Trigger finger

Trigger finger is a condition when the finger gets stuck after flexion, and can be extended only with an effort or with help of the other hand, and there is always a „clicking“ sound associated with that maneuvre.

How does it develop?

The reason for developing is unknown, but it is presumed that it derives from an inflamed extensor muscle tendon. As a consequence of this inflammation, there is a problem with extending the finger.

Symptoms and signs

The basic symptom is „stuckage“ of the finger after palmar flexion and the inability to extend it without the help of the other hand.

This symptom is usually accompanied by clicking and pain when forcefully extending the finger, as well as pain in the palm and the whole hand.

How is it diagnosed?

Diagnosis is set by a clinical examination with some functional and finger mobility tests. It’s also necessary to feel (palpate) the tendons and the canals through which they pass.

How is it treated?

The treatment can be surgical and non-surgical.
