What is tenosynovitis?

Any disease is seriously harmful to human health. Therefore, when treating the disease, we must choose the correct treatment method, which will be of great help in improving the disease problem and prevent the disease from continuing to develop. So what is tenosynovitis? Many people are not very clear about this issue.

Many people do not know much about what tenosynovitis is, and when this happens, they do not know how to solve the problem. When this happens, go to the hospital for examination first so that you can know the specific situation, which will be beneficial for disease treatment.

What is tenosynovitis?

1. Radial styloid stenosing tenosynovitis

Two tendons pass through the first fibrous bone sheath on the dorsal side of the wrist, namely the tendons of the abductor pollicis longus and the extensor pollicis brevis. After passing through the narrow sheath, the two tendons form a certain angle with the sheath and end at the base of the first metacarpal bone and the base of the proximal phalanx of the thumb, respectively. When the wrist and thumb have a wide range of motion, the angle of the tendon increases. Over time, the local synovium becomes inflamed and thickened, the tendon becomes thicker, the fibrous sheath wall also thickens, and subcutaneous nodules appear at the radial styloid process, making it difficult for the tendon to slide in the sheath, causing symptoms such as pain.

Due to endocrine changes in lactating and menopausal women, the synovium is easily affected and this is the main reason why the disease is more common in women. In addition to the above reasons, according to our surgical observations and foreign literature reports, there are many anatomical variations that can easily cause the occurrence of this disease. For example, if the belly of the palmaris pollicis longus or the extensor pollicis brevis is too low, part of the belly may enter the sheath; because there are more vagal tendons in the sheath, the number of tendons increases significantly, with some having more than ten tendons; there are also hard, thick and tough fibrous septa in the first dorsal wrist sheath, which makes the originally narrow sheath even narrower and the tendons are easily incarcerated. These anatomical variations cause the disease to occur at a younger age and make conservative treatment difficult to be effective.

2. Myosinitis

The radial extensor carpi longus and brevis muscles are located on the deep side of the proximal end of the dorsal carpal ligament, and the extensor pollicis brevis and abductor pollicis longus muscles pass through the superficial side at a certain angle. When muscles are overactive, the muscles, tendons, and the surrounding fascia and peritendinous tissues become congested and edematous. The synovial fibrinous exudate increases, and symptoms such as local redness, swelling, and pain appear.

Through the above introduction, we have a good understanding of what tenosynovitis is. When treating such a disease, the diet should be arranged reasonably, and more fruits should be eaten, and the choice of seafood should be reduced. This will be of great help to all aspects of the body and improve physical diseases.
