Trigger Finger

Trigger finger, or trigger thumb, occurs when the pulley at the base of the finger becomes too thick and constricting around the tendon, making it hard for the tendon to move freely through the pulley. Some symptoms of trigger finger/thumb include tenderness felt at base of finger or thumb, and painful popping, catching or even locking of the finger/thumb when flexed or extended. Treatment options include wearing a splint or taking an oral anti-inflammatory medication. Symptoms can often be relieved by a steroid injection into the area around the tendon and pulley.

If symptoms persist or are severe, surgery may be recommended. The goal of surgery is to open the pulley at the base of the finger so that the tendon can glide more freely. After surgery, some patients may feel tenderness, discomfort, and swelling in the area of surgery; however, for the most part, normal use of the hand can be resumed once comfort permits. Hand therapy is sometimes required to regain better use.
