Prevention And Treatment of Tenosynovitis?

Prevention and treatment of tenosynovitis?

In recent years, excessive use of fingers, such as long-term use of smartphones, has resulted in more and more people suffering from tendinitis symptoms such as "De Quervain's disease" and finger bending. Especially those who raise children, those who often use their fingers and often operate the keyboard, they are more likely to develop tenosynovitis. Their wrists are easily strained, and the roots of their fingers are prone to pain and swelling.

The tendon sheath is a kind of tissue, like a pulley, which wraps the tendon that connects the bones and muscles and supports the tendon to move smoothly. Tenosynovitis is a disease in which tendon sheath and tendon rub against each other and cause inflammation. "De Quervain's disease" is mainly caused by overuse of the thumb. When the tendons that stretch and spread the thumb and the tendon sheath surrounding them become inflamed, it can cause swelling and pain in the back of the hand, and the bending and extension of the thumb can cause pain in the wrist. Because it also occurs when using a smartphone for a long time, it is often referred to as "text thumb injury" on the Internet.

Not just the thumb, "Trigger Finger" is a symptom called the "spring phenomenon". When the finger is bent and stretched, it gets stuck like a spring. This is a symptom of tendinitis that occurs due to inflammation between the tendon used to bend and stretch the fingers and the tunnel-like "ligament sheath" that inhibits the elevation of the tendon. Because tendinitis is mainly caused by excessive use of fingers, it is more common in people who like to exercise, repeatedly use the computer keyboard or mouse to operate, operate a smart phone for a long time, and play the piano. As we all know, it is very common in menopausal women and pregnant women, and it is believed to be related to the secretion of female hormones.

If you operate a smartphone with only the thumb of one hand for a long time, it will cause the thumb to be overused and tend to cause tendinitis. If you continue to operate in an unreasonable posture, it may strain the muscles that stretch the wrist, causing pain in the elbow and numbness of the fingers. So be careful not to overuse your mobile phone, so as not to burden your body. Even if you feel pain in the roots of your fingers or wrists, or if you feel inconvenient when bending and stretching, if the symptoms are mild, it is recommended to use over-the-counter drugs and wrist brace for self-care first.

Tenosynovitis is mainly treated conservatively, with external analgesics, compresses and other anti-inflammatory drugs, and fixed with wrist brace to ensure the rest of the affected area and prevent overuse. Steroids can also be injected to reduce inflammation. If after a few months of conservative treatment, the affected area does not improve or inflammation recurs, or the pain persists for more than 2 weeks and the affected area is swollen, please go to the hospital for treatment in time.

When the tendon sheath becomes inflamed, chemicals such as pyrokinin and histamine are released. It also produces a substance called prostaglandin, which causes pain to increase. The ingredients called "non-steroidal anti-inflammatory drugs (NSAIDs)" contained in anti-inflammatory drugs such as topical analgesics and compresses have the effect of inhibiting the production of prostaglandins and alleviating pain and fever. NSAIDs can be taken orally, but topical drugs can be effective by penetrating directly from the skin to the inflamed area. We need to choose drugs according to the location and symptoms, and choose the drugs that suit your painful location and symptoms. There are two types of topical analgesics and anti-inflammatory drugs, such as plasters and tapes, as well as lotions, creams, and gels.

In order to prevent tendinitis, it is important not to overuse your hands and fingers, but most people have to take care of children or work for a long time, so we will introduce you to daily life concepts that are unlikely to cause tendinitis. First of all, it is necessary to prevent overuse of the finger. Tenosynovitis is caused by the overload of the tendon that moves the finger and tendon sheath. Not overuse is the first step to prevent. Secondly, avoid long-term continuous work, pay attention to occasional stretching and rest, and use pads that can reduce the burden on the wrist when hitting the keyboard and operating the mouse. It is also a good idea to fix the wrist brace and other items. Don't use one hand to operate the smartphone, it is best to use both hands.

As we all know, postpartum women are more susceptible to tendinitis because they take care of the baby for a long time and use their wrists and fingers to hold the baby. It is recommended to adjust the posture to reduce the burden or use a wrist brace to protect your wrists and fingers. In addition, pay attention to maintaining the correct posture during exercise. Incorrect grip and ball grip will press on your fingers and cause tendinitis.

If you notice the first symptoms of tendinitis, such as finger pain, swelling, fever, or difficulty moving, be careful not to move as much as possible. For early inflammation, it is best to apply cold compresses with ice packs first.
