Stenosing Tenosynovitis, commonly called ‘Trigger finger’ is the painful condition in which one of your fingers gets stuck in a bent position. Your finger may straighten with a snap sound, like a trigger being pulled and released. It occurs when there is an inflammation in the tendons of the affected finger. Tendons are tough bands of tissue that connect the muscles and the bones. Tendons and muscles function together, for the fingers to bend or straighten. The inflammation narrows down the space within the sheath of the tendons. Therefore, the motion of the tendons gets restricted and creates a pop sound during movement. Trigger finger is commonly observed in people with occupations involving repetitive gripping action in the fingers. Also, the disorder is mostly observed in women and those with diabetes.
