Trigger finger happens when a tendon in the finger gets stuck within its pulleys, small bands of connective tissue that keep the tendon in place. The tendon cannot move smoothly, causing the finger to lock or catch. It may bend and then suddenly pop straight, like pulling and releasing a trigger.
Trigger Finger
Repetitive motions and injury to the fingers can cause the finger pulleys to become inflamed, which can restrict the ability of the finger tendon to move smoothly. Pain, clicking, and limited movement of the finger often result from trigger finger.
Treatment for trigger finger will depend on the severity of the condition. If detected early, splinting, physical therapy, and injections may help. In more advanced cases, surgery may be needed to help the tendon move more freely.
