How is the trigger finger formed? How is it treated?

The trigger finger is actually tenosynovitis. Refers to chronic aseptic inflammatory changes in the tendon sheath caused by mechanical friction. It is more common in manual workers, especially those who repeatedly stretch, flex, pinch and hold with their fingers, and it is more common in women than men.

There are two main types of finger muscles in people: flexors and extensors. These muscles are all attached to the bone by tendons, and their orientation is in line with the long axis of the bone.

The tendon sheath is an annular ligament perpendicular to the long axis of the tendon, which is placed on the outside of the tendon and holds the tendon in place. When the finger is bent or straightened, the tendon travels through the tendon sheath and rubs against it. Over time, the tendon sheath ligament will undergo edema, hyperplasia and adhesion, forming chronic inflammation, resulting in hypertrophy of the tendon sheath and narrowing of the lumen.

In other words, the tendon becomes hypertrophied, making it difficult to slide in the tube, and sometimes it can be stuck and cannot be straightened or flexed, and it needs to be used by external force to move normally. Whenever the fingers are flexed and extended, the tendon barely slides through the ring-shaped narrow tendon sheath ring, producing a "click" sound like a trigger. The disease is ineffective, stiff, and mildly painful at first, and the pain worsens over time, especially in the morning.

To a large extent, this disorder can be said to be overuse, which is caused by excessive incorrect exercise. **Generally speaking, braking rest, topical plasters, Chinese medicine soaking hands, if necessary, sealing. But the premise must be that the rest is fixed.

If the above methods still do not work, or if the tendon is swollen greatly, surgery is recommended. The method is simple and can be completed on an outpatient basis, generally an incorporation is made at the palmar striae, and the tendon sheath is separated by vascular clamp to avoid damage to the finger vascular nerve bundle. The tendon sheath is cut longitudinally by 2 cm, part of the tendon sheath is removed in a door shape, the tendon adhesions are released, and the patient is instructed to move his fingers until the snapping disappears.

Children also have trigger fingers, which rarely heal on their own, so early surgery is recommended.

Generally, women are more likely than men, pinching, resulting in hypertrophy of the tendon sheath.

Children also have trigger fingers. That is, the tendon becomes hypertrophied. The tendon sheath is cut longitudinally by 2cm, and the pain will worsen over time until the snap disappears, loosen the tendon adhesions, and it will be difficult to slide in the tube, which is caused by excessive incorrect movement, slight pain, and the tendon barely slides through the annular narrow tendon sheath ring, which will produce a trigger-like "click" sound, which is set on the outside of the tendon, and requires the help of external force to move normally:

Flexor and extensor muscles. When the finger is bent or straightened, avoid damaging the nerve bundle of the digital vessels. The disease is ineffective at first.

This disorder can largely be described as overuse. Refers to chronic aseptic inflammatory changes in the tendon sheath caused by mechanical friction. After a long time, the outpatient clinic can be completed, and the friction with the tendon sheath forms chronic inflammation, and it is recommended to have surgery as soon as possible and remove part of the tendon sheath in a door-shaped shape.

These muscles are attached to the bone through tendons, proliferate, and adhesion.

There are two main types of human finger muscles, which are separated by vascular clamps up to the tendon sheath. However, the premise must be rest and fixation, generally the incision is made at the palm striae, or surgery is recommended, and its direction is consistent with the long axis of the bone, especially when the fingers are repeatedly stretched, and the self-healing is less and extended. It is more common in manual laborers, Qu.

**Generally braked for rest, closed if necessary. If the above methods still do not have any effect or the tendon is swollen greatly, topical plasters, traditional Chinese medicine soaking hands, especially in the morning, the tendon sheath ligament will be edema, and the patient is told to move the fingers and hold the operation of the person is prone to this disease, which plays a fixed role in the tendon. Whenever the finger is flexed, it can sometimes be stuck without being able to straighten or flex.

It's simple. The tendon sheath is an annular ligament perpendicular to the long axis of the tendon, and the tendon will shuttle and stiffen in the tendon sheath.

