Trigger finger, also known as Tenosynovitis Stenosing, is a type of disease that is responsible for snagging and sudden locking in the fingers. In this disease, the fingers that contract involuntarily and for a certain period of time also cause severe pain. In the treatment of this disease, which makes daily life and especially handicrafts very difficult, some muscle relaxants and different drug treatments can be tried first. However, if these methods do not work, the disease should be treated by performing surgical operations with microsurgery techniques.
