C201601011 Tenosynovitis is also called snapping finger, trigger finger, and stenosing tenosynovitis. Tenosynovitis is an inflammation that forms at the junction of the tendon and tendon sheath lining and is a non-bacterial inflammation. When the hand is fixed in a certain position for repetitive and excessive activities, friction between the tendon and tendon sheath often occurs, resulting in edema and degeneration, causing narrowing of the tendon canal, resulting in pain and movement disorders, which is known as stenosing tenosynovitis.
This disease is common in middle-aged women and is characterized by localized pain, pressure, joint inflexibility, stiffness, and even a sudden jamming of the fingers, which can’t be moved and can only be released with the help of other fingers. It can affect activities such as pouring water, fastening buttons and typing. The joint stiffness is usually felt after waking up and is most obvious. It is common in some occupations that require long-term repetitive activities, resulting in tendon strain, as well as in tedious daily household activities, where the fingers and wrists have to work repeatedly, and in addition, people who cross-stitch and play mahjong for a long time are also prone to the disease.
Treatment to reduce local activities must be complied with, do not think that more activities get better faster. If there are recurrent episodes, patients with serious pressure need to undergo surgery, which is not very invasive, usually a small incision of 2 cm to open the narrow part of the tendon sheath, and partial excision and release can be cured. The postoperative results are often closely related to individual differences, postoperative rehabilitation, and compliance with medical advice.