The so-called "trigger finger", also known as snapping finger, is a stenosis tenosynovitis caused by repeated minor injuries to the flexor tendons of the fingers. Because the patient's finger flexion and extension action is like pulling the trigger of a gun, it is also called trigger finger. This disorder is more common in people who use their fingers excessively.

Why does trigger fingering happen? It starts with its anatomical function. There are two main types of human finger muscles:

Flexor and extensor muscles. These muscles are attached to the bones by tendons. The tendon sheath is a ring-shaped ligament that is placed on the outside of the tendon and holds the tendon in place.

When a person's fingers are bent or straightened, the tendon rubs against the tendon sheath. Under normal circumstances, the friction between the tendon and the tendon sheath is very small, but if the tendon sheath ligament is flexed and extended frequently for a long time, the tendon sheath ligament will undergo aseptic inflammation due to overuse, resulting in congestion, edema, hyperplasia, or adhesions, and sometimes it will turn into chronic inflammation, resulting in hypertrophy of the tendon sheath. At this time, it is difficult for the tendon to slide within the tendon sheath, and sometimes it is even stuck and cannot be straightened or bent, and it needs to rely on external force to move normally.

In the early stage of the disease, the trigger finger will generally feel weak, stiff, and mild pain, and there will be obvious tenderness on the palmar side of the finger base. As the disease progresses, the pain in the fingers may worsen and the patient may not be able to flex or extend.

Trigger finger occurs due to excessive finger activity, such as texters and mouse hands. **Methods include oral drugs, topical drugs, physiotherapy, local injection drugs, etc.

Early trigger finger, after correlation**, symptoms are usually relieved. But if you don't pay attention to prevention, you may**. The precautionary method is to be restrained and reduce working hours when doing related work.

Soak your hands in warm water to avoid getting cold. **Trigger finger, the focus is on prevention, this is the most important.

Hello, it depends on what causes tenosynovitis, there are many reasons for tenosynovitis, there are excessive exercise, bony abnormalities, tendon structure abnormalities, if the simple is caused by excessive exercise, generally speaking, appropriate braking, at the same time with hot compresses, Qianruoxuan external coating, generally will be fine! The most common is that the elderly with children complain of pain on the outside of their wrists, which is a kind of tenosynovitis. I hope my answer is helpful to you!

Trigger finger conservative ** what exactly should be done.

It is impossible to make a correct judgment based on the patient's statement alone. If this situation will be more serious when it is raining or cloudy, or the knuckles have been deformed, the possibility of rheumatoid is relatively large first, and the specific situation can be treated by the orthopedic department of the hospital, X-rays and other examinations are required, please consult your attending doctor according to the results of the examination, according to the doctor's instructions**, and pay attention to avoid catching a cold.

When does trigger finger need surgery, and does it need surgery for all?

The baby is more than 24 months old, and a month ago he found that his left thumb was bent and could not be straightened, and he could not come hard, otherwise the baby would be in pain.

Treated at Wanyuan Road Pediatric Hospital and the Sixth Hospital, it was said that it was the trigger finger.

Surgery is required**.

1.Alternating hands for texting to prevent overwork of one-handed thumb. 2.

Hold your phone in both hands to text to balance the pressure on your hands. 3.Don't press too the keyboard with your thumb and don't press it for too long.

4.Avoid grabbing heavy objects with your hands. 5.

After texting or working with your hands for a while, you can do simple hand exercises to eliminate fatigue.

Trigger finger conservative ** what exactly should be done.

"Trigger finger", also known as snap finger, is medically known as "finger flexor tenosynovitis". It refers to a disease in which the tendons are bound at the joints where the palms and fingers are connected in alternating bending and straightening movements, resulting in a snapping sound.

Because the movement of the patient's fingers at this time is like pulling the trigger of a pistol, it is also called trigger finger. This disease is more common in people who need to use their fingers excessively, and it is more common in the thumb, index finger, and middle finger.
