- Trigger Finger is experienced as a pain in the palm just below the finger. The finger gets stiff and may snap or even lock. Often, the symptoms are experienced in the morning.
- It is caused by swelling around the flexor tendons which bend the finger. They get stuck the tunnel of fibrous and connective tissue which holds them snug against the bones. The swollen tendon sheath “bunches up” in the palm at the entry of the tunnel. As resistance is overcome, the “knot” of swollen tendon sheath “snaps” in or out of the tunnel causing a sudden jumpy movement which may be painful. Eventually, the snapping stops and the finger is just stuck.
- Nonoperative treatment for trigger finger has a high rate of success. Often a cortisone shot and/ or activity modification is all that is needed to correct the problem. A single injection can cure up to 80% of cases. A second one can raise that rate to 90%. In some cases, nonoperative treatment fails and surgical release of the first “pulley” in the tunnel will be needed. This is a minor outpatient procedure which can be performed under local or general anesthesia.

Hi, as a young orthopedic surgeon I am going to specialize on hand surgery. My passion are climbing injuries. Beside Pulley ruptures (mainly A2 and A4) there is a common overuse syndrome: An isolated pulley inflammation. After Ultrasound diagnostic I usually inject some corticoid. It has a very good outcome.
Like you I start my social media experience (in german). I would like to ask for permission to use your picture of the injection. Thank you very much. Johannes
I agree. Sometimes pain along the sheath without frank triggering responds well to injection. Feel free to use pic.
