Trigger finger is a condition that causes stiff fingers in the same position. The disease mainly affects the tissue layer around the fingers called the tendon. Tendons are a thick fibre network that is related to skeletal muscle. Inflammation of the tendon causes the tendon to not move freely so that the fingers are locked in one place.
People of all ages may experience trigger fingers but usually this disease affects people over 45 years old and more women than men. This disease is said to be a professional risk of dentists, tailors, and leather craftsmen.
What are the signs and symptoms of trigger finger?
The fingers are often in a fixed position, trapped, or locked when folded or stretched. There must be someone who can straighten or change positions. Pain appears on the tendon and is often more painful when moving, and also swollen. Adults often feel pain in the middle finger while children are often in the thumbs up.
There may still be other symptoms not listed above. If you have certain concerns surrounding the symptoms of the disease, consult a doctor.
What is the cause of trigger finger?
Trigger finger occurs when the tendon layer of the fingers is irritated and inflamed. Tendons are fibre bands that connect muscles and bones. Each tendon is surrounded by a protective layer that affects the movement of the normal tendon. In addition, stimulating the layer will create scarring of the tendon and the layer will thicken, and cause fibrosis that makes the tendon movement more difficult.
What increases my risk for trigger finger?
There are many risk factors for trigger finger such as:
- same movement repeatedly. Jobs and hobbies that require the same hand movements and holding for long periods increase the risk
- certain diseases: diabetes, rheumatoid arthritis
- women are more susceptible Even if you do not have risk factors, it does not mean you can not experience this disease.
These symptoms are just as a reference. You need to consult a specialist for more details.
Trigger finger treatment
According to our trigger finger specialist, the best treatment for trigger finger aims to reduce inflammation and restore the movement of the tendon glide in the original tendon layer. In mild cases, symptoms may improve by avoiding the cause. Resting fingers with a special bush can help.
However, you may also injected steroids (cortisone) into the tendon through the palms (probably within the clinic). You may need injections more than once if the disease recurs. Injections will relieve symptoms in 65% of patients. Symptoms usually disappear within 3-5 days and the fingers may move again in 2-3 weeks.

Surgery treatment for trigger finger
At trigger finger specialist clinic, our doctor may recommend surgery should the conservative treatment fail. If the problem persists, our doctor may suggest surgery with anaesthesia. The procedure for trigger finger is release trigger finger. Then, the doctor will make a small incision wound on the surface of the palm and around the tendon tissue.
What are the usual tests for trigger finger?
At trigger finger specialist clinic, our doctors usually diagnose based on physical examination and symptoms, no need for tests. During the examination, the doctor will ask you to hold, open your hand, to check the hand area, as well as evidence of joint movement and stiffness. Your doctor may also touch your palm to see if there is a tumour. If the tumour is linked to the trigger finger, it will move along with the movement of the finger, as the tumour attaches to the tendon of the finger. The doctor sometimes uses blood and X-ray tests to rule out other possible causes of illness such as gout, diabetes, cracks, abnormalities thyroid, and carpal tunnel syndrome.
