flow. When the nerve is compressed, the axial flow is blocked, which can also cause hand numbness. As shown in the figure, the palm mainly includes radial nerve, ulnar nerve and median nerve. These nerves start from the cervical spinal canal, pass through joints, ligaments and bone fiber tubes, and reach the palmar apex. Any part of the nerve is compressed, which will cause numbness in the hands.
3. Brain factors:
All nerves come from the brain. When something goes wrong with the brain, such as a stroke, the area dominated by the brain will be numb and powerless.
4. System factors:
Some systemic diseases, such as:
A. Hyperlipidemia: Hyperlipidemia for a long time can easily lead to vascular wall sclerosis. In addition, hyperlipidemia, thick blood, slow blood flow, and reduced oxygen nutrients for cells will all lead to numbness.
B. Diabetic patients: maintaining blood sugar at a high level will cause great damage to human blood vessels and nerves for a long time, arteriosclerosis and neurodegeneration.
Numbness of hands and feet is a common symptom in people's daily life, such as pregnancy, incorrect sleeping position, squatting in the toilet for a long time, etc., which are generally eliminated in a short time without any major problems. But some people have been numb for a long time (more than one day) and have to see a doctor. But which subject should I study? Experts say that no matter what causes numbness in hands and feet, neurology should be consulted first.
The causes of numbness in hands and feet generally have the following four aspects:
First, people with diabetes will be numb in their hands and feet. As long as numbness, soreness and swelling often appear in any part of the body, it is necessary to check blood sugar in time, especially in the elderly.
The second is numbness caused by drugs or chemicals. If you have a cold or diarrhea, taking berberine or furazolidone will cause numbness in your hands and feet; Staying in an environment containing hydrogen, arsenic and carbon disulfide for a long time can also cause numbness in hands and feet.
The third is numbness caused by neuritis. The most common symptoms of neuritis are numbness of hands and feet, muscular atrophy and weakness of limbs. If you have diarrhea or catch a cold for half a month, it will cause neuritis.
Fourth, the limbs are scattered and numb. Numbness of limbs does not occur at the same time, but is scattered. This situation is that local nerves are stimulated, such as stroke coma after drunkenness, nerve stimulation in the head, nerve stimulation in the hands of the elderly with crutches, numbness in the upper limbs caused by cervical spondylosis, and numbness in the legs caused by waist and shoulder nerve stimulation.
Numbness of hands and feet cannot be treated symptomatically, but the cause should be treated. No matter what causes numbness in hands and feet, you should first go to the hospital neurology department to check whether there is nerve damage and what kind of stimulation you have received. If it is a neurological problem, electromyography is needed to further confirm the degree, scope and nature of nerve injury. If the numbness of hands and feet is caused by other reasons, it will be transferred to other relevant departments for treatment. The numbness of hands and feet caused by nerve injury should be treated with drugs or surgery according to the degree, scope and nature of nerve injury. Drug therapy is usually combined with acupuncture and physical therapy to promote its rapid recovery. Surgical treatment is to open the compressed nerve by surgery to relieve the oppression and stimulation of the nerve. The degree of cure of the disease mainly depends on the etiology and nature of neuropathy. If it is peripheral nerve injury (except brain and spinal cord), it usually takes a long time to recover.
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).
Relationship between lumbar flicker and lumbar instability
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.
3. 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.
