Trigger Finger (Stenosing Tenosynovitis)

Trigger finger (trigger thumb), also known as stenosing tenosynovitis in medical language, is a disorder of the tendons that allow the fingers to bend in the hand and the bridges (pulleys) that they pass under at certain points.

Tendons are in the form of a long rope starting from the forearm muscles and continuing to the fingers. Pulleys are the structures that the tendons pass under at certain points and provide the movement of the tendon. These pulleys bring the tendon closer to the bone. It is a thin structure that allows the tendons to slide comfortably in the tunnels around them (tenosynovium). The thickening of the scale at the base of the finger, sometimes due to swelling of the tendon sheath, and sometimes due to swelling of the tendon sheath, causing snapping and pain during the movements of the finger is called trigger finger. It is more common in systemic diseases such as rheumatoid arthritis, gout and diabetes. Trigger finger starts with a feeling of discomfort at the attachment point of the fingers to the palm of the hand. There is tenderness with pressure on this area. Sometimes nodules (hard swellings) can be felt in this area. In advanced periods, the finger starts to get stuck and locked. Consult your physiotherapist for correct diagnosis and treatment.
