What is meant by key sheath inflammation

Tendon sheath is a double-layered casing-like closed synovial tube that covers the outside of the tendon and is a synovial sheath that protects the tendon. It is divided into two layers encircling the tendon, a cavity between the two layers that is the synovial cavity, within the tendon sheath synovial fluid. The inner layer and tendon close together, the outer layer lined with tendon fiber sheath inside, *** with the combination of bone surface, with fixed, protective and lubrication of the tendon, so that it is free from friction or compression role.

Tendon sheaths have the function of maintaining the normal flexion and extension of the fingers and the sliding of the tendons. When the hand is fixed in a certain position for repetitive, excessive activities, so that the tendon and the tendon sheath often friction between the tendon, resulting in edema, fibrous degeneration, caused by the narrowing of the internal cavity. Due to the tendon in the tendon sheath activities, through the narrowing of the pathway, resulting in pain and movement disorders, this is tendovaginitis, also known as stenosing tendovaginitis.

Second, tenosynovitis classification

(1) radial tuberosity stenosis tenosynovitis tenosynovitis slow onset, gradual aggravation, the wrist side of the thumb (radial tuberosity) and around the thumb pain, thumb activity is impeded in the radial tuberosity pressure and friction sensation, and sometimes in the radial tuberosity there is a slight elevation of pea-sized nodules. If the thumb is held tightly within the other four fingers and flexed to the medial (ulnar) side of the wrist, severe pain occurs at the radial tuberosity. In the acute phase, localized swelling may be present. When the enlarged tendon passes through the narrow tendon sheath this "tunnel", the thumb in the flexion of the thumb, there will be a sound, which is also known as "playing ringing finger".

(2) Flexor tendon tenosynovitis occurs mostly in the thumb and middle finger. Flexion and extension dysfunction of the affected finger is particularly obvious when waking up in the morning, and can be alleviated or disappeared after activities. The pain sometimes radiates to the wrist. Flexion of the metacarpophalangeal joint may cause tenderness, and sometimes thickened tendon sheaths and pea-sized nodules can be detected. When bending the affected finger, it suddenly stays in the semi-bent position, and the finger can neither be straightened nor flexed, as if it is suddenly "stuck", with unbearable pain and soreness, and after triggering it with the assistance of the other hand, the finger is able to move again, generating trigger-like movements and popping, so it is also known as "trigger finger". "The first time I saw it, it was a very painful and painful experience, and I was able to move it with my other hand.

Three, the treatment of tenosynovitis

Tenosynovitis treatment: the affected area can be used for heat therapy, massage and adequate rest for about 3 weeks, especially to reduce the disease caused by manual labor. Local closed treatment, can make the early tendonitis relief, closed once a week. If the above treatment is ineffective or recurrent, tenosynovectomy should be performed, and after the operation, early finger flexion and extension activities should be done to prevent tendon adhesion. After surgery 1 month free from manual labor.

Four, tenosynovitis daily care and exercise methods

1, wash your hands with warm water

Recreate the habit of washing your hands with warm water after work, should not use cold water, and move your hands at the right time, and massage yourself. This is the first time I've ever seen a person with this disease, and I'm not sure if I've ever seen a person with this disease before.

2, rotate the wrist

When the tingling begins, you can do some gentle hand movement to relieve the pain. Rotating your wrist is one of the simple exercises. Rotate your wrist for about 2 minutes. It can exercise all the wrist muscles, restore blood circulation, and eliminate the bent wrist position, a bent hand position that often causes wrist pain and other symptoms.

3. Lift your arms

Lift your hands above your head and rotate your arms while rotating your wrists. This helps your shoulders, neck, and upper back adjust to their position and relieves pressure and tension.

4, rotate the head

Take a break from work, put your hands on the table and rotate your head for 2 minutes. Bend your neck forward and backward, point your head at both shoulders, twist your neck, look at your left shoulder, look at your right shoulder.

5, regular exercise

Daily exercise and relaxation of all sore muscles is very important, even if you do not feel pain. The localized exercises described earlier should be practiced at least four times a day.

6. Elevate your hands

When you're resting, avoid keeping your hands below your shoulders. Support your elbows with a tabletop or lean them against the chair handle. Keep your hands facing up. This is beneficial resting posture.

7, clenched fist exercise

Gently make a fist, then open it and straighten your fingers. Repeating this exercise helps to relieve tingling.

8. Avoid drooping arms

When you sleep, keep your arms close to your body and your wrists unbent. If you let your arms hang over the side of the bed, it will increase the pressure on your hands.

9. Be careful with tools

When using tools, don't concentrate pressure at the base of the wrist. Try to use your elbows and shoulders.
