Carpal tunnel syndrome is caused by the compression of median nerve of wrist (nerve from arm to finger). The three fingers "commanded" by the median nerve, thumb, forefinger and middle finger, will first produce pain and numbness.
At the initial stage, it is often manifested as fingertip sensory dysfunction. A few hours after falling asleep, I often wake up with numbness or burning pain, and relieve myself after exercise. If some patients have extreme wrist flexion, the abnormal feeling of fingers will be aggravated after 60 seconds, which is a sign of diagnosis.
There are five times as many female patients as male patients with carpal tunnel syndrome.
Men missed diagnosis because of "less complaints"
It is understood that carpal tunnel syndrome is common in 30-50 years old, and female is five times that of male. Patients with both hands accounted for about 1/3- 1/2 of the total number of patients, while the ratio of female patients with bilateral diseases to male patients rose to 9: 1. As for why the incidence rate of women is much higher than that of men, one of the reasons is that women are more engaged in tedious, meticulous work that requires frequent physical labor, and another more interesting reason is that "women care more about their physical feelings, are more likely to perceive physical pain, and tend to" make a fuss "about pain, while men are just the opposite.
Dr. L Padova of the Italian Carpal Tunnel Syndrome Research Group believes that in fact, the number of men and women engaged in the same type of work is similar, but it is difficult for men to be diagnosed with Carpal Tunnel Syndrome. "A study of 740 patients showed that men complained less about pain and often felt that their hands were functioning well. However, neurological assessment shows that their injuries are more serious than those of women. " Dr. L. Padova appealed, "Men may only go to see a doctor when the symptoms of carpal tunnel syndrome become serious. So many minor cases were missed. It can be speculated that the incidence of carpal tunnel syndrome in men is underestimated. "
Once I woke up in the middle of the night with numbness in my hands.
Consult a doctor as soon as possible.
The typical manifestations of carpal tunnel syndrome are numbness and pain in the wrist, palmar surface, thumb, index finger and middle finger, or accompanied by inflexible hand movements; Pain symptoms worsen at night or in the early morning, which can radiate to elbows and shoulders, and can be relieved after daytime activities and throwing hands; The sensation in the above parts is weakened or disappeared; Even hand muscle atrophy and paralysis.
If this happens, and it has not been alleviated for several days, experts suggest that you must go to a regular hospital as soon as possible, make an early diagnosis and take measures. Clinically, some patients will suffer from thenar muscular atrophy under the thumb due to long-term pathological changes; Even intermittent skin whitening and cyanosis may occur; In severe cases, cyanosis of thumb and forefinger, fingertip necrosis or atrophic ulcer may occur, which becomes irreversible changes.
At present, there are the following treatment methods: 1. External fixation. If the symptoms are obvious, fix the wrist with plaster support or splint in mild dorsiflexion position for 65,438+0-2 weeks. Carpal tunnel closure: every week 1 time, 3-4 times, procaine and prednisolone (hormone) were injected into carpal tunnel. Third, take anti-inflammatory and analgesic drugs. Fourth, surgical treatment: those who are ineffective in non-surgical treatment or have aggravated symptoms or thenar muscular atrophy should be treated surgically as soon as possible, such as cutting off the transverse carpal ligament and relieving the compression on the median nerve. However, carpal tunnel closure is the main cause of most patients, which can be supplemented by anti-inflammatory and analgesic drugs.
How to prevent carpal tunnel syndrome caused by computer
Maintaining a good operating posture is the best way to avoid related injuries.
1, the keyboard should be placed in the center right in front of the body, and the height should be close to the keyboard or use the mouse to prevent carpal tunnel injury;
2. When operating the keyboard, the wrist should be as flat as possible, and don't bend or sag;
3. The working angle of elbow should be greater than 90 degrees to avoid compression of the median nerve of elbow;
4. Keep your forearms and elbows as close to your body as possible, relax as much as possible, and avoid leaning forward when using the mouse;
5. Make sure that when using the mouse, the wrist is straight and the sitting posture is correct. It is best to use a high-quality back pad and put your feet flat on the ground or foot pad.
6. The height of the display screen in front of the body should not allow the head to move up and down. When sitting up, your eyes should be parallel to the screen in a straight line to ensure that the brightness of the display screen is moderate.
7. When working, the operator often stretches and relaxes, and can bend his wrist slowly, and repeat it every hour 10 second; You can also do 10 seconds of fist clenching every hour.
