What is a trigger finger?
In trigger finger, the flexor tendon of the finger becomes irritated and may develop a thickening. As a result, the tendon does not glide smoothly through the tendon sheath, causing the finger to catch during movement. Sometimes the finger suddenly releases with a clicking sensation, which can be painful. The condition most commonly affects the ring finger, middle finger, or thumb (trigger thumb) and may occur in one or multiple fingers.
Causes of trigger finger
Trigger finger often develops due to overuse or repetitive gripping, for example during work or hobbies that involve frequent pinching or repeated hand movements. It also occurs more often in people with conditions such as diabetes or rheumatoid arthritis. In some cases, there is no clear cause and the condition develops gradually.
Symptoms of trigger finger
- Pain or tenderness at the base of the finger or thumb (palm side)
- Stiffness, especially in the morning
- A clicking or snapping sensation when bending or straightening
- The finger catches or suddenly releases
- In severe cases: the finger temporarily locks in a bent position
- Sometimes a palpable lump in the palm near the affected finger
Diagnosis of trigger finger
The diagnosis is usually made based on your symptoms and a physical examination. The doctor assesses the catching or clicking of the finger and may feel a thickening near the tendon. Imaging tests are usually not necessary.
Treatment and recovery
Treatment often starts with reducing strain and temporarily avoiding painful gripping activities. A finger brace or splint can help by giving the finger rest and reducing catching, especially at night or during activities. In addition, exercises, physiotherapy, or an anti-inflammatory injection may be used; in persistent cases, a minor surgical procedure may be required. Recovery can take several weeks to months, depending on severity and treatment.
Supportive finger brace for trigger finger
A finger brace (or splint) can be very helpful for trigger finger because it keeps the finger in a neutral, resting position and limits movements that provoke catching or “snapping.” This gives the irritated tendon and tendon sheath more rest, which can reduce pain and stiffness and often decreases triggering. This is especially useful at night, as many people unconsciously sleep with their fingers bent, putting extra strain on the tendon. By supporting the finger at night (and, if needed, during demanding activities during the day), repeated irritation can be prevented and recovery can progress more effectively. A brace does not guarantee that the condition will completely resolve, but it is a practical way to offload the finger and reduce symptoms in daily life.
Which braces are suitable for trigger finger?
For trigger finger, braces are suitable that provide targeted support to the affected finger without unnecessarily restricting the rest of the hand. This is often a splint that holds the finger (or the involved joint) in a more extended position, so the tendon is less likely to become “caught” during bending and straightening. A good brace should fit securely without being too tight and should not cause pressure points, especially when worn for long periods at night. A practical brace is lightweight and comfortable, easy to put on and take off, and stays in place well during sleep or daily activities. Because the affected finger (for example, ring finger, middle finger, or thumb) and the exact location of the catching differ from person to person, advice from a ProBrace specialist is recommended to ensure the correct fit and optimal wearing schedule.
Benefits of a finger brace for trigger finger
- Provides rest to the tendon and reduces irritation
- Helps reduce catching, clicking, and “snapping”
- Relieves pain and stiffness, especially in the morning
- Prevents overuse by limiting movements that trigger symptoms
- Supports finger alignment at night and provides more control during the day
